ELECTRONIC / PNEUMATIC TRANSDUCER
UCP-422 SERIES
DESCRIPTION
The UCP-422 Series electronic/pneumatic transducer
provides low-cost pneumatic control of valves, dampers, or
other pneumatic devices. The UCP-422 consists of a totally-
enclosed transducer with provisions for optional DIN rail or
surface mounting in either of two planes. Externally-mounted
pneumatic filters are not required. Quick-disconnect terminals
provide easy wiring removal for servicing. When DIN rail
mounting is used, this compact device requires only a 4"H x
2"W (10.2 x 5.1 cm) mounting area, providing efficient use of
panel space.
FEATURES
• Slim-line mounting to save panel space
• Universal mounting tabs
• Totally enclosed
• 1/4" (0.64 cm) barbed tube connectors
• Quick-disconnect terminals
• Loop-powered control (base model)
• No external filter required
• Excellent linearity
• Low hysteresis
• No calibration required
OPERATION
The UCP-422 Series accepts a 4-20 mA signal and outputs
3-15 psig (20.7-103.4 kPa). Used in its base configuration, it
requires no power supply for controlling pneumatic devices.
Upon a loss of signal or power, the UCP-422 will eventually
bleed the pressure in the branch line. This transducer is well
suited for the control of small to medium volume loads, such
as small to medium pneumatic actuators. Large volume loads,
such as large pneumatic actuators or long tubing runs may
also be controlled but will exhibit slower response time.
