6 Channel 5V Relay Module with Optocoupler
The 6 Channel 5V Relay Module is a versatile switching board designed for controlling high-voltage AC and DC devices using low-voltage microcontrollers such as Arduino, ESP32, ESP8266, Raspberry Pi, STM32, and other development boards. With six independent relay channels, it allows multiple devices to be controlled simultaneously, making it ideal for home automation, industrial control, robotics, IoT projects, and smart appliance applications. Most modules support loads up to 10A at 250V AC or 10A at 30V DC and feature optocoupler isolation for improved safety and protection.
