This is 12V relay breakout board. Yet, it is kind of special because this is low level trigger 12V relay, or active low relay module. To control it , logic low, or 0V is needed. Normally it is being used together with NPN (Open drain) output sensor, e.g.:
The relay module comes with three header pins:
The relay terminals (COM, NO and NC) are brought out using screw terminals. On-board relay is rated at 10A. It can be used in many applications: controlling high voltage, high current load such as motor,. solenoid valves, lamps and AC load. It also come with 2 LEDs to indicate the status power (VCC) and status of relay.
NOTE: This is an active low device, which means logic low (0V) at pin IN will trigger the relay.
