20 In HG Vacuum to 100-PSI Differential Max Bellows 325 Low Pressure Cutout Control (Johnson Controls)


P29NC is a low-pressure control with time delay and lockout, which requires manual reset. A drop in pressure energizes the time delay relay and opens a contact after 60 seconds, shutting down the equipment. The
time delay prevents nuisance shutdowns due to momentary fluctuations in system pressures.
