Fisher™ FIELDVUE™ DVC6200p Digital Valve Controller
The FIELDVUE DVC6200p digital valve controller is a
PROFIBUS PA communicating instrument that
converts a digital control signal into a pneumatic
output to an actuator. It can easily be retrofitted in
place of existing analog positioners on most Fisher and
non‐Fisher pneumatic actuators.
Features
Reliability
• Linkage‐Less Non‐Contact Position Feedback— The
high performance, linkage‐less feedback system
eliminates physical contact between the valve stem
and the DVC6200p. There are no wearing parts so
cycle life is maximized.
• Built to Survive—The field proven DVC6200p
instrument has fully encapsulated electronics that
resist the effects of vibration, temperature, and
corrosive atmospheres. A weather‐tight wiring
terminal box isolates field wiring connections from
other areas of the instrument.
Performance
• Accurate and Responsive— The two‐stage positioner
design provides quick response to large step
changes and precise control for small setpoint
changes.
• Travel Control/Pressure Fallback— Valve position
feedback is critical to the operation of the digital
valve controller. The DVC6200p can detect position
feedback problems and automatically revert to I/P
transducer mode to keep the valve operational.
Ease of Use
• Enhanced Safety— The DVC6200p is a PROFIBUS PA
communicating device, so information can be
accessed anywhere along the loop. This flexibility
can reduce exposure to hazardous environments
and make it easier to evaluate valves in hard to
reach locations.
• Fast Commissioning— PROFIBUS communication
allows you to quickly commission loops remotely
using the PROFIBUS configuration tool with the
DVC6200p Electronic Device Description (EDD).
The DVC6200p can also be locally
calibrated/commissioned by shorting the auxiliary
terminal located in the terminal box.
• Easy Maintenance— The DVC6200p digital valve
controller is modular in design. Critical working
components can be replaced without removing
field wiring or pneumatic tubing.
• Stroke Valve— The Stroke Valve Test is used to
confirm proper valve operation. It helps to validate
the auto‐calibration after guided setup is complete.
