    FEATURES

    • Robust galvanic isolation (UL508 and EN 61131-2 certified) to protect the 3.3V/5V control domain of an industrial control system from the harsh 24V (typ.) process side
    • 8-channel high side power-switching capabilities of up to 1.2A per channel
    • Active current limitation and over-temperature protection
    • Common diagnostic feedback for over-temperature and for VBB under-voltage

    APPLICATIONS

    • PLCs
    • Distributed control systems
    • General control equipment
    • Robotics
    • Solid state relay
