PXP2.3, PXP2.3FS, PXP2.3LG
GENERAL INFORMATION
The PXP2.3 is an electric to pneumatic transducer which
converts an analog electrical input signal to a
proportional pneumatic output. The PXP2.3 will
automatically modulate its control valve(s) to regulate
the branch line pressure to the selected set point as
determined by the input signal. The PXP2.3 o ers four
selectable input ranges which convert to a 0 to 15 psig
modulating output (See EPC product for 0 to 20 psig
outputs). A 0-5 VDC feedback signal indicating the
resultant branch line pressure is also provided. This
signal varies linearly with branch pressure (0 volts= 0
psig, 5 volts = 15 psig). The PXP2.3 incorporates two
valves and does not use air at set point. It's branch
exhaust ow and response time are not limited by an
internal restrictor and are similar to its load rate. If power
fails to the PXP2.3, branch line pressure remains
constant if the branch line does not leak air. The
PXP2.3FS is equipped with a N.O. branch exhaust valve
which allows exhaust of branch air on power failure. A
manual override (jumper selectable), which controls the
output pressure, is
troubleshooting.
MOUNTING INSTRUCTIONS
Circuit board may be mounted in any position. If
circuit board slides out of snap track, a
non-conductive "stop" may be required. Use only
ngers to remove board from snap track. Slide
out of snap track or push against side of snap
track and lift that side of the circuit board to
remove. Do not flex board or use tools.
WIRING INSTRUCTIONS
PRECAUTIONS
• Remove power before wiring. Never
connect or disconnect wiring with power
applied.
• When using a shielded cable, ground the
shield only at the controller end. Grounding
both ends can cause a ground loop.
• It is recommended you use an isolated
UL-listed class 2 transformer when powering
the unit with 24 VAC. Failure to wire the
devices with the correct polarity when
