option
Remote-Mounted Instrument
(1)
DVC6005 SIS: Base unit for 2 inch pipestand or
wall mounting
DVC6015: Feedback unit for sliding-stem
applications
DVC6025: Feedback unit for rotary or long-stroke
sliding-stem applications
DVC6035: Feedback unit for quarter-turn rotary
applications
DVC6000 SIS digital valve controllers can be
mounted on Fisher and other manufacturers rotary
and sliding-stem actuators
Input Signal
Point-to-Point:
Analog Input Signal: 4-20 mA DC, nominal
Minimum voltage available at instrument terminals
must be 10.5 VDC for analog control, 11 VDC for
HART communication
Minimum Control Current: 4.0 mA
Minimum Current w/o Microprocessor Restart:
3.5 mA
Maximum Voltage: 30 VDC
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
Supply Pressure
(2)
Recommended: 1.7 bar (25 psi) or 0.3 bar (5 psi)
plus the maximum actuator requirements,
whichever is higher
Maximum: 10 bar (145 psig) or maximum pressure
rating of the actuator, whichever is lower
Supply Medium
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. H

S 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

The low bleed relay is the standard relay for
DVC6000 SIS digital valve controllers, used for
On/Off applications. Performance may be affected
in throttling applications.
