Output Signal
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
Process Connections
Standard: 1/4 NPT, internal, stainless steel (all
input ranges)
Optional: 1/2 NPT, see table 1-5
