For those looking for infinite ON-OFF-ON-OFF cycle without needing a trigger signal, look at 11:48 for program number 3. NOTE: 1. When your are setting the time in program 3, if you set the time "OFF' first (by setting the time while it's in off mode), then, it will also START in the 'off' mode every time you power it up. 2. If you set the "ON" time FIRST, then (by setting the time while it's in "ON" mode), then, it will always start in "ON" mode every time you power it up.

Thankyou for your video i had just bought the relay but it came with no instructions but after seeing you video it has made the operation so easy Thankyou

[codyrussell]

Thank you when I ordered this same product it only gave me a diagram for using the same battery for the timer and a device which is not what I need and it wasn't working. Im doing the same thing only with a fan, your advice made it work perfectly!

[yevgeniyatunitskiy]

This is exactly what I looking for. Thank you very much. Now I need to start wiring. Yevgeniya

Nice explanation. I had procured this PCB board it's cheap and best for delay timer automation.
For more durability of pcb you can give input power and trigger signal both in 5 vdc instead of giving 12 vdc. Reason is there is no heatsink attached with voltage regulator ic which is converting 12 v into 5 v. If we apply 12 v input then excess heat will damage the voltage regulator IC. Input Upto 6 v 0.5A max will increase the durability and stability of this board even if it is used for continuous operations 24x7.
Relay build quality is very nice it can withstand more than in household voltage and current ratings. No issue in operating heavy loads through relay.
One good protection is provided through opto couplers ics for reverse bias protection and reverse current flow protection. Overall I can say it's a industrial standard design.

Very details explaining for this product.. now I'm understanding how its work.. thank you

[gemful]

This helped me a lot. Thank you. Have a different timer module. 4 digits. 12vdc input without trigger and NCNOCom out. Same functionality. Searched everywhere on how to change the timing range. Glad I saw this video. 😍

Brilliant explanation. Without your help would never have understood the detailed instructions as translated. I am using it in P6 to power a DPDT relay to reverse current for a model tram shuttle (auto back and forth). In test with LEDS (in parallel with reverse polarity) it flips/reverses current well to the exact time. However, the screen goes blank after the first switch, while the current reversal and timer continue to work. Disconnect the DPDT then apply power and the display works fine. I have tried diodes, separate power supply etc., but it seems to not like the surge required to start the DPDT coil or the surge when DPDT coil power is cut.

[kareems]

Thank you so much, it would have take me long time to figure out the programming part. You made it so easy. Really appreciate.

[KAVIAN_HZ]

thanks is this any way to disable the delay time I just want to use once per use I want to use the timer for turning on and not using the cycle?

[TheFalconJetDriver]

Outstanding explanation of the abilities and practical uses, thank you so much for taking the time to share your knowledge of this device.
I will be using this to control my dust collection system in my wood shop. I will use P-4 to be a delay to run my blower motor off after a few seconds after I have turned off the tool that started the DC system. This module will turn on a solid state relay since my DC system draws more that 10 amps.
As for the trigger part of the project I will use a current tap to trigger this module.

i have downloaded many of your videos so i can watch while offline

[Lateru]

Great tutorial. I'm going to use this for a delay power off of my car stereo, which is older and doesn't have the delayed time off found in newer cars.
P-2 program seems to be the one to use, just set the off trigger to zero and the time I want delayed to whatever I want. Thanks again.

[michaeldaly]

P-2 seems to work differently for the 4 digit unit
ie P-2 can be used to close a circuit for a specified time immediately after powering up this handy little unit

[Yet_Another_Steve]

Fantastic video, thank you very much for the time you took to explain this with your clear & concise instructions. In P1 mode can I use the trigger to turn the light on and off with one momentary switch, or alternatively can I use the trigger to turn it on and remove power altogether to reset it to off with two momentary switches? I want to turn on and then turn off the light, but if the light is left on it should turn off automatically after a set time (canopy lights in a pickup bed). Thanks in anticipation.

[charlesdean]

Oh thanks a lot! Your video saves me some time figuring this out because this module did not came with instruction manual when i bought it from China.

[thomasgena]

Excellent video instruction. Thank you!

[tjtravelsandadventures]

Exactly what I was looking for. Thank you so much for the very detailed description that made my decision on buying a few for my projects.

I ended up using one of these and it triggers but the dc motor im connecting on the right side doesn't spin at all. What I have going on is a 9v battery connected into a bread board then a wire coming from the power of the 9v on the bread board to the top left and a wire connected to the ground of the 9v on the battery going to the bottom left and a wire in the middle left that triggers from a signal from a push button to the middle left. (signal works because countdown enables on this module when the button is pressed) and on the right side i've tried 1 wire in the breadboard ground from the 9v from the dc motor and the other wire of the dc motor in the middle right or even top right of the module with a power wire coming from the 9v on the breadboard on the bottom right but it doesn't ever trigger the dc motor like it's not getting any power. I've tried taking the wire from the bottom right and touching the middle right where the wire from the dc motor is connected and it does not trigger. Anyone have any thoughts on this? Thanks!

[dirtchurch]

I really like this timer. Can you help me on how i would install a counter.
For example i need to record how many times the light turns on.
Thanks
