Specifications
Available Configurations
J Integral mounting to the GX actuator
J Sliding‐stem applications
J Quarter‐turn rotary applications
The DVC2000 digital valve controller 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; split
ranging available.
Minimum Voltage: Voltage available at instrument
terminals must be 8.5 volts for analog control, 9.0
volts for HART communication.
Maximum Voltage: 30 volts DC
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 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 4 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.
