The Johnson Controls P233A-4-AA is part of the P233 Series Electronic Pressure Transducers. These devices are designed for HVAC and refrigeration applications, converting refrigerant pressure into a precise electrical output signal (typically 0–5 VDC) for monitoring and control. The “-4-AA” variant indicates a specific pressure range calibration and voltage output type.

• Type: Electronic Pressure Transducer
• Series: P233A (PENN Controls, Johnson Controls)
• Function: Provides continuous electrical feedback proportional to refrigerant pressure.
• Application: Used in chillers, rooftop units, refrigeration systems, and building automation.
• Output Signal: Voltage (0–5 VDC) proportional to sensed pressure.
