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.
