Programmable triggered timing board 35238 MP

[@Rick-bx1fb]

After searching for 1.) How to wire a little relay like this. 2.) How to program one. I have to say this is the best video out there! A lot of them go on and on with various circuit board/technical terms. But this tutorial shows how mpjaonline had it wired up, (thats the main thing that helped me past my hurdle!). This video saved my Halloween Prop! Much thanks!

Bought two on sale , no instructions in the box. After attempting to decipher the vendor`s online nstructions for 5 minutes , not well translated from whatever language they were orginally written I might add.I searched for a video hoping to find one coherent and intelligible, I found this video ... I wish I had found the MPJA webstite from the start ..it will be my go to from now on . THANK YOU FOR MAKING THIS TUTORIAL VIDEO , CONCISE EASY TO FOLLOW AND UNDERSTAND , superb job .

[@beknowwhy]

Thank you for making this tutorial so simple and understandable.

[@smknewman]

There is one more function: Hold down up or down button (F1 is normal operation, F2 when powered up relay turns on with no countdown time) Stop button turn on and off.

Thanks for this tutorial! It was very clear and it helped me understand how to use this relay. The written instructions that come with the board are super unclear, so this video was quite helpful.

[@johnathanmyers7033]

Thank you thank you thank you! I have no experience working with timer relays and as is the case with most small electrical components you can order online the instructions are poorly translated or there are none at all. The available instructions for this particular timer are notoriously challenging to understand and I gave up trying to figure out how to use it months ago. Now after watching your tutorial I can finally use it.

[@airsoftjunkie5592]

Thank you very much for this awesome video. Just received this in the mail, but had no idea how to program it with no instructions. If you ever do another one, it'd be very helpful to hook something up to the NC or NO side, to demonstrate the on/off function, like a light or fan or something.

[@mpjaonline]

Depends on your sensor if it has an adjustable set point (on-off) and a transistor output to act like the switch I used. Plus a separate power source for the delay timer 6-30Vdc. Thank You

Great demonstration, thanks. I'm using one for an alarm system where I use a trip wire attached to a pull pin that operates a micro switch to send a 12 volt signal to trigger the board and sending an operating voltage to sirens, lights and GSM dialer. Now, here's the thing, It works most times but occasionally does not and I have a theory that the time length of the signal, on occasions, may not be long enough. A trip event pulls the pin out super quick and, once pulled, the micro switch instantly returns to its normally open state. I suspect that if the micro switch closed circuit condition is only in the order of milliseconds, it may not satisfy the boards signal parameters. What do you think? Ps. I have just modified the micro switch assembly to remain closed circuit after activating, until reset, so I am testing a few more times to check my theory out.

[@Hotshotter3000]

This is really good. But I got some questions. Can you use a 9 volt battery or other batteries to power it? Do you have any videos on the wiring? I am mildly confused with the ground cable. Does it need it? I want to make sure I wire it with the trigger and the battery and everything. I'm kinda new to electronics and I just built very simple things.

[@harishmadhu5444]

This explanation was easy to understand. Thank you very much.

[@plasticelectrics]

i want to like this upload twice.... just perfect thankyou

[@walthodgson5780]

You do have to have an external trigger voltage. Simply using a switch doesn't work. When using USB power there's a 3.2vdc across the power terminals but it's not enough to use as trigger voltage. As such I think USB power is only really useful if you are using P3-1 or 3-2.

Thanks for your efforts and sharing 👍🇬🇧 I was hoping to see this switch polarity also, with option to set voltage and amperage. If you know of a device please let me know

[@thisisyourtransmission]

can this be hooked up with a motion sensor and a nine volt battery supply?

[@mpjaonline]

Yes it will work with a 9V battery but depending on the current draw of the PIR and how often it is triggered the battery would last less then a day.

[@thisisyourtransmission]

@@mpjaonline alright, what does PIR mean?

[@mpjaonline]

@@thisisyourtransmission Passive infrared

[@exgenica]

The "standby" current requirement is 20mA, and the "Relay Energized" requirement is 60mA per the datasheet on mpjaonline's website. So a typical "9Volt" battery wouldn't last long. Even a high-capacity brand new fully charged lithium-ion "9V" form-factor battery only has about 800mAh capacity. So if the board was in "standby" ALL the time, the lithium battery would last about 800mAh/20mA=40 hours...less than 2 days. (note: a lithium "9V" battery is actually a maximum of 8.4Volts and can be used down to about 6.0V)

[@thisisyourtransmission]

[@Nando_]

nice! I have an old car (brasilian pickup Chevrolet Montana, same as Opel Corsa C) and setting ignition on position 1 doesn't turn the ACC on (it turns on only when holding the key pressed in) for now the ACC IN signal for my Android headunit is coming from the ignition 2 position, so it only works when my dash is on, whith all the engine systems, with engine running or not I belive I can use this module setted on program 4 to allow my headunit to keep working for 30 minutes after I turn ignition off also I can cut power for the module when locking the car thanks for your video!

[@kishoresoni4055]

Sir you had not shown us how you connected Dc power cable to the circuit clearly. How trigger is connected to which terminals.please do so.

[@aakoksal]

Great video. I wonder if NC is closed when timer is at "Off" cycle. As an example, can I run one motor when timer is "On" and run another motor when timer is "Off"?

[@mpjaonline]

Yes the relay output has a normally open and a normally closed contact.

[@exgenica]

I'm assuming it is a "standard" break-before-make relay? Not trying to be a pain, just being sure on the spec.

[@ozarktreasures8044]

Well done and informative. Thanks.

[@zachroach9672]

Thanks for the video, helped me understand the trigger function. Can anyone recommend a 2-channel version of this? I want to power 2 circuits sequentially, then have an off cycle. Currently using 2 of these with the first's NC triggering the 2nd when the first closes, but thats a lot of wires =/

[@rustipaul7427]

I have problems with this board regarding debouncing of the pushbutton. Did you debouced the switch? I'm using a wall push button to start a fan in mode 1.3 and I have double triggering sometimes.

Thanks so much. Question: what happens if I want to display 20 minutes counting down ?(visualizing the minutes)

[@vicomedia1]

My unit only counts up -not down-is there an undocumented setting? I have looked all over!

[@MrResidentRob]

mine is the same but seems no answer @mpjaonline please advise us. Timer going up means power removed to activate relay which is ok for me as I'm using a standard pir which is a normally closed circuit to activate my stair lighting but if I use pressure mats they are normally open signals which will not work for this. Other than that this is a great module for various projects

Hi, I am making an exhaust system for my mushroom grow room. I want to use P3.2 in a loop in a way that after ever 45 minutes the exhaust fan turns on automatically for 15 minutes. I want this system to run on a 24/7 basis. Can you please help me with the following; 1) I am using the USP socket to provide power, so How to set up the wiring for the fan? 2) Please confirm if using P3.2 in a loop is the correct program setting? Thank you

[@mpjaonline]

1) Here is a link on how to connect an AC motor to the board, same principle as an AC fan www.mpja.com//download/35238outout.jpg 2) P3.2 looks like the correct program but before “going live” let the timer run on your desk for a few cycles or days to make sure it is doing what you want. Remember this board is not weather proof you must protect it from condensing humidity. Good Luck

[@N4Nai]

@@mpjaonline thank you for your response and feedback. Just a follow up question, do I need a trigger of some sort to start the motor?

I'm looking to buy this with the black relay. They also do a double relay vs. I would like to know, if i get the 24V dc input version. Can i wire 24V dc in parallel to the trigger port. Does it have a memory? In other worlds i would like to power it up and it automatically counts down the pre-programmed time till the relay switches? I have a large DC amplified speaker, i wish to add speaker delay protection in series with one of the speaker wires, one unit for treble and one for bass. I would use the double vs. but they only come with the 10A relay.

[@mschaffer2826]

Thank you for the video. Is there a way to have it start the relay when the switch goes from closed to open?

[@SwissFrogGuy]

Thank you very much for this video. I am trying to use programming mode P3.2 (OFF and ON in a cycle, without trigger). However, it always starts in OFF mode. I need it to start ON, then OFF (I am using the relay with a separate timer that has a minimum period of one minute. I need the relay to limit this to, say, 10 seconds. This way, I can set the main timer to power up the relay, and the relay stays on for 10 secs, then shuts off). As it is, I get a mode flashing for a few secs on power-up, then it starts the loop in OFF. The loop works OK, but all this delay at startup is frustrating. Any way to set P3.2 to start in the ON position, no off? There are no instructions. Thanks!

[@wickummalinda5127]

I'm on P-3.2 mode with Open 10s, close 3s and loop = 3. what my problem is, like at 10:40 it does not energize the relay, and it waits until end of P-3.2 blink to energize the relay. there's about 2 sec delay. how can i program this to overcome the issue ?

[@waynebagnall3611]

Very helpful and easy to understand. 👍

[@1stFlyingeagle]

Can this timer be used for a freezer door left open for say 5 minutes then ring the alarm. And if door is closed within set time and door is then closed timer resets. No Pizzo buzzer noise. Trying to make safety for the freezer door. an open door led light comes on. What I want is if the door is not closed in a set amount of time the timer then would go off and send power to the Pizzo buzzer.

[@bluegizmo1983]

Hey I know this is an old video but I'm hoping you can answer a question about this device... Does it remember the mode and time settings if all power is removed from the device? I.e. when it's hooked up to power next time, is it still in the previously used mode and time delay?

[@randycass9807]

I have the same question, any idea

[@randycass9807]

It remembers the mode but you have to push the stop button, is there a way to not do that? So it's always ready to go and power comes back on bypassing the stop on off button

[@IMT-AIJ]

I have a question, when using the P31, infinite loop with time on and time off, is there any posibility to override that, one time off and leave a bit longer on and then continue the normal loop? I saw the different options but I didn't see any that does exactly that. Thanks so much for your help and your great videos!!

[@KashifJarwar]

Thank You so much for detailed Explanation. 👍

[@GabrielSilverman]

Hello! I have this unit and your video has been extremely helpful however I'm finding that program P2 delays the relay as expected and then turns it on (LED lights up) HOWEVER if you press the trigger while the relay is on, the program starts over. In your example, the trigger starts the program but then is ignored if it is triggered again while the relay is open? I also found that my counter is counting UP, not DOWN like yours. Thoughts?

[@LM-fq3ot]

Thank you very much for your explanations. 🙂👍

[@bertodiy]

clear and excellent tutorial! thank you sir 😍

[@christopherowens2635]

You did demonstrate that even if the power was turned off, the relay module still remembers the last setting you set it to. Now, my question is..will the relay module still remember the last settings if I unplugged the battery? Or does the battery need to be connected to the relay at all times for the relay to remember the last setting? Hope I make sense to you.

Thanks for explanations. I've a unit that entered into a weird status. Now all modes works reversed. P1.1 for instance the relay stay on always until trigger, switch off for OP seconds and switch on again and stay so. The remaining modes also behave like that. Relay is on as soon as circuit is power on, and cycles play inverted. Relay switch off on the normally active OP seconds. Anybody knows how to exit this? There is no reset to factory, so.. no way out.

There are several manufactures with different programing. This is how the version we sell operates. As for the display going dim 12v 2amp is more than enough to power it.
