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 volts DC 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: 0.3 bar (5 psi) higher than
maximum actuator requirements, up to maximum
supply pressure
Maximum: 10 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. 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

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 1-3 below.
Emissions—Class A
ISM equipment rating: Group 1, Class A
Lightning and Surge Protection—The degree of
immunity to lightning is specified as Surge immunity
in table 1-3. For additional surge protection
commercially available transient protection devices
can be used.
