Johnson Controls P29NA-3 Pressure Control W/Time Delay 20" Hg 100 PSI 24V

The Johnson Controls P29NA-3 PSI Control with Time delay is a multifunctional pressure switch designed for HVAC and industrial applications. This switch can handle pressure ranges of 20 to 2000 PSI and is reliable at operating temperatures of -40°C to 85°C. It can be used to accurately control high-pressure conditions since it has an electrical rating of 5A. This switch is used mostly in HVAC systems, detects change in pressure and acts depending on the pre-set values to turn on or off equipment. The time-delay function ensures that the functioning is controlled and prevents cycling at high speeds that would otherwise compromise the efficiency of the system and cause damage.
