Review on 🕒 12V Time Delay Relay Module by UCTRONICS for Enhanced Smart Home Integration, Tachograph, GPS, PLC Control, Industrial Control, Electronic Experiments, Arduino Robot by Dave Giri

I tested the block on my workbench, I am very satisfied with the work of the block. My particular use for it is quite unusual. Have you ever been driving your car somewhere and found your phone dead after parking it? But you can't charge it while shopping because your car cuts off the 12 volt supply to the USB charger to protect the car battery from being discharged. With 12V DC time delay module. I can "hot" 12V power to my USB charger for up to 3600 seconds (1 hour) and then switch the power line back to the 12V auxiliary circuit to save the car battery. That one hour charge is enough to get you back in the air until you're done charging. And if you forget to turn off the 12 volt (Hot) supply to the timer after the cycle is complete, the timer's standby current draw is so small (less than 6mA) that the car shouldn't be affected. Battery, more so than any other circuit in your car that "always" draws power from it. The power consumption when the timer is on is only 60mA, which is a small fraction of the current your device uses while charging. This current could be further reduced if the "on" LED were removed. I don't need to see mine as I mounted them in an aluminum "project box" and fused them with a one amp "spike fuse" to protect their circuitry and vehicle wiring.
