5V 4-Channel Relay Module with Optocoupler
0·Generic / Compatible·RS095
The 5V 4-Channel Relay Module with Optocoupler allows a microcontroller to independently control up to four electrical loads. Each channel provides NO, NC and COM contacts, making the module useful for switching lamps, fans, pumps, solenoid valves and other AC/DC loads. KSP ELECTRONICS Opto-isolated versions provide electrical isolation between the control inputs and relay section, making them popular for Arduino, ESP32, ESP8266, Raspberry Pi, robotics and home-automation projects.
