16 Channel 5V Relay Module with Optocoupler Isolation (16-Channel Opto-Isolated Relay Board)

The 16 Channel 5V Relay Module with Optocoupler Isolation is a high-capacity relay control board designed for switching multiple AC or DC electrical loads using microcontrollers, PLCs, and embedded control systems. Featuring sixteen independent relay channels with built-in optocoupler isolation, the module provides reliable electrical isolation between the control circuitry and high-power loads, ensuring safe and stable operation. Operating from a 5V DC supply, it is compatible with Arduino, ESP32, ESP8266, STM32, Raspberry Pi (with appropriate interfacing), and industrial automation controllers. The onboard LED indicators and screw terminal connections make installation and monitoring simple and convenient.
