Description

DVC6020 Digital Valve Controller | Fisher Fieldvue

• Product: Digital Valve Controller
• Product No. : DVC 6020
• Manufacturer : Fisher Fieldvue
• Origin : USA

Description
DVC6020 Digital Valve Controller | Fisher Fieldvue are communicating, microprocessor‐based current‐to‐pneumatic
instruments. In addition to the traditional function of converting an input current signal to a pneumatic output pressure, the DVC6000 digital valve controller communicate via HART protocol.
DVC6000 digital valve controllers are designed to directly replace standard pneumatic and electro‐pneumatic valve mounted positioners.

Specification:

Input Signal
Point‐to‐Point:
Analog Input Signal: 4‐20 mA DC, nominal
Minimum Voltage Available at instrument terminals must be 10.5 volts DC for analog control, 11 volts DC
for HART communication
Minimum Control Current: 4.0 mA
Minimum Current w/o Microprocessor Restart: 3.5 mA
Maximum Voltage: 30 volts DC
Overcurrent Protection: Input circuitry limits current to prevent internal damage.
Reverse Polarity Protection: No damage occurs from reversal of loop current.

Multi‐drop:
Instrument Power: 11‐30 VDC at approximately 8 mA
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: 0.4 bar (6 psig)
Maximum Span: 9.5 bar (140 psig)
Action: Double, Single direct, and Single reverse

Additional info

Supply Pressure
Recommended: 0.3 bar (5 psig) higher than maximum actuator requirements, up to maximum supply pressure

Maximum: 10.0 bar (145 psig) or maximum pressure rating of the actuator, whichever is lower Medium: Air or Natural Gas
Air: Supply pressure must be clean, dry air that meets the requirements of ISA Standard 7.0.01.
Natural Gas: Natural gas must be clean, dry, oil‐free,and noncorrosive. H2S content should not exceed 20
ppm.
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…more
