1pc DC 12V/24V Adjustable Cycle Times Switch Module Delay On/Off Timer Delay Switch Module 6 Types Optional (DC12V 0-120mins)

I have hanging plants on a pergola that need frequent watering. I ran the hoses and installed the small sprinkler heads but wanted a “brain dead” way to operate the system. Enter this board. I tucked the board away where it’s protected from the weather. I installed a big green momentary push-button in one of the columns. I then set the timer’s pots so that when the button is pushed the sprinkler is activated for 4.5 minutes. Push the button and walk away. Never have to worry about over watering. The instructions are very clear with the exception of setting the timers but there’s an led on the board to show relay status making adjusting by trial & error painless. It’s a great item. Highly recommended.

I used this with a 12v power supply, magnetic switch (as trigger) and red 12 v led trailer markers to make a parking assist for a friend. Mounted a magnet to a length of 1/2 inch pvc full of sand which moved magnet past switch triggering timer to turn on leds for 30 seconds. Stop the car. Backup to tennis ball on string.Only issue is adjusting the time. Even on t/10 the pot is very sensitive and if you need a specific time it will take some doing. Also the mounting hole on the board are very small and I just zip tied it to a strip of plastic and mounted that. All my spare computer hardware stand offs didn’t fit.

Everything works exactly as advertised. I had to add some peripheral hardware to make it do what I wanted. (I really would like to find some little turn key timer module that has a retriggerable function), but this will do in a pinch. This is still a nicely designed and assembled product at a great price.

I clicked on the 12 volt option but something must have gone wrong. Not sure if it was a computer glitch or if I made a mistake. Their product description is unclear because it states the relay is 12/24 volts. Because of this I did not catch the mistake. I really like the relay's design and I wish I could use the ones I got. Order carefully. The 24 volt relays do not work on 12 volts. There are more expensive cycle relays I've used that have digital display of the time. They use more power and are much more cumbersome to adjust because you have to adjust every digit individually. With these you simply turn a screw one way for more time the other way for less. One screw for the on time and another for the off time. So simple.

I got this timing circuit for my son's volcano school project. Works well, but I gave it 3 stars because its a bit difficult to adjust the timing, I finally set it to what I needed - 20mins, but it was all trial and error.

Great price and fast shipping. Went through programming but only stayed ON until timer counted down. Not able to program OFF cycle. Went over numerous times. Will use for some other project.

Very handy little circuit to have.Takes a bit on the workbench to dial things in but this timer circuit proved to be very useful in setting up a RV hot water recirculating system

Set to turn on lights for ABOUT 5 minutes. Timing is far from precise.

The product functions very well.Easy to understand the features.The wires hooked to the connectors are extremely thin.Need to check and recheck that there's no break once connected/welded

This is a nice little timer. I am using it to turn off a work light in my service truck in case I forget. The wiring diagram pictured on Amazon for the DC12V 0-120 min (Labelled Wiring 2 Reference) shows the load connected to the LOAD and NO. I believe the NC, COM, and NO are just what we call dry contacts. The correct diagram is shown with some of the other timer choices as Wiring 1 Reference. Perhaps I missing something but Wiring 2 Reference does not look like it will work, nor did it work when I tried it. The tiny adjustment ON dial starts at 4 O'clock for zero increasing counter clockwise to about 8 O'clock for max (or in my case 120 min). The 3 O'clock position gave me an on time of 9 minutes. Hope that helps.

I didn’t get to try it because the polarity was reversed (my mistake) and I fried it. The switch did not cycle on and off after that. Make sure you have the polarity correct. Otherwise, it was just what I needed.

Wanting to use this as an automatic off-timer for my pickup cargo light.Eg, push button on, then auto off after 5 mins.I've got the 12v +/- inputs to the module.I've got my trigger switch working.Still getting the off-timer set to shut off at 5 mins but I'll get it adjusted eventually.But how do connect my LED lights + and - 12v?
