Description
Unit Relay is a relay unit capable of controlling the on/off state of circuits at levels of DC 3A / 30V or AC 3A / 220V. It essentially functions as an automatic switch that uses a small current to control a larger current. Therefore, it plays a role in automatic regulation, safety protection, and circuit switching in electrical circuits. The unit provides three pins: ON, OFF, and COM. By programming the GPIO to output high or low levels, the common terminal COM can be connected to either ON or OFF.
