Digital electropneumatic positioner for the integrated mounting on process control valves
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 parametrizing using device DTM. A software interface can be used for the linearization 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.
