UNIVERSAL ELECTRONIC / PNEUMATIC TRANSDUCERS
UCP-722 SERIES
JUMPER CONFIGURATION
INPUT Select CURRENT (4-20 mA) or
VOLTAGE (0-5V or 0-10V)
VOLTAGE For voltage mode of operation,
select 0-5V or 0-10V
SCALING Select 0-20 psi or 3-15 psi scaling
MODE Select AUTO for normal operation,
or MANUAL to adjust pressure
using pushbuttons
POWER/SIGNAL OPTIONS
ALARM MODE RELAY The alarm contacts will open if
the unit cannot obtain 80% of
commanded pressure within two (2)
minutes
GND/COMMON Power supply ground and signal
common
INPUT SIGNAL 4-20 mA, 0-10 VDC, or 0-5 VDC
input from control system
POWER 22-30 VDC, 20-30 VAC. From
control system or external power
supply or transformer
NOTE: In 24 VAC transformer applications, one side of
transformer secondary is connected to signal.
QUICK INSTALL
CAUTION: Use electrostatic discharge precautions (e.g., use
of wrist strips) during installation and wiring to
prevent equipment damage.
1. Mount transducer using screws provided. Take care to avoid
damaging electronic components.
2. Wire transducer as shown in wiring diagram.
3. Configure jumpers for desired operation as shown.
4. Attach pressure tubing to hose barbs. Observe MAIN and
BRANCH port labels. Use flexible 1/4" O.D. poly tubing for
main and branch pneumatic connections.
CAUTION: Main supply pressure must not exceed 45 psig.
PL OPTION
PRESSURE LOSS ALARM OPTION
Normally closed, solid-state contacts open if main
supply pressure fails, or transducer is otherwise unable
to produce correct branch pressure. Connect to digital
input of control system for alarm status indication. If
commanded pressure is not within 80% inside a two (2)
minute window, alarm contacts will open.
• 0-20 psi alarm contact will not change state when
commanded pressure is four (4) psi or less
• 3-15 psi alarm contact will not change state when
commanded pressure is 5.4 psi or less
