Fisher FIELDVUE DVC6200 Digital Valve Controller …

1 FIELDVUE DVC6200 Digital ValveControllerThe FIELDVUE DVC6200 Digital Valve Controller is aHARTr communicating instrument that converts atwo wire 4 20 mA control signal into a pneumatic outputto an actuator. It can easily be retrofitted in place ofexisting analog positioners on most Fisher and non Fisherpneumatic Linkage Less Non Contact Position Feedback Thehigh performance, linkage less feedback systemeliminates physical contact between the Valve stemand the DVC6200 . There are no wearing parts so cyclelife is Built to Survive The field proven DVC6200 instrumenthas fully encapsulated electronics that resist theeffects of vibration, temperature, and corrosiveatmospheres.

2 A weather tight wiring terminal boxisolates field wiring connections from other areas ofthe Accurate and Responsive The two stage positionerdesign provides quick response to large step changesand precise control for small setpoint of Usen Enhanced Safety The DVC6200 is a HART communicating device, so information can beaccessed anywhere along the loop. This flexibility canreduce exposure to hazardous environments andmake it easier to evaluate valves in hard to Faster Commissioning HART communications allowsyou to quickly commission loops with a variety oftools, either locally at the Valve assembly or LESSFEEDBACK SYSTEMW9616n Easy Maintenance The DVC6200 Digital valvecontroller is modular in design.

3 Critical workingcomponents can be replaced without removing fieldwiring or pneumatic Hardware Savings When installed in an integratedcontrol system, significant hardware and installationcost savings can be achieved. Valve accessories suchas limit switches and position transmitters can beeliminated because this information is available via theHART communication Increased Uptime The self diagnostic capability ofthe DVC6200 Digital Valve Controller provides valveperformance and health evaluation without shuttingdown the process or pulling the Valve assembly fromthe Improved Maintenance Decisions Digitalcommunication provides easy access to the conditionof the Valve .
