  • GEMU 4221 Combi switchbox with integrated 3/2 way pilot valve

    Construction
    The GEMU 4221 combi switchbox with integrated 3/2 way pilot valve for pneumatically operated quarter turn actuators has a micro-processor controlled intelligent position sensor as well as an analogue integrated travel sensor system. The optical position feedback is via LEDs. Electrical activation and position feedback is provided via 24 V DC signals or via fieldbus (AS-Interface, DeviceNet, LON).
    The GEMU 4221 combi switchbox has a solid transparent plastic housing cover and a metal base

    Features

    • Integrated end position control
    • Integrated pilot valve for single or double acting actuators
    • Integrated travel and system control
    Advantages
    • Design:
      • 24 V version but also direct field bus connection to
