Description
The 12V 2-Channel Relay Module is designed for controlling high-voltage AC or DC devices using low-voltage logic signals from Arduino, ESP32, Raspberry Pi, or other microcontrollers. Each relay channel is isolated via an optocoupler to protect the control circuit. The module features onboard LEDs indicating relay activation and screw terminals for secure connections.
