DVC2000 Digital Valve Controller | Fisher 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 an
enclosed push button and liquid crystal display (LCD) interface. The interface supports multiple languages, available in two language pack options.

Specification of DVC2000 Digital Valve Controller :
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 HART communication
Maximum Voltage: 30 VDC
Minimum Control Current: 4.0 mA (below 3.5 mA
may cause microprocessor restart)
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 medium must be clean, dry air or
noncorrosive gas that meets the requirements
of ISA Standard 7.0.01 or ISO 8573-1
Temperature Limits(1)
-40 to 80C (-40 to 176F). LCD may not be readable
below -20C (-4F).
Principle of Operation:
The input signal provides electrical power and the set point simultaneously. The 4-20 mA signal is routed into the terminals through a twisted pair of wires. The unit’s mainboard contains a microprocessor that continuously runs a digital control algorithm.
This algorithm produces a “drive signal” to the I/P converter. The I/P converter assembly (or pre-amplifier) is connected to supply pressure and converts the electronic “drive signal” into a pneumatic “pressure signal.” This pressure signal is the input to the pneumatic relay assembly….more
