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.
