DESCRIPTION
The UCP-242 Current/Pneumatic Transducer provides
low cost pneumatic control of valves, dampers, or other
pneumatic devices. The UCP-242 comes with snap-track
for easy mounting. Quick-disconnect terminals provide easy
wiring removal for servicing. Barbed fittings for 1/4" plastic
tubing and an in-line filter are provided.
FEATURES
• Inline filter provided
• Snap-track mounting
• 1/4" (0.64 cm) barbed tube connectors
• Quick-disconnect terminals
• Loop-powered control
• Excellent linearity
• Low hysteresis
• No calibration required

OPERATION
The UCP-242 accepts a 4-20 mA signal and outputs 3-15
psig. The unit is loop-powered, requiring no power supply
for controlling pneumatic devices. Upon a loss of signal, the
UCP-242 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 a slower response time.
