Input Signal (Process Sensor Range
(1)
)
Lower and Upper Range Limits: See tables 1-3
and 1-4
Maximum Allowable Operating Limits: See
tables 1-3 and 1-4
Output Signal
(1)
Proportional-Only, Proportional-Plus-Reset,
or Proportional-Plus-Reset-Plus-Rate Range:
0.2 to 1.0 bar or 0.4 to 2.0 bar (3 to 15 psig or 6
to 30 psig)
Differential Gap Range: 0 and 1.4 bar (0 and 20
psig) or 0 and 2.4 bar (0 and 35 psig)
Action: Field-reversible between direct
(increasing sensed process pressure increases
output pressure) or reverse (increasing sensed
process pressure decreases output pressure).
Process Scale
Standard scale is matched to the range of the
sensing element, with the exception of receiver
controllers. Optional
(2)
scales are available.
Process Connections
Standard: 1/4 NPT, internal, stainless steel (all
input ranges)
Optional: 1/2 NPT, see table 1-5
Supply and Output Connections
1/4 NPT, internal
