Kele Product UCP-722 Transducer

The Kele UCP-722 is a high-performance electro-pneumatic transducer designed to provide precise interface control between electronic building automation systems and pneumatic field devices. Engineered with advanced microcontroller-based poppet valve technology, this unit effectively converts 4-20 mA, 0-5 VDC, or 0-10 VDC input signals into a proportional 3-15 psig or 0-20 psig pneumatic output. As a veteran-grade analog-to-pneumatic signal converter, the UCP-722 is the direct technical replacement for the legacy EPC2GFSB. Unlike standard bleed-type transducers, its poppet valve design ensures zero steady-state air consumption, significantly reducing compressor load and improving system efficiency. The integrated LCD display allows for real-time local monitoring of branch pressure, while jumper-selectable configurations streamline field setup. Housed in a compact, snap-track compatible design, this HVAC pressure transducer maintains a linear output with less than 1% hysteresis, ensuring stable operation for dampers and valves in demanding commercial environments.

Key Benefits

• Low Power Consumption & Zero Bleed: High-efficiency poppet valves eliminate air waste during steady-state operation, preserving pneumatic system integrity.
• High Compatibility: Serving as the preferred EPC2GFSB replacement, it seamlessly integrates into existing 24 VAC/VDC power loops.
• Precise Monitoring: Field-readable LCD provides instantaneous diagnostic feedback for branch pressure without requiring external gauges.
• Flexible Input Selection: Multi-range jumper settings support 4-20mA to 3-15 psi conversion along with various voltage ranges (0-5V or 0-10V).
• Robust Reliability: Designed for consistent performance across a broad operating temperature range of 25° to 140°F (-4° to 60°C).

Common Questions

How do I configure the UCP-722 for a 3-15 psi range?
Use the onboard jumpers to select the 3-15 psig output range. Ensure your main air supply is regulated between 18 and 25 psig for optimal 3-15 psi branch response. The maximum supply pressure must not exceed 45 psig.

Does this unit retain branch pressure if power is lost?
Yes. Upon loss of power, the UCP-722 air valves remain closed, holding the branch pressure at its last value, which is critical for fail-last application requirements.

Can I mount this transducer on a standard DIN rail?
The UCP-722 comes with a snap-track housing that is compatible with standard mounting techniques used in control panels, though specific DIN rail adapters may be required depending on your enclosure setup.
