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
(3)
Air Quality: Supply pressure must be clean, dry air
that meets the requirements of 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
Natural Gas: Natural gas must be clean, dry,
oil-free, and noncorrosive. H
2
S content should not
exceed 20 ppm.
