Specifications
Available Mountings
J Integral mounting to the Fisher GX Control Valve
and Actuator System
J Sliding-stem applications
J Quarter-turn rotary applications
DVC2000 digital valve controllers can also be
mounted on other actuators that comply with
IEC 60534-6-1, IEC 60534-6-2, VDI/VDE 3845 and
NAMUR mounting standards.
Input Signal
Analog Input Signal: 4-20 mA DC, nominal; can be
configured for split range
Minimum Voltage: Voltage available at instrument
terminals must be 8.5 volts for analog control, 9.0
volts for HARTr communication
Maximum Voltage: 30 VDC
Minimum Control Current: 4.0 mA (below 3.5 mA
may cause microprocessor restart)
Overcurrent Protection: Input circuitry limits current
to prevent internal damage
Reverse Polarity Protection: No damage occurs from
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).

Electromagnetic Compatibility
Meets EN 61326-1 (First Edition)
Immunity—Industrial locations per Table 2 of
the EN 61326-1 standard. Performance is
shown in table 1 below
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.
