Johnson Controls P70LB-1C Pressure Control

Johnson Controls P70LB-1C Pressure Control is a dual-type control designed for refrigeration and HVAC systems. Operating from 20 inHg to 100 psi with a 65 psi differential, it delivers precise cut-in and cut-out, robust reliability, and easy field setup. The SPST contact configuration simplifies wiring for standard control circuits, while the 1/4 inch flare nut connections make installation straightforward.

It features a NEMA 1 enclosure suitable for non-corrosive refrigerants, and a 36 inch capillary length to accommodate tight installations. For compatibility across controls, this unit offers a wide voltage range, including AC ratings from 120 to 600 VAC (125 VA) and DC ratings from 120 to 300 VDC (57.5 VA).
