Description
The 4 Channel 5V Relay Board is a versatile relay module designed to control up to four electrical devices from low-voltage controllers such as Arduino, Raspberry Pi, ESP32, ESP8266, and other microcontrollers. Operating on a 5V DC control signal, it provides reliable switching for AC and DC loads in automation, robotics, IoT, and electronic control systems.
Each relay channel operates independently, allowing multiple devices to be controlled simultaneously. The board features LED status indicators, screw terminal connections, and opto-isolation (model dependent) for enhanced safety and stable operation.
Ideal for home automation, industrial control, DIY electronics, and embedded system projects, the 4 Channel 5V Relay Board offers dependable performance and simple integration with a wide range of controllers.
