This board doesn't include a 12-volt relay. The specifications say it should connect 0.5A. My relays are 1.2W (0.1A). And they don't work. When I command one relay to turn on, it doesn't turn on and turns off. I disconnect the wires from the relay, and there's voltage on the wires. When I connect the wires to the relay, the output on the board goes out.
It's strange that when the output is off, the LED on the board lights up, but when it's on, it turns off.
