Johnson Controls P70DA-400 Single Pole Pressure Control Overview
The Johnson Controls P70DA-400 is a high-side single pole pressure control engineered for reliable refrigeration and HVAC system protection. With a sensing range of 200 PSI to 610 PSI and an Open High (Open Hi) action, this control opens the circuit when pressure rises above the set point, providing critical high-pressure safety cutout functionality. The manual reset design ensures that a technician must physically reset the control after a trip event, preventing automatic restart until the root cause of the pressure fault has been addressed.
Key Features
- Pressure sensing range: 200 PSI to 610 PSI
- Switch action: Open Hi — opens on pressure rise (high-pressure cutout)
- Switch type: SPST (Single Pole, Single Throw)
- Reset type: Manual reset — requires manual intervention after trip
- Capillary length: 36 inches for flexible installation positioning
- Single pole design for straightforward circuit integration
- Durable construction suited for demanding commercial and industrial refrigeration environments
Application & Benefits
The P70DA-400 is ideal for use as a high-pressure safety control on refrigeration compressors, condensing units, and commercial HVAC equipment. The manual reset feature is a critical safety requirement in many commercial refrigeration applications, ensuring that nuisance restarts do not occur and that equipment is inspected before being returned to service. The 36″ capillary provides installation flexibility, allowing the sensing element to be positioned at the optimal location on the refrigerant circuit.
