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, 30 mA 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
(1)
Supply Pressure
Recommended: 0.5 bar (7 psig) greater than the
maximum actuator requirements
Maximum: 7 bar (101 psig)
Supply pressure medium must be clean, dry air or
noncorrosive gas
Per 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
Per ISO 8573-1
Maximum particle density size: Class 7
Oil content: Class 3
Pressure Dew Point: Class 3 or at least 10_C less than
the lowest ambient temperature expected
Temperature Limits
-40 to 80_C (-40 to 176_F). LCD may not be readable
below -20_C (-4 _F).
Altitude Rating
Up to 2000 meters (6562 feet)
Humidity
5-95% relative humidity (-40 to 80_C [-40 to 176_F])
Air Consumption
Supply pressure
At 1.5 bar (22 psig)
At 4 bar (58 psig)

Air Capacity
Supply pressure
At 1.5 bar (22 psig)
At 4 bar (58 psig)

Electromagnetic Compatibility
Meets EN 61326‐1:2013
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.
