Construction

The GEMU 4222 combi switchbox with integrated 3/2 way pilot valve for pneumatically operated linear actuators has a microprocessor 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 field bus (AS-Interface, DeviceNet, LON). The GEMU 4222 combi switchbox has a solid transparent plastic housing cover and a metal base.
