The 16-Channel 5V Relay Board Expansion Module is a high-performance switching solution designed for controlling multiple AC and DC appliances from a single microcontroller or development board. Featuring 16 independent relay channels with built-in optocoupler isolation, this module provides reliable electrical isolation between the control circuitry and high-voltage loads, ensuring enhanced safety and stable operation.
Each relay channel can be independently controlled, making the module ideal for automation systems, industrial control equipment, smart home projects, robotics, IoT applications, and other embedded systems. Integrated LED status indicators allow real-time monitoring of relay operation, simplifying installation and troubleshooting.
