The JC-22-HDPCO-8 is a draft range differential pressure switch with red warning light and time delayed cutout relay contacts. The normally energized cutout relay contacts open when the differential pressure is higher than the setpoint for more than 8 seconds. The setpoint is field adjustable over the 0.05” to 9.0”wc range. The JC-22-HDPCO-8 is a direct replacement for the Hays Cleveland model # AFS-952-55-B.
JC-22-LDCO-8 version is available for low positive pressure or low negative pressure applications.
