Fisherr FIELDVUEt 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
n 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.
n 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
n Accurate and Responsive— The two‐stage positioner
design provides quick response to large step changes and
precise control for small setpoint changes.
n 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
n 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.
LINKAGE‐LESS
FEEDBACK SYSTEM
n 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.
n Easy Maintenance— The DVC6200p digital valve
controller is modular in design. Critical working
components can be replaced without removing field
wiring or pneumatic tubing.
n 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.
Value
n Hardware and Installation Savings— Significant savings
can be achieved in reduced wiring, installation, and
hardware requirements compared to traditional
integrated control systems. By utilizing function blocks
such as Discrete Input and Analog Input blocks, the need
for limit switches and position transmitters can be
eliminated, providing additional savings in hardware and
installation costs.
n Improved Maintenance Decisions— Digital
communication provides easy access to the condition
of the valve. Sound process and asset management
decisions can be made by analysis of valve information
through device alerts that provide details of the
operational state of the final control element (see
figure 1).
