5V 2 Channel Relay Module with Optocoupler
The 5V 2 Channel Relay Module with Optocoupler is a reliable interface board designed for switching two independent high voltage loads using low voltage control signals. It features optocoupler isolation to protect the controlling microcontroller from voltage spikes and electrical noise. The module is compatible with 5V logic and works seamlessly with Arduino, Raspberry Pi (with level shifting), ESP boards, and other microcontroller platforms.
Ideal for home automation, robotics, and industrial control projects, this relay module allows safe switching of high power devices such as motors, lights, and appliances. The onboard indicator LEDs provide visual status of each relay channel, and the screw terminal connectors make wiring simple and secure.
