Information About P70LB-1C
The P70LB-1C is an all-range model in the Johnson Controls/PENN P70 Series. Its steel case encloses pressure-actuated bellows and a mechanically operated switching mechanism. The control connects to compatible non-corrosive refrigerant circuits through capillary tubing with flare fittings. Visible pressure scales and an external low-pressure adjustment knob support setting and checking the operating thresholds.
Key Features:
- Dual pressure sensing: Combines high-side and low-side pressure control in one device.
- Low-pressure adjustment: Covers a range from 20 inches of mercury vacuum to 100 psig.
- High-pressure adjustment: Provides a setting range of 100–500 psig.
- Automatic reset: Resets after pressure returns to the applicable operating threshold.
- Single switching circuit: Uses single-pole, single-throw contacts for the connected control circuit.
- Remote pressure connections: Includes 36-inch capillaries with 1/4-inch flare nuts.
- External setting visibility: Provides calibrated pressure scales for checking adjustments.
- Protective enclosure: Uses a NEMA 1 steel case for indoor installation.
The P70LB-1C delivers the reliability and precision required for combined high- and low-pressure compressor control in compatible refrigeration systems.
