Compact positioner for integrated mounting on pneumatically controlled process

control valves. The set-point value setting default occurs via standard signal

4 - 20 mA and/or via AS interface. 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

Additional options available for parametrising using device DTM. 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.
