8696 Digital Electropneumatic Positioner

Compact positioner for integrated mounting on pneumatically controlled process control valves. The set-point value setting default occurs via standard signal 4-20 mA. A sensor element with contactless function records the valve spindle position. Simple start-up via automatic TUNE function and setting with the aid of DIP switch: sealing threshold, characteristic selection, inversion of direction, manual/automatic operating state switchover, digital input. A software interface can be used for the linearisation of the operating characteristic with the aid of a freely programmable characteristic, amongst other things. The status indicator functions using LEDs. An analogue position feedback can be optionally integrated.


  • Compact stainless steel design
  • Start-up with automatic TUNE function
  • Contact-free position sensor
  • Integrated pilot air duct in the actuator
  • Digital communication IO-Link, Bürkert system bus (büS)
