6 Channel 12V Relay Module with Optocoupler Isolation (6-Channel Opto-Isolated Relay Board)

The 6 Channel 12V Relay Module with Optocoupler Isolation is a reliable switching interface board designed to control six independent AC or DC loads using low-voltage control signals. Each relay channel features optocoupler isolation to electrically separate the control circuit from the relay circuit, improving noise immunity and protecting microcontrollers from voltage spikes. Operating from a 12V DC supply, the module is compatible with Arduino, ESP32, STM32, Raspberry Pi (with appropriate interfacing), PLCs, and other embedded control systems. It is ideal for industrial automation, home automation, robotics, power control, and IoT applications.
