Home Automation: How to use 7 Program 0.1s to 9999 minutes Relay Timer XY-LJ02

[@betafoofoo270]

Absolutely excellent tutorial, thanks for sharing this .

[@stabbb1299]

Excellent tutorial! I purchased this item on Amazon for the purpose of opening a door latch with a 3-second 12v pulse once every 24 hours. From your description either P5 or P6 will do this after an initial trigger using 1440 minutes as my loop time. Please tell me I'm correct. The purpose for this is to open the door on my chicken coop every morning at 8AM... Thanks!

[@abhishekkarkera1]

17:11 I have a situation where the circuit should close for 1 sec once a day without giving a external signal so the program should be like cl:1 sec op:1440min loop : infinity , is this possible?

[@dvoz9023]

I would love to use the OP without trigger button, but like program 6. only not the CL with it. I'm building a battery operated light and want to shut it off automatically after 2 hours, or manually with a main switch. When switching on the light again it should start counting again for 60 minutes.

[@luboskladan3164]

I hope you can help me. I purchased exactly this model of timer but it did not come with instructions on how to set it up. I do not have a push button. I have a product switch which controls a solenoid gate. The gate in normal position is closed. I want this gate to open 1/2 a second after the product switch was triggered by the product and the gate to close once the product passes completely by the product switch. How do do the setup? Thanks

[@richlawrence4160]

Brilliant explanation, would have not worked it out myself from the descriptions in the product. Thanks heaps, an excellent video. I am using this for a model tram shuttle (automatic back and forth) via a DPDT relay to reverse the current (change tram direction). Found a problem that the screen went blank (still lit but no characters - not sleep) after the first relay switch, although the system worked OK running the reverse current circuit. A) read the manual, in a shared power supply, the load MUST be on the negative side - not the positive side. B) always place a diode across the power /activation 'coil' circuit of the relay (the correct polarity of course). Problem fixed.

[@suzannehansen2828]

I have a deer feeder. This consists of a feed bin and an electric motor-generated feed disperser. The unit is powered by a solar panel. A "Moultrie timer" is introduced into the circuit, allowing programmable feed duration and timing intervals. This timer is unfortunately limited to feed intervals in whole seconds. I want to refine feeding intervals to fractions of a second, and I stumbled upon the XY-LJ02 as a solution. I tested the device (with an on/off switch in place of the timer), setting it to P4 mode and a CL of 0.5 seconds then OP of 2.0 seconds and then turn off. On the bench it energized the load as intended. But when I took the prewired device to the actual feeder, it didn't work! I'm concerned the problem is with my pre-wiring of the XY-LJ02. You mentioned in this tutorial changing the wiring on the left side of the device in the event of using an "external source" in lieu of a push button switch. I did not understand this explanation, it went too quick for me. HOW WOULD YOU WIRE THE XY-LJ02 FOR THIS FEEDER? Stephen Hansen

[@robojax]

I explain everything this module does demonstrate it. Now the scenario for each project might be different but you would have to use it withing the capability of this module. Perhaps watch it more than once to see how it functions.

[@Super_Mario_Esq]

Good job, great tutorial. Now I know it fits my need, and the mode I should choose is P6 --- loop a program many times and if there is a power outage, it'll restart. Thank you.

[@sycobob8085]

Is there a way to program it so that it only counts down if the trigger is pushed? If the trigger is released I want the count down to stop. In P4. I’m using this to close a door. Once the door is full open it pushes and holds the trigger. It will count down to activate relay to close the door. If someone closes the door early the door will open at the end of count down and start the cycle over.

[@robojax]

All possible functions have been explained. If you watched the video fully and did not find what you were looking for, then it can’t do it. Please watch.

[@AmericaAndAllies]

In 'hibernation' or 'sleep mode' (with the display off) do we know the milliamp current draw with the display off? The manual says 'static current' at 15ma. Do we know if that is when the display is off?

[@robojax]

Yes.

[@chrizki456]

The countdown timer is one feature I’ve been looking for. The other models count up. Can you suggest one that has an “add” feature to the timer every time the trigger is hit? So if it starts at 5 seconds then if I hit the trigger it adds another 5 seconds to the current time counting down.

[@monkeyvideo1029]

Thank you for the detailed explanation! This helped me better understand how to work the one I bought. I specifically purchased mine as an external watchdog timer for my home automation and security DVR computer. The intent was to have my HomeSeer controlled Arduino send a pulse to this timing module to keep resetting the clock. If it didn't reset (PC locked up) the relay would engage the PC reset switch. Unfortunately I can only configure this module to work the opposite. Using P7 the relay is always engaged and if the input is triggered (pulse from Arduino) before CL timeout then the relay will stay engaged. If PC locks up and and stops triggering the Arduino then CL will timeout and cause the relay to disengage, which could trigger the PC reset switch. Ideally I do not want the relay engaged 99% of the time. Instead I would like to keep the relay off with ongoing trigger timer resets and if there is not a reset (PC locked up) then engage the relay for 1 sec to reset PC. I have tried every combination I can think of with this module but don't think it is possible. Did I miss a setting? Do you have any other suggestions? Thanks in advance for any help.

[@robojax]

you are welcome. check the wires connected to the relay to revers the affect.

[@Drrrre]

Should there be a fuse to protect the power input and/or trigger? Rating?

[@robojax]

The fuse should be in your load or device. Usually the device you are controlling has protection. This is just extra switch to turn it off or on.

[@Drrrre]

@@robojax thank you, but I was thinking about how to protect the product from a spike or something so it doesn’t get burned.

P4 looks like what I need, but instead of momentary switch I want it to begin as soon as power is supplied to the relay board. Can I just wire power to the trigger? Does it matter if the trigger remains on?

[@waybassdroids]

If i hold trigger at P1, would it be restart the timer or not?

[@GlassRF]

All of these time functions are time off delays and loops are AFTER being triggered. These boards should have been built with programmable time ON delay functions when triggered in all modes to be truly flexible...

[@tanyathorvilson]

I'm building a hopper feeder. I want to trigger it, have it turn on and off rapidly 3 times and then stop until it is triggered again. Is that possible?

[@shirkeyturkey8191]

In the P6 program will if the setting was " on time (OP) 1.5sec, off time (CL) 30sec, and loop (LP) set to 1" and the switch was activated for a total of 30 seconds, the relay would only turn on for the 1.5 seconds correct?

[@AmericaAndAllies]

For mode P6, there is no trigger. If you apply power to the timer board, it will act as you described, one time. The only way to cycle again in this mode is to remove power and re-apply power and it will run the P6 mode again automatically, one more time. If you set the loop count to '----' that is infinite count, and it will repeat the cycle over and over until you remove power.

[@ChopperCharles]

I need to actuate a solenoid 1 or 2 seconds after the relay receives power. It needs to actuate for 0.5 seconds, to actuate a momentary button. It then needs to shut off and not repeat unless powered down and then powered back up again. Can this relay do that?

[@Jim-cr5td]

I have a pump that is currently turned on by a pushbutton switch. I want to turn it on with a flow switch but then delay it from turning on again for 45 minutes before the flow switch can turn it on again. Will I be able to do this using P5?

I've explained all features in the best possible way. Load is load if you respect the power rating. I don't remember anything about this module now as I have over 450 videos. if you are convinced from the video that it can be done, then you should be able to use. May be watch the features more than once to know it better.

Before I put the relay timer on, I just had the flow switch triggering the pump but for some reason, the pump would turn back on every few minutes. This is working perfectly now that I have the relay timer installed. Thanks so much for your instructional video.

Can this device be used to latch an intermittent pulse power connection? I have a 12v dc current that turns my turn signals off and on in my vehicle. The time between off and on is 2 seconds. So the turn signals flash- rest- flash until the turn signal is moved to the neutral position. I want to use the left and right turn signal power lines to power my blind spot video cameras. If I hooked up my cameras right now the video would loop off and on until I finished my turn. I want the video to be constant until the turn signal trigger is moved to neutral. Will this device do that?

[@anthonystrohmayer9191]

@@robojax I watched your video twice and I'm confused. Does this timer relay convert momentary to latch? I will not be connecting a constant power supply to this device. It will get a power trigger which is momentary. It will be a looping source until I manually shut it off. It is DC 12v. When I move my switch to on it will create a looping momentary power trigger every 2 seconds. In other words it is on-off-on-off and so on. I read that a timer relay can turn momentary power to latching until the trigger is removed. Where in your video covers this? Thankyou

[@jamesmoran8907]

Great Video. I want to build an auto garage door closer as we keep coming home and finding the door wide open. The problem is that every time the door motor receives a signal it will stop, and on the next signal reverse. This means we need a loop and then stop the loop once it actually closes. So I need to be able to have a delay of a few minutes once the reed switch activates, run a one second signal (to activate the door) and close it. Wait a minute to give it time to close, then if the reed switch remains open close the relay again for one second so the door activates again. This covers all options and the door will defiantly close. If we just have one signal then we might just end up opening it all the way when myself and the girlfriend both push the buttons when we leave.I am thinking P5 will do this.

this is a DIY (do it yourself) module and you need to know a little about electronics. Trigger means a a voltage comes for a short period of time at the input of this module. or you apply some voltage at the input so it starts working like START button. The difference is that you need a pules (which is a voltage for a short moment).

Has anyone tried to determine what the 5 pins to the right of the serial port pins are? I think that two of them, GND and 5V are wired to the USB connector, one is a 'disable' line (5v weak pull-up), and the other two pins remain a mystery. If you disable by pulling 'disable' to ground, then release, the display will restart but a button press is required to resume operation. That would be like tapping stop when it is running. Perhaps timing is necessary to control enable/disable. I am not sure. If anyone has experience using the serial lines, observations would be appreciated.

[@robojax]

Those are for the manufacturer to upload the firmware. Not for the user.

Hi Robojax Thanks for the learning video I am searching for Something like P5 But starts with the relay off on off And finish with on can you help me please thanks

[@robojax]

Hi, you are welcome. I don't have the module test it now. I don't know where I put it. But Remember you can connect your load or bulb to the Common and NC (normally close). I have shown it with Common and NO (normally Open), if you connect to Common and NC, the operation will be the opposite. Meaning if the module was turning something ON from OFF state, it will turn something OFF from ON state.

relay is a switch. I don't know how to the machine function. but if you have to learn that machine, then use this module to turn it ON/OFF with specific timing.

Great tutorial RJ, I watched with great interest as I need 80 timers with with a 'Delay On' time of 4320 hours (180 days), for use as service interval reminders to turn on a 'Service Required' led pilot; can you tell me if this this Drok timer be modified to do what I want or do you know of another suitable timer? Thanks BJ

I bought 4 of these and after 4 hours i figured out how P6 worked and how to change the decimal. Also i found if LP IS LP 0000 MEANS CONTINUOUS CYCLES. Is there an instruction sheet that i can down load for this timer? If so where? Also how can i program this timer using USB and what application do i use and what baud rate?

[@robojax]

hey, there no information to control it via pC

programmable 3 relay logic module, please review this modules

[@robojax]

I have done a video for dual relay which would have been the best solution to so many things and no one has watched it. This might be the same only few might need it.

[@aryeguetta8592]

Great tutorial - And you have done that again! :) I just ordered my XY-LJ02 Relay Module from AliExpress. The main thing that i wanted to try is the Serial Commands using Rx and Tx - Since I am planning to set the relay far from the MCU and I don't want to set a new program from the module all the time - I want to be able to set the program itself and also If I should use a loop then gfive a count for it and set On and Off time for each one of the 7 Programs - and all of this I want to see how it can be done from the Rx and Tx - assuming that I will connect it directly to my MCU Rx and Tx as well. I can also be able to set more then one board from the Arduino (or any other MCU I choose) using a different pin-set for each one - i will need to set another Rx and Tx on the Arduino, I am not sure how But this is also something I am looking forward to test Maybe using the Software serial that way I can use more then one set of Rx and Tx Communications . GREAT JOB!!! thank You.

[@robojax]

Thank you. If I saw people show interest in this module and if time permits, I will make video on that. I have 100s of other projects on my list but I am busy with full time job at a university and part time graduate studies and my family. So I have very tight schedule. Wish me luck.

[@aryeguetta8592]

@@robojax Good Luck!! :) Yes I know how it is!! same situation here. I hope you will have the time for the Serial as well - I will give it a go when the board comes. I think that it could be done and that would be great to be able to control the Relay behavior remotely.

[@joeg2577]

Great Tutorial Ahmad, can a Inductive proximity sensor(NO) be connected to act as momentary switch when using P4, if yes which one would you recommend PNP or NPN. Thank you

[@robojax]

this needs voltage as I've shown. so does not matter where it comes from. yes you can connect.

[@joeg2577]

@@robojax I have tried a PNP proximity sensor(NO) but it does not turn on relay, proximity sensor does power up

hi, could you explain how uart works on this device

[@robojax]

you are the 2nd or 3rd person asking for this. I don't see great interest to spend 1 to 2 days to learn and then spend 1 day to make video. Do online search, you may find something on it. Good luck.

Hyyy i hope everything is good. I need some help i have this project. And my goal is to control two 12v fan I have a. L298N motor driver controller I also have a. timer delay relay I also have a .elegoo uno r3 I also have a. Lcd screen 1602A And it should all be controlled by the bluetooth dsd. My goal is to be able to controlthe fans with my phone. I want to be able to set a timer on the fans and also turn it off when i want. Is there any way you can help me

[@robojax]

this is the most complex project I have seen. Each needs separate project and I have video for all of them. Search my channel and do it ONE by one and then put it together.

I'd like to see a PIR as the trigger device instead of a button switch.

I have few videos on PIR and they can be used very easily

how to wire this for low trigger ?

you will need to make external circuit to do that. Here is a circuit snipboard.io/vERWPt.jpg
