🕛 Powerful Timer Relay, DROK Time Delay Relay DC 5V 12V 24V with LCD Display, Micro USB 5V Support – Delay Controller Board Delay-off Cycle Timer 0.01s-9999mins Trigger Delay Switching Relay Module Review

I got one of these to see if it would work with my Hikvision camera's signal output and it works. I can now use this relay to activate a 110v light when I receive a movement signal, intruder alarm or line crossing. You can enable all or one of them in your camera software. I chose program #2 for my purpose. Now the camera turns on the light when it receives an alarm and stays on for the time I programmed into the relay. It then disconnects and waits for another trigger. If you don't want the…

My solution to this was to start the circuit with a battery fuse and then connect it to the DROK timer relay. It is not possible to get power directly with the key in the accessory position without going through the TIPM. The ignition switch itself is…

I have a small pump that empties the collection tank. I installed a simple float switch, but the tank is small enough that the water level rises sufficiently from the backflow created when the pump is turned off. I put a check valve on the line, which made it better, but still stopped the pump from running all the time. Not good for the pump and not achieving anything. I installed a DROK Time Delay Controller and was initially disappointed as all program modes require the switch to be turned…
