- Operating Voltage: DC 12V; Quiescent Current: 5.5mA; Max. Operating Current: 42mA; Max. Load Voltage: terminal NC is DC 30V or AC 250V, terminal NO is DC 28V or AC 125V; Max. Load Current: 10A
- Functions: Supports on delay and off delay modes, the delay time can be adjusted from 0.1s to 1h, the delay mode and delay time can be set by shorting or opening the jumper pins and rotating the potentiometer.
- Self Protection: Built with protection against reversal diode, supports anti-reverse protection. NOTE: Please remove the jumper cap of S5 when controlling AC current or DC current voltages other than 12V, otherwise the module will be burned or will not work properly.
- Applications: This module works as a switch with time delay on and off function, highly recommended for automotive circuit modification, and LED lights, DC motors, pump and smart home control system.

The Pros:
– It does what it says it will. It allows you to set a timed delay for turning a power source to a load on, or off after X amount of time.
– It’s cost effective.
The Cons:
– I found that this does not work like a regular relay in the sense that I only needed to supply power and ground, and then a wire to the normally open terminal…that’s not normal. It didn’t require a power lead to the common, so that means that power was sent to the load from what would normally be tiny wires meant only to power the coil.. Alternatively, I found that I could supply ground to the one side, and power via the common and get the same result. With a mechanical coil the common and coil positive leads don’t connect. I get that this isn’t a mechanical coil, but explaining this in the instructions would have been nice.
– To tack on to the point above, the instructions are lacking. In addition to the example above, having a more detailed wiring diagram would also be extremely useful.
– The case that it comes in completely covers the module so it requires modification to be able to get wires to the terminals – this can be time consuming. It would be nice if these were already in place and I would imagine it would save material cost for the vendor.
Other Observations:
– Though the module fits nicely into the enclosure it’s not snug and will rattle around unless secured internally (I used double sided tape and hot glue) or screwing the module to the case.

I used this to control a latch that needed momentary power to function. The shortest I could set my 12V digital timer was to 1 minute. I used this module to convert that 1 minute of 12v to .5 second of 12V.
The following is probably too much info, but some times it helps to hear it explained different than the manual, which there is a link to at the bottom of the listing in PDF.
The time the switch is “active” is easily adjustable using the S1, S2, and S4 Jumpers and the dial. You can also switch the s6 and s7 jumper and make the switch delay for a period of time then turn ON after the delay, as opposed to turning on for a period of time then shutting OFF. The 12v input has to stay on the entire time the switch is being used. If you leave the S5 jumper on it will apply 12V to the center contact (group of 3 screws). The center contract “switches” between the top and bottom contacts when the relay in energized with your 12v input. If you want to switch something other than 12V. Remove the S5 jumper, this will isolate the 12V input from the 3 terminal switch. Then attach what you need switched to the terminals.

This thing is versatile. Also, if you have a brain, it’s easy to set up.

There are other boxes and other boards on Amazon or much less money each but this one came as a set and I liked it. I said this one up as a 15 minute timer so that when it was turned on it would run for 15 minutes and then automatically turn off it works perfect for that application with a little bit of wiring
AdamS –
The instructions are absolute garbage – there are definitely technical errors, missing concepts (ie. where is the S3 jumper documented? Some S1/S2 patterns are duplicated, so I expect half of them were supposed to be S3).
But it’s not too hard to figure out anyways, and once configured this has operated quite nicely. Solid hardware.

This item worked as advertised. I used it to sound a buzzer for about 5 secs when the clothes washer finished its cycle. (Its in the garage and we can’t hear it’s “bell”.) The relay and the buzzer were both 12 VDC so I found an old plug-in transformer (wall wort) rated at 12 VDC @ 300 ma. The circuit design required the relay to be energized WHEN THE WASHER IS OFF. So most of the time the relay is ON. Trouble was, the low current draw made the 12 VDC more like 19VDC. So it worked for a while but then quit. So don’t exceed 12 VDC by much or yours will quit too.
It worked well enough that I have ordered a new relay. Ethically I could not return it as I exceeded its specs. I’ll find a 12 VDC source @ 100ma.

I am using this to delay the power “ON” for a small 12v DC/20watt amp. Does not require any “stand-by” voltage to keep it active. “COM” output is + voltage (like a pass-thru) if jumpered. All configurations are done with jumpers and a variable resistor. Check your jumper settings.!. Ships in an anti-static bag and well boxed.
Cons:
Wiring instructions should show at least 2 “normal” examples for us beginners.

A great product, once I understood it. Great customer support!
