DVC2000 Digital Valve Controller August 2017 Fisher ...

1 fieldvue DVC2000 Digital ValveControllerThe fieldvue DVC2000 Digital Valve Controller issimple to use, compact, and designed for easymounting. It converts a 4-20 mA input signal into apneumatic output signal, which feeds the control valveactuator. Instrument setup is performed with anenclosed push button and liquid crystal display (LCD)interface. The interface supports multiple languages,available in two language pack DVC2000 uses a two-stage positioner design. Thepre-amplifier stage provides high static gain forresponsiveness to small changes in the input power amplifier stage delivers the right volume ofair to the actuator, combining superior dynamicperformance with minimal steady-state high performance, linkage-less feedback systemeliminates physical contact between the Valve stemand the positioner.

2 There is no wear of parts so cyclelife is maximized. Additionally, the elimination oflevers and linkages reduces the number of mountingparts and the mounting complexity. Positionerreplacement and maintenance is simplified becausethe feedback parts stay connected to the to meet intrinsically safe and non-incendiverequirements, this instrument delivers scalablefunctionality and high performance in a small Digital Valve ControllerD103167X012 Product : DVC2000 August 2017 DVC2000 Digital Valve ControllerD103167X012 Product : DVC2000 August 2017 2 SpecificationsAvailable MountingsJIntegral mounting to Fisher 657/667 or GXactuatorsJSliding-stem applicationsJQuarter-turn rotary applicationsDVC2000 Digital Valve controllers can also bemounted on other actuators that comply with IEC 60534-6-1, IEC 60534-6-2, VDI/VDE 3845 andNAMUR mounting SignalAnalog Input Signal: 4-20 mA DC, nominal.
