  • Relay protection optocoupler voltage

    Relay protection optocoupler voltage

    It provides excellent electrical isolation (typically 2,500-5,000V) between input and output, making it perfect for protecting sensitive microcontrollers from high-voltage circuits, but it cannot directly drive solenoids, motors, contactors, or anything requiring more than 50mA. As an isolator, an optocoupler can prevent high voltages from affecting the side of the circuit receiving the signal. Transferring signals over a light.
