3V 1 Channel Relay Module With Optocoupler (High Level Trigger)

The 3V 1 Channel Relay Module With Optocoupler is a compact relay control board designed for switching AC or DC loads using a 3V high level control signal. It incorporates an optocoupler to provide electrical isolation between the control circuit and relay switching section, helping protect sensitive microcontroller circuits from electrical interference.

The module is suitable for Arduino, Raspberry Pi, development boards, and other low voltage control systems. It can be used to control lighting, motors, solenoids, fans, and other electrical loads within the relay contact rating.
