6 Channel 12V Relay Module with Optocoupler Isolation | 6-Relay Board 10A for Arduino, PLC, ESP32 & Automation

6 Channel 12V Relay Module with Optocoupler Isolation | 6-Relay Board 10A for Arduino, PLC, ESP32 & Automation 

The 6 Channel 12V Relay Module with Optocoupler Isolation is a reliable switching board designed for controlling multiple electrical devices using a 12V control signal. The module includes 6 independent relays, allowing simultaneous control of different AC or DC loads in automation and industrial projects.

Each channel uses optocoupler isolation, which protects the control circuit from voltage spikes, noise, and interference, making the module suitable for PLC systems, Arduino, ESP8266, ESP32, Raspberry Pi, and other microcontrollers. The isolation improves safety and ensures stable operation in high-power switching applications.
