Fisherr FIELDVUEt DVC2000 Digital Valve
Controller

The FIELDVUE DVC2000 digital valve controller is
simple to use, compact, and designed for easy
mounting. It converts a 4-20 mA input signal into a
pneumatic output signal, which feeds the control valve
actuator. Instrument setup is performed with a push
button and liquid crystal display (LCD) interface. This
interface is protected from the environment within a
sealed enclosure. The interface supports multiple
languages, available in two language pack options.

The DVC2000 uses a two-stage positioner design. The
pre-amplifier stage provides high static gain for
responsiveness to small changes in the input signal.
The power amplifier stage delivers the right volume of
air to the actuator, combining superior dynamic

performance with minimal steady-state air
consumption.

The high performance, linkage-less feedback system
eliminates physical contact between the valve stem
and the positioner. There is no wear of parts so cycle
life is maximized. Additionally, the elimination of
levers and linkages reduces the number of mounting
parts and the mounting complexity. Positioner
replacement and maintenance is simplified because
the feedback parts stay connected to the actuator
stem.

Designed to meet intrinsically safe and non-incendive
requirements, this instrument delivers scalable
functionality and high performance in a small package.

reversal of loop current

Output Signal

Pneumatic signal as required by the actuator, up to
full supply pressure

Minimum Span: 0.5 bar (7 psig)
Maximum Span: 7 bar (101 psig)
Action: Single Acting, direct

Supply Pressure

(1)

Recommended: 0.5 bar (7 psig) greater than the
maximum actuator requirements
Maximum: 7 bar (101 psig)

Supply pressure must be clean, dry air or
noncorrosive, nonflammable gas that meets the
requirements of ISA Standard 7.0.01. A maximum 40
micrometer particle size in the air system is
acceptable. Further filtration down to 5 micrometer
particle size is recommended. Lubricant content is
not to exceed 1 ppm weight (w/w) or volume (v/v)
basis. Condensation in the air supply should be
minimized.

Temperature Limits

-40 to 85_C (-40 to 185_F). LCD may not be readable
below -20_C (-4_F).

Independent Linearity

Emissions—Class A
ISM equipment rating: Group 1, Class A

Tested to NAMUR NE21 requirements

Vibration Testing Method

Tested per ANSI/ISA-75.13.01 Section 5.3.5. A
resonant frequency search is performed on all three
axes. The instrument is subjected to the ISA specified
1/2 hour endurance test at each major resonance,
plus an additional two million cycles.

Input Impedance

The input impedance of the DVC2000 active
electronic circuit is not purely resistive. For
comparison to resistive load specifications, an
equivalent impedance of 450 ohms may be used. This
value corresponds to 9 V @ 20 mA.

Features

n Simplicity—The DVC2000 is easy to use. If you are

mounting the instrument for the first time, the
linkage-less feedback system is easy to install. Once
a magnet array is assembled to the valve stem,
positioner replacement is simple since there are no
physically connected parts.

At its very basic functionality, the DVC2000 digital
valve controller has a local user interface that will
allow you to configure, calibrate, and tune the
instrument. If the I/O Options Package is installed,

you can calibrate the 4-20 mA transmitter and
configure the limit switch action. Running the Quick
Setup routine calibrates and tunes the instrument
specifically for that actuator.

The full text display in the local interface is easy to
navigate, in part due to the selection of languages.
Each unit can be configured to display English,
German, French, Italian, Spanish, Japanese or
Chinese. The standard language pack also includes
Portuguese, Russian, Polish, and Czech. An optional
language pack replaces these four languages with
Arabic.
