DC 12V Timer Module Adjustable Timer Delay Turn Off Module Timing Relay Time Switch 1~10sec

This thing works great, I have suggestions for wiring below to make it more clear. This thing works perfectly.I am using it to convert a Door Unlock signal on a vehicle, to send a timed power source to a higher amperage timer (havvis) which requires the ign source to last approximately 5 seconds. That timer controls a wheelchair ramp which is drawing too much power when the ignition is off. (thanks Freedom Motors)Vdc + is power,Gnd is ground.Com is the wire source of which type you want to send, Ie, Ground it if you want to send ground, Power if you want to send power.CK on the board is Normally opened circuit. (When you trip the momentary, it activates)CB on the board is Normally Closed Circuit. (Will turn OFF when momentary is applied for timed period)

works fine just as advertised however i only gave it 2 stars for easy to install because the terminal for CK,COM ,CB will only accept a very small wire gauge less than 22 gauge you would expect it to take a larger gauge since its rated for 10 amps , otherwise the unit is well made crimping a pin connector on to the load wires helps to secure wires to connector

Very easy to hook up but doesn't work properly. I ordered this as a delay timer and the first time the button was pushed it worked perfectly, the next time it actuated and just stayed on until the power was pulled. I returned it and received a second one that actuated and never shut off from the start. I would not recommend this.

UPDATE: Literally 2 minutes after my review I figured out that I needed to put a direct jumper from VCC to COM. It now works.Connected 12v to VCC and Ground to GND on the Input and then Connected Ground to COM and 12v input to a valve on CB. Applied power and LED on board lit up. Pressed button, second LED lit up. No voltage output. Switched to CB with same result. I connected a multimeter to CK COM CB with no voltage output after second LED is lit.If anyone knows what is going on, please let me know. I was expecting 12v on output, the Relay seems to be working (clicking), but no voltage on either CK or CB.

Works as it should

Took a little while for me to figure out how to wire it but that's normal for a beginner.

On the first look it works as advertised. But using it incorporated with other equipment it was discovered that the push button is not triggering just one time event it stays on for ever until the button is released.Second if you turn the timing from one end to the other end and trigger it on one end of the adjustment, the board locks up and is not recovering
