16 Channel 5V Relay Module with Optocoupler – 10A Relay Board for Arduino, Raspberry Pi, PLC & Automation Projects 

The 16 Channel 5V Relay Module with Optocoupler is a high-performance relay interface board designed for controlling multiple high-voltage and high-current devices using microcontrollers such as Arduino, Raspberry Pi, ESP32, PIC, AVR, ARM, and PLC systems. The board includes 16 independent relays, allowing you to control multiple AC or DC loads at the same time.

Each relay supports switching up to 250V AC / 10A or 30V DC / 10A, making this module suitable for home automation, industrial automation, robotics, and IoT projects. The built-in optocoupler isolation protects the control circuit from electrical noise and voltage spikes, ensuring safe and stable operation.
