Digital Valve Controller
Fisher® FIELDVUE™ DVC6200 digital valve controllers are HART® communicating, microprocessor-based current-to-pneumatic instruments with linkage-less, non-contact travel feedback. Three important functions are performed by the DVC6200 instrument:Traditional positioning of a control valve by converting the 4-20mA DC input signal from the process controller to a pneumatic output signal to the actuator.Automatic calibration and configuration utilizing the power of microprocessor technology.Communication capability via the HART communications protocol to provide instrument and valve diagnostic information.This instrument provides one platform for any pneumatic actuator application. The DVC6200 can be installed on sliding-stem, rotary, single- or double-acting actuators.Designed for ruggedness and easy maintenance, the DVC6200 is modular. The single master module can be removed from the instrument housing without disconnecting the field wiring, pneumatic connections, or stem linkages. This master module contains the critical sub-modules so component removal is quick and simple.
