Johnson Controls P499RCP-107 Pressure Transducer

The Johnson Controls P499RCP-107 is a high-performance electronic pressure transducer engineered for demanding HVACR applications, specifically optimized for high-pressure refrigerants like R-410A. This P499 series transducer features a stainless steel construction that ensures chemical compatibility with various non-corrosive refrigerants and oils. It provides a linear 0.5 to 4.5 Vdc ratiometric output, allowing for precise monitoring within a 0 to 750 psi range. Designed for professional installation, this unit includes a 1/4" SAE 45 degree flare internal thread (7/16-20 UNF) with an integrated Schrader depressor, facilitating a secure connection to standard service ports without the need for additional adapters. The Packard electrical connection ensures a moisture-sealed interface, essential for preventing signal drift in high-humidity mechanical rooms. This transducer is a reliable choice for condenser fan speed control, head pressure management, and compressor protection cycles, delivering the accuracy required for modern building automation systems and standalone electronic controllers.

• Broad Pressure Spectrum: The 0 to 750 psi capability makes it ideal for high-pressure systems and trans-critical CO2 applications.
• Rugged Durability: Stainless steel sensing element protects against pressure spikes and environmental vibration.
• Ease of Integration: Standard Packard connector and ratiometric signal allow for seamless replacement in legacy and new installations.
• Leak Prevention: The internal flare thread with depressor minimizes refrigerant loss during installation and service.
• Precise Signal: Low total error band ensures accurate feedback for advanced PLC and HVAC controllers.

What is the primary application for the P499RCP-107?
This transducer is typically used for monitoring high-side discharge pressure in air conditioning and commercial refrigeration systems to manage fan cycling and head pressure.

Is this sensor compatible with R-410A systems?
Yes, the 750 psi rating is specifically designed to handle the operating pressures and surges associated with R-410A and other high-pressure refrigerants.

Does this unit require a specific wiring harness?
Yes, it utilizes a standard Packard style connector. If the existing harness is damaged, a compatible 3-wire Packard plug must be used to maintain the environmental seal.
