2 Channel 12V Relay Module with Optocoupler – 10A Dual Relay Board for Arduino, Raspberry Pi & PLC Automation

The 2 Channel 12V Relay Module with Optocoupler is a reliable relay interface board designed to control high-voltage and high-current devices using microcontrollers such as Arduino, Raspberry Pi, ESP32, PIC, AVR, and PLC systems. It features two independent relays, allowing you to control two different AC or DC devices simultaneously.

Each relay can switch loads up to 250V AC / 10A or 30V DC / 10A, making it suitable for switching lights, motors, pumps, and other electrical appliances. The built-in optocoupler isolation protects sensitive control circuits from voltage spikes and electrical noise, ensuring stable and safe operation.
