Dealextreme review: Produino Digital Mobilize/Cycle Time Delay Relay Module

[@blueckaym]

18 seconds in the video I found what I was looking for! Thanks man!!! I've seen many of those relays srd-05vdc-sl-c that operate on 5V (commonly used with RaspberryPi & Arduino), but I needed one with control-coil operating on inbetween 20~30V, and the SRD-24VDC-SL-C model would be almost perfect for my purpose (a custom build DC-only UPS). To be 100% perfect it should be Double-Pole-Double-Throw Solid State Relay, but I guess I can use two of these SPDT SRD-24VDC-SL-C relays sharing their control-coils, and their Common-poles, with the addition of a good Capacitor (in order to sustain the Voltage & Current output during the relay bouncing). But if someone can point me to a SSD DPDT relay that operates on around 24V I'll greatly appreciate it! And if there's one with AVR that can be set to output stable 19V it would be 200% perfect! :)

[@csongorvarga]

I did a quick search, I could not find a DPDT solid state relay either. But there are three phase solid state relays available. That would be a better choice than using two modules.

[@blueckaym]

Most 3Phase SSR I've seen are for much much higher loads - like ones measured in kW - and are very heavy. I wanted to make a portable power-bank in between 1.5~2kg tops. Actually the batteries alone are between 800~1100gr (depending on my choice between 3 or 4 parallel cell-pack /in 6 series/). EM Relays like the one in your video are about 30gr each I think, so I guess I should keep educating myself and make my own switching and charging-discharging-protection circuits in order to keep it light. And it seems a good capacitor (and a diode) should help with the EM relay bouncing. Thanks for the suggestion non-the-less - I'm still gathering info so any advice or opinion is very helpful!

[@martyjackson4806]

Thanks for making this video. Yours is the only one that I'v e found that says that if you set it and power it off and on it will run the selected program. Good to know!

[@kenwasnorowicz2905]

Great stuff , jus ordered one , needed this video

[@omardude39]

I'm going to use this board for a "delayed entry door" build. Haven't quite worked out which mode is the right one yet, but I'm certain that one of them is correct! In my project, a door will be secured closed by a magnetic lock. When somebody wants to go through the door, they push a button (the trigger input), wait for 10 seconds, and then the magnetic lock will turn off so the door opens. After three seconds, the lock will turn back on.

[@csongorvarga]

This is a good idea. I think you can use mode 13, with t1=10 sec and t2=3 sec. But when you wire the lock to the relay connect it to COM and NC. So when the relay turns on, it actually disconnects the power to the lock.

[@omardude39]

Thanks for the reply - I agree. Out of interest, once the relay reverts to the 'lo' state, if the trigger input is used again, will it re-run the sequence of T1 and T2, or must the board be reset before it will run again?

[@csongorvarga]

+Omar Smith yes, it will re-run the sequence.

[@junglerumble9703]

youre awesome ive been looking everywhere for one of these thanks!

[@tt986903]

When purchasing this (waiting for it to arrive) I noticed that there are a couple of things that aren't in the item description and maybe you can answer. There are jumper settings toward the top of the board, what us this for? Also seems as though as there are a couple different empty spots on the board such as sensor and what looks like TR, have you any idea on what there could be used for? Thanks for the great video. We appreciate it

[@csongorvarga]

+Paul Palumbo The jumper on the top is to set if the trigger is a high or a low trigger. I have to admit I don't know how the low trigger works. I tried in high mode and it was working fine. Again I have no information of the trigger is TTL level only, or can be same voltage as the supply voltage. I tried with 5V. I have no information about the unpopulated parts. But there is nothing in settings that would suggest that additional sensors data can be taken into account.

[@tt986903]

Thanks, I appreciate the quick reply! Cheers

[@omardude39]

Unless you're willing to experiment (and possibly sacrifice) a module, you should probably presume that the markings with no components are redundant on the board you have bought. They will either be non-functional (most likely), or could permanently destroy the microchip. Chinese manufacturers often use the same board design for different variations of a product because they might as well. It is likely that the unconnected parts will either do nothing, or cause the chip to crash because it isn't programmed to handle the input.

[@tt986903]

i appreciate the info, make sense! Cheers

[@Amerocob]

I'm using mode 11 as a sleep timer for a heater coil. Being able to reset with the countdown visible is nice.

[@joshjcochran]

This was a HUGE help! Thanks!

[@adolfomolinam]

I need one shot / single shot. when power on, or with trigger, to close the relay for few seconds and then open the relay indefinitely even dough is receiving power. Can this piece do this?

[@aladino10100]

Thanks for the video, crystal clear (except a typo in the legend Model 10). As I'm going to make a solar powered application, is there any way to cut consumption? (40-120 mA I heard). A couple of ideas: cut off display once the set is given? Install a latched relay? Anyway, compliments and thx. Manlio

[@csongorvarga]

Thanks for your comments. I am not sure you can reduce the consumption other than disconnecting the display. Or maybe an solid state relay? I never used those, I am not sure if it is lower in consumption or not.

[@charlescho]

What are some uses for this thing?

[@914peru]

i have a pellet stove an the potentometer that controls the auger is broken probably a could use it?

[@csongorvarga]

+German Almonacid Yes, probably you can use it to periodically turn the auger on and off.

[@Back_to_the_Future_3]

I am looking to use this in the car. It will be used for cameras which are already controlled by the ignition switch. On when running or accessory position. What I would like is to have this keep the power on after the car is completely off for a couple hours at least. However I don't want the timer to control the cameras while the car ignition switch is on/acc (No timed turn off). Any ideas?

[@csongorvarga]

+1971elco I am sorry, but I don't think you will be able to use this for that.

[@wisdom_wellness365]

Awesome! Thank you so much!

[@ABIZAR_PRISTEL]

if i want to instal in inqubator egg timer,how its wiring

[@TheHellis]

Hello! Thanks for the video, very good information. I'm thinking of building a phonecharger in my car that will charge the phone while the car is on and for one hour after I shut of the power. Would that work with mode 11? What I'm thinking is add a new cigarette lighter socket that will have to positiv cables, one from ignition and one from the circuit. The trigger will be connected to the ignition but with the pin low. Does that sound correct? Possibly a diod between ignition and circuit and between ignition and cigarette lighter socket to make sure it does not keep the car "on".

[@csongorvarga]

+TheHellis I did exactly the same application. I built a charging station for my cordless drill and electric hedge trimmer. I am using mode 1 which is a off delay. The positive lead first goes to the relay and from the NO terminal goes to the power input of the relay. So even when the power is applied the timer does not start. I have a small push button which will apply power directly to the circuit. It starts the ON cycle, turns the relay on, which gives power to the circuit. So I only need to hold the button for about 1 sec after that the cycle starts. After the ON delay the circuit turns the relay off, which also cuts the power to itself. I did the build already, created videos as well but did not have the time to compile the video and upload to youtube.

[@uldragos]

I'm not sure it's a good question: after power off, does it remember the last settings ?

[@csongorvarga]

Yes, all the settings are retained after power off: mode and time settings.

[@Duckyistrippin]

Is there a timer like this, but allows for finer adjustment for periods of less than a second? like a 0-9.99 second timer?

[@csongorvarga]

+Duckyistrippin I have not seen any sub-second timers yet.

[@nathand795]

Aim is to power a oil scavenge pump for 60 seconds when car is switched off it will keep power then turn off. Mode 11 can i use this to hold a trigger (12v+) signal and as soon as singal power is stopped (the trigger) then the timer is triggered to hold T (programmed time) before going low / off again. is it fine to handle leaving a pro longed trigger in place (engine on for hour/s) before its trigged... Thank you.

[@csongorvarga]

I was about to suggest Mode 11 as well. But I don't know if the trigger is on level, raising edge or falling edge. I would need to test this to make sure. But if the +12V trigger does not work, I would change the jumper so the trigger is a low trigger which will trigger when the +12V goes away.

[@cvanhoose2000]

Can you send a link where you purchased these?

[@csongorvarga]

It is all there in the video description.

[@Deqster]

Does this provide a single cycle option? Also what's the resolution and minimum delay value? I'm trying to build a circuit that will have a single cycle on for a range of about 0 to 100 milliseconds.

[@csongorvarga]

It does single cycle, but the smallest resolution is 1 second.

[@Deqster]

+Csongor Varga Ok thanks, I won't waste $12 or whatever on it then. Thanks for the video!

[@youtubo9833]

Hi. I have a question. If you put any of the programs and change the values, when you disconnect, at restart the cycle it save what has already been programmed?

[@csongorvarga]

Yes it does. All settings are stored and retained.

[@youtubo9833]

Great Thank you

[@gtag174]

great video mate. Would the module be capable to set time below 1 second like 0.1 or 0.5 ?

[@csongorvarga]

No, 1 second is the shortest increment.

[@gtag174]

+Csongor Varga the description says a lot about 0.1 seconds mentioned here www.ebay.com/itm/271958222133 that was kind of confusing. So thought since you already have it you could check it out. Would you be knowing a module that could be set delay the relay for less than a second.

[@csongorvarga]

+George Thomas the product on the ebay link is a different model. That might do 0.1 seconds. There are loads on these online.

[@gtag174]

+Csongor Varga thanks a lot mate. Hard to understand from the description alone. Will try that and see if it can help me with my project.

[@csongorvarga]

+George Thomas I had a second look again, but I think it will work for you. As you said the description is hard to understand and almost impossible to be certain what they mean. What you need is a very simple off delay which is a pretty basic function, therefore it must do that. Just make sure the relay can handle the current.

[@tasteofkozhikode9393]

i have one motor and timer switch(frm01) with me I want to know if it will work as automatic or periodic timer switch to initiate the motor every hour turning it one (one full rotation) .. How can i connect motor and relay borad(frm01)

[@csongorvarga]

I don't think this can be used. This board has a on/off cycle timer which is what you want, but the timer value can either be seconds or minute. If you choose second, the timer values can only go up to 999 seconds which is less than 1 hour you need. If you use minutes, I assume it will be too long for a full rotation.

[@junglerumble9703]

Hey i was hoping you could answer my simple question. I am trying to run a dc motor on 5. this is my second modulator that ive bought and i can not seem to get any output out of it. I must be wiring it incorrectly. How to you wire it? I do not need a switch. Thank you very much.

[@csongorvarga]

I am assuming the board is connected OK and running. The blue relay is like a switch. You run one wire from your power supply or mains directly to your motor and the other wire goes to the centre terminal of the relay and from the lower terminal to the motor.

[@junglerumble9703]

thanks for your help, i just figured it out an hour ago ha.

[@plavaolovka]

Do I have to set program each time when I power it on? Or will it remember last program...

[@csongorvarga]

Yes, it remembers the mode and all other settings.

[@AdamiXko]

On mode 11, does it start to count after touching the trigger with positive lead, or after release of the trigger from the positive lead? Thanks

[@csongorvarga]

Hi. It triggers on raising edge (when touching the positive lead).

[@AdamiXko]

Csongor Varga so when i will hold the trigger on positive lead for example 5 seconds, it will start to count with this 5 second or after i disconnect the trigger? I am searching for something which start to count after disconnecting the trigger

[@csongorvarga]

AdamiXko No, as soon as you touch the positive lead it will start counting, but... there is a jumper to set if the trigger is on positive (raising edge), or negative (falling edge). So it might be possible for what you need, but I have not tested that.

[@elementdude195]

I'm not too familiar with electronics, but I think this will meet the application need. I did come across 3 questions if someone can answer them before I buy. I'm trying to use this for a specific model train situation. It's using AC power, but I got bridge rectifiers to convert it to DC. 1. If I power up the board with around 10-13v DC to the 12v board will that break it? 2. If I power up the board with around 13v DC or higher but not 24v DC to the 24v board instead will that allow it to power on safely? 3. I want to use mode 10. After I set the mode if I have the trigger port directly wired to the DC + port of the board consistently so when the board turns on it will be low already and instantly start to count down than switch to high after that and my other relay will shut off the board power and repeat without issues. Will that work? Insight to this will be appreciated Thanks!

[@csongorvarga]

+elementdude195 These are valid questions, but I don't think I would be able to answer. I can just assume that the chip running the logic has a voltage regulator which would probably accept higher than the rated voltage. The relay on the board is usually rated to the input voltage so a 24V relay may not work with 13V supply. I suggest to get a 12V version. For your third question I only used a 5V board with 5V as the trigger voltage. I don't know if there is any input protection single it is not specified. But if you want to start the cycle when the board is turned on, you can use mode 2 for on delay as well. I suggest you get one and try it out before placing an order for an entire batch.

[@manojkailas90]

thank you for this video i use this relay for one of my project your video help me a loat

[@saqibmian2010]

i have a question i need this to run a small motor.. with a foot pedal.. basically the motor pumps oil and i want to fill a bottle with it.. but i want it to turn off as soon as i fill the bottle.. and when i hit the foot pedal turns on again.. i have a motor/foot pedal/ (12v) and im about to order this.. (also have a adjustable voltage regulator) but i'd like to put this in line so as soon as i hit the foot pedal the tube fills the bottle with oil( i can see how long it takes to manually do it and set a time exp 6 seconds 10 seconds.. but i'd like to know if this can be programmed) to turn on with flipping the foot pedal and turn the power off on its own.. and i'd put a new bottle and start the cycle over again.

[@csongorvarga]

+Muhammad Mian Yes, and I used mine for exactly the same purpose. I set mine up as a charging station and turns of when I push a button and after 6 hours it turns off. Btw, there is also a 12V version of this, so get that and you don't need a voltage regulator. In my application the push button applies voltage to the board, and it starts mode 1. In mode one the relay comes on for a predefined time. I also connected the power to the relay, and in the "on" state, the power is fed back to the boards. So you can release the push button after 1 second and the board powers itself. Once the delay is over relay turns off which also cuts the power to the board. And of course the cycle starts again when I push the button next time.

[@saqibmian2010]

+Csongor Varga perfect thats exactly what i wanted to know. the reason i got an adjustable voltage regulator is because its a 20gpm pump and im filling 1 oz bottles with oil.. and it would be too much pressure.. i did not want to put a valve in the hose because i would end up over loading the pump.. so i have the variable voltage regulator. ok so mode 1 is where i need to be and then set the timer to the desired "on" time (for me that would be seconds)

[@csongorvarga]

+Muhammad Mian Yes. You may be able to find different models with only 2 digits specifically designed for on delay mode only. In case you can to save a few bucks. I got this because I needed 6 hour delay which only works if the board supports minutes and 3 digits.

[@terencebarry1804]

I have a 12V timer. Can I trigger using 12V, or does the trigger voltage have to be 5 V?

[@csongorvarga]

+Terence Barry I don't know. There is nothing in the "documentation" to state that. I assume it is 12V but you need to give it a try. There is a jumper to set if the trigger is high or low. Maybe set it to low and try with a ground trigger.

[@terencebarry1804]

+Csongor Varga Thanks for getting back to me. It works with 12V! The pin was in the high position.

[@terencebarry1804]

+Terence Barry By the way, GREAT video. Very helpful.

[@upekshachathurani4939]

hii, i need to know about the triggering,does one pulse sufficient for one cycle (on-delay then off). how you supply trigger here? thank you.

[@csongorvarga]

I am not sure what your question is. One pulse was enough to trigger the module, but I did not test how long that pulse needs to be.

[@upekshachathurani4939]

Csongor Varga it means when we supply one pulse it operates continuously, ? Sir, I need to make a circuit ON for 2seconds and Off for 28seconds and this should be done for 4000 times. Can i use this module? Can I use PIC 16f877a to provide a pulse, because I am using it for programming.

[@csongorvarga]

It cannot exactly do that. The trigger mode only does one cycle. But there is a mode where it does the on-off cycle 4000 times after it is powered on. So I would suggest that PIC turns on the power for this unit instead of sending a trigger. And the PIC keeps this output high for 120,000 seconds and turns it off. And turns on again when the cycle needs to start again.

[@upekshachathurani4939]

Csongor Varga okay, thank you very much. great. (y)

[@carlosaristy6809]

Hello I would like the video to have subtitles, I do not know English I am Spanish

[@gtag174]

Wanted something like this for a diy spot welder. One second is way too much to spot weld with.

[@technicalrk9546]

Sir help me .I want buy,which model timer it is

[@csongorvarga]

As I said, the link is in the video description.

[@technicalrk9546]

Csongor Varga thank you

[@karloschweiger5256]

Hi, Can you tell me this before i buy it. I need use it like this: if ti get a contact from trigger relay works for 5 sec than it goes off, but if it get a contact and it starts to work BUT after 2 second it lost contact from the trigger it must stop working, it must work for 5 sec only if trigger on. Which mode is that? Thank you

[@csongorvarga]

For this module the trigger only starts the cycle, but it has no influence on it after. So the answer is no.

[@karloschweiger5256]

But if turn it off and turn it on it will automatically count seconds to off?

[@csongorvarga]

Yes, it always counts the seconds before going off, but the it will always go off after 5 seconds no matter what.

[@karloschweiger5256]

it wont if i turn off vcc or gnd from it

[@csongorvarga]

Of course, if you cut the power the relay will go off.

[@seanosomething]

Can i switch between modes automatically? I want an "on off" cycle for daytime and a different "on off" cycle for night time Is this possible??

[@csongorvarga]

+seanosomething No, you would not be able to do that.

[@seanosomething]

is there a way i could switch between two separate regimens? Maybe add another unit?

[@csongorvarga]

+seanosomething maybe you can use two units but I can't tell for sure.

[@seanosomething]

Csongor Varga Thank you.. great video too... good to see someone finally decipher the ridiculous instructions! Nice one..

[@nsmcastillo326]

Can it handle 110 Volts?

[@csongorvarga]

Yes, the relay can handle 110V.

[@samaragiri]

I want some thing turn on something every one hour and off' one second. can do it.. thank you.

[@csongorvarga]

Not this one. This can do on-off cycles, but either 0-999 seconds or minutes. So either both the on and off cycle is minutes or seconds. You can have 16 minutes off and 1 second on, or 1 hour on and 1 minute on.

[@samaragiri]

thank you

[@raygraham8972]

The FRM01 has a 0-9999 sec. range that may work for you.

[@MGrahamMakes]

For those interested I've created a set of instructions and a free 3D printable case file for this timer device here: www.thingiverse.com/thing:1517170

[@csongorvarga]

+EngineerDog Thanks for this, the case looks great. But mind that your board is slightly different. It does not have the trigger input and the components are laid a bit different.

[@Moontanthefirst]

Thanks for this info. May I say that if you spoke slowly and arranged the microphone better, it would be even more useful. I can just about glean what I need from the video.

[@thesupplement]

I have seen a lot of these types of videos, but they all fail at one thing (for the benefit of the ignorant or beginner), they do not explain what the power source is or how they start the relay (switch type, etc.). Could you show or explain the aforementioned particulars?

[@csongorvarga]

I am not sure what you mean. I (believe) said that this is version runs on 5V, but there are similar models for 12V and 24V supply voltage. Not sure what else you need to know about.

[@isademir4887]

Böyle bi rolem var ayarlayamıyorum bana yardımcı olacak kimse yokmu

[@menzoberranzam]

This is almost exactly what I need, except i need one to stay 15 seconds on, and 7200 seconds off...

[@izabellavargazsok]

+Hugo Barros de Souza I think you will be lucky if you can find something like that off the self.

[@siku5it]

Thank you. This is what I have been looking for for some time. - As I needed something to work in delays of about 23 hours.. this specific one wasn't the right one. So I purchased this one that promises to have 9999 minutes / or seconds. www.ebay.com/itm/221587706208 - It seems to have a similar working pattern. - What I need to do is to turn on an RPI - It will boot and perform certain operations.. in all it should last for 5 minutes.. then the RPI will shutdown (go in a halt mode), then the timer will remove the power. This should create a machine that should use very little power over time. I am planning to use a LiIon battery to power both the timer and the RPI. - Considering the majority of the time the relay will be in the disconnect state it will use very little power to wait for next triggering time... Thank You !!

[@csongorvarga]

Evo Archer Thanks for the link, that looks like a good alternative product. Actually I purchased mine for the same purpose. I wanted a timer which turns the power off from the charger for my hand drill which I only use weekly or monthly and usually I forget to go back to my workshop to unplug it.

[@hernes0071]

Well to me 1 sec is way too long.

[@petergilliard1981]

well done my friend. You should quit your day job and go in to full time Utube production

[@csongorvarga]

Hopefully, I will get there at some point, but I am not there yet. Also it is very difficult to guess what people are interested in. But this review is (one of) my most popular.
