Kele Product UCP-822A-PL Transducer

The Kele UCP-822A-PL is a professional-grade electronic-to-pneumatic transducer designed for precise pressure control in commercial HVACR and building automation systems. As a direct replacement for EPT-102-1, this unit utilizes advanced poppet valve technology and microcontroller-based digital control to achieve high accuracy without ongoing air consumption in a steady state. This E-P transducer PWM model is field-configurable, supporting selectable analog inputs such as 4-20mA, 0-10 VDC, and pulse width modulation, making it a versatile pneumatic transducer for various controller types. The integrated LCD display allows for real-time local indication of branch pressure, while the onboard pressure loss alarm provides a critical contact closure if setpoints are not reached. Featuring a standard 0-25 psig output range and 24V power supply compatibility, this DDC to pneumatic transducer ensures reliable performance for modulating dampers and valves in complex mechanical sequences.

Key Benefits for HVACR Contractors:

• Zero Air Consumption: High-performance poppet valves eliminate constant bleed, reducing compressor load and energy costs.
• Universal Input Compatibility: Seamlessly integrates with various signals including PWM, Tri-state, and 4-20mA via field-selectable jumpers.
• High Accuracy: Delivers precise control with less than 1% full scale linearity, hysteresis, and repeatability for tight system loops.
• Fail-Safe Operation: Retains last branch pressure value upon power loss, providing stability during electrical interruptions.
• Direct Retrofit: Simplifies service calls as the authorized replacement for EPT-102-1 with easy snap-track mounting.

Common Questions Regarding the UCP-822A-PL:

How do I configure the input signal on this model?
Technicians can select the input type (Voltage, Current, or PWM) using the onboard configuration jumpers. For PWM or Tri-state modes, ensure the proper pull-up settings are verified to match your controller’s output signal character.

Is this transducer compatible with high-pressure main lines?
This unit is designed for standard pneumatic control systems. The maximum supply pressure is 45 psig, and the programmable branch output range is up to 25 psig. Always use clean, dry air or inert gas to prevent poppet valve contamination.

Can I use this for variable volume applications?
Yes, its fast response time and configurable zero and span settings make it ideal for modulating VAV boxes and large-scale pneumatic actuator positioning in varying HVAC loads.
