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. Features Single bus control Supports up to DC/3A-30V or AC/3A-220V Development platforms: Arduino, UIFlow (Blockly, Python) 2 x LEGO-compatible holes Includes 1 x Unit Relay 1 x HY2.0-4P Grove cable (20cm) 1 x 3.96 terminal Applications Remote control of high-power appliances such as refrigerators, air conditioners, TVs, etc. Specifications Specification Parameter Single relay power consumption 5V@40mA Coil action time 6ms Coil release time 4ms Product Size 48.0 x 24.0 x 8.0mm Product Weight 9.5g Package Size 138.0 x 93.0 x 9.0mm Gross Weight 17.1g Learn and Documents → DOCUMENTS
