KELE UNIVERSAL ELECTRONIC / PNEUMATIC TRANSDUCERS
UCP-822A SERIES
DESCRIPTION
The Kele UCP-822A microcontroller based electronic/
pneumatic transducer incorporates high performance
poppet valve technology and low-power coils with digital
control to provide unmatched accuracy and proven reliability.
In addition to providing reliable, stable operation, the poppet
valves used in the UCP-822A consume no air. The UCP-
822A features programmable pressure ranges and an LCD
display. This universal transducer has field selectable analog
inputs for 4-20mA, voltage, tri-state, or PWM.
FEATURES
• Extended PWM and Tristate settings
• Programmable pressure output up to 25 psig
• Field-selectable signal inputs (4-20mA, voltage, tri-
state, PWM)
• LCD display for local indication of readings
• No air consumption and quiet operation
• Easy mounting with snap track housing
• Pressure loss or manual mode alarm
• Optional analog output 4-20mA or 0-10 VDC selectable
OPERATION
The UCP-822A-PL converts a selectable analog, tri-state or
PWM input to a programmable psig output (0-25 psig range).
The transducer is powered with 24 VAC/VDC. Upon a loss in
power, the UCP-822A-PL air valves remain closed, so branch
pressure will remain at the last value. The pressure loss alarm
provides a contact closure if the UCP-822A-PL is unable to
achieve the desired output within a fixed length of time. This
alarm may be changed to alarm if the transducer is set for
manual operation. The UCP-822A-AO-PL adds an analog
output for feedback of the branch pressure.
