PRODUCT DETAILS

Description

RELAY is a relay unit that allows you to control the on/off state of circuits operating at the DC/3A-30V or AC/3A-220V levels. It functions as an automatic switch, where a small current controls the operation of a larger current. In electrical circuits, relays play a role in automatic regulation, safety protection, and circuit switching.

The RELAY unit provides three pins: ON, OFF, and COM. By programming the GPIO (General Purpose Input/Output) pins of your microcontroller or device to output high or low voltage levels, you can control the relay. The common terminal, COM, is connected to either the ON or OFF terminal to control the circuit's state.

RELAY units are commonly used in applications where there is a need to control higher power loads or switch between different electrical systems. By using the RELAY unit, you can automate the control of circuits and ensure the safety and efficiency of your electrical projects.
