Description

The 1-Channel Optocoupler Relay Module with Screw Terminals is a compact and convenient switching module designed for controlling electrical loads using microcontrollers and low-voltage control systems. It features an optocoupler that provides electrical isolation between the control circuit and the relay circuit, helping protect connected control electronics from electrical interference.

Both the input and output connections use screw terminals, providing secure and reliable wiring without the need for loose jumper wires. This makes the module easy to install, remove, and maintain in prototypes and permanent projects.

The single relay channel can be used to control devices such as lamps, fans, pumps, solenoid valves, motors, and other electrical loads, subject to the relay’s voltage and current ratings. It is suitable for use with Arduino, ESP32, ESP8266, and other compatible microcontroller systems.
