Fisherr FIELDVUEt DVC6200 Digital Valve
Controller
The FIELDVUE DVC6200 digital valve controller is a
HARTr communicating instrument that converts a
two‐wire 4‐20 mA 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 DVC6200. There are no wearing parts so cycle
life is maximized.
n Built to Survive—The field proven DVC6200 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 a digital valve
controller. The DVC6200 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 DVC6200 is a HART
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.

n Faster Commissioning— HART communications allows
you to quickly commission loops with a variety of
tools, either locally at the valve assembly or remotely.
n Easy Maintenance— The DVC6200 digital valve
controller is modular in design. Critical working
components can be replaced without removing field
wiring or pneumatic tubing.
Value
n Hardware Savings— When installed in an integrated
control system, significant hardware and installation
cost savings can be achieved. Valve accessories such
as limit switches and position transmitters can be
eliminated because this information is available via the
HART communication protocol.
n Increased Uptime— The self‐diagnostic capability of
the DVC6200 digital valve controller provides valve
performance and health evaluation without shutting
down the process or pulling the valve assembly from
the line.
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 Fisher ValveLinkt software.
