Microprocessor-controlled valve control

GEMÜ 4242

ConfigureTechnical data sheet
Compact position feedback device with translucent cover, actuating rod, and side connections for precise valve monitoring in industrial applications.

Universal valve activation with wide-angle LEDs

Product information

The GEMÜ 4242 combi switchbox is suitable for installation on pneumatically operated linear actuators. The position of the valve spindle is reliably electronically detected and evaluated using play-free and non-positive mounting. Integrated pilot valves enable direct activation of the process valve connected to them. Intelligent microprocessor-controlled functions facilitate commissioning and support during operation. The current position of the valve is displayed via high-visibility LEDs and fed back via electrical signals.

Key features

  • Fieldbus connection AS-Interface (3.0), ASi-5 and DeviceNet (optional)
  • Communication and programming interface IO-Link
  • Adjustable switch point tolerances
  • Speed-AP function for fast mounting and initialization
  • High visibility position indicator by LED
  • On-site or remote end position programming via programming input
  • Integrated manual override
