Fisherr FIELDVUEt DVC6200 SIS Digital
Valve Controller for Safety Instrumented
Systems (SIS)
The FIELDVUE DVC6200 SIS digital valve controller is a
HARTr communicating instrument for use in valve
applications such as Emergency Shutdown, Emergency
Blow Down, Emergency Venting, and Emergency
Isolation. The DVC6200 SIS is capable of monitoring
the health of and controlling the safety shutdown
function of a valve and can easily be installed on most
Fisher and non‐Fisher pneumatic actuators.
Features
Reliability
n Linkage‐less Position Feedback—The high
performance, linkage‐less feedback system
eliminates physical contact between the valve stem
and the DVC6200 SIS. This minimizes the affects of
pipeline vibration and environmental corrosion.
n Built to Survive—The field proven DVC6200 SIS
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.
Safety
n Partial Stroke Testing (PST)—This is a small ramp
test that moves the valve, without disrupting the
process, to detect a stuck valve. Testing can be
automated, or manually initiated with an external
pushbutton or Fisher LCP100 Local Control Panel.
n Full Stroke Testing (FST)—This is a full ramp over the
entire valve travel range that is typically performed
during a shut down. This test can reveal failures
undetected by the PST on-line diagnostic testing.

Ease of Use
n Remote Access—The DVC6200 SIS 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 communication
allows you to quickly commission loops with a
variety of tools, either locally at the valve assembly
or remotely.
n Easy Maintenance—The DVC6200 SIS digital valve
controller is modular in design. Critical working
components can be replaced without removing
field wiring or pneumatic tubing.
Value
n Spurious Trip Protection—PST Pressure Limit defines
the output pressure threshold that will abort the
partial stroke test if exceeded. This prevents the
actuator from completely exhausting pressure and
potentially causing a spurious trip in a sticking valve
scenario.
