Very beautiful appliances
Great value for money, but I think the wiring instructions are unclear, and possibly incorrect. COM pin is the relay driver ground - not the opto isolator return. I think you have to connect the +12V supply to the pin marked Vcc, 0V to COM. Remove the jumper, then the isolated drive signal goes between IN (+ve) and GND
Nice 1 relay module
it works perfect I measured a 3mA current on the 5V signal from my arduino which is nice. it's a bit noisy when switching but that doesnt bother me for my application
The mentioned "5V IN" in the description led me to believe that it would be controllable by 5V, which is wrong. It's a 12V devices, as the title suggests
NO PROBLEM !!!!!!!!!
Fast delivery. works well
