Description:

This relay is used to sense suction and/or discharge pressures across a coil or fan and control pneumatic damper actuators or valves piped downstream from this device. By the use of sensing lines located at a fan suction and discharge and piped to the "hi" and "lo ports of this relay, this device is able to detect whether or not a fan is operating. This same operation can also be detected by using one port of the 2374 as a reference port and piping the other port to the fan suction or discharge providing there is a differential pressure of at least 0.15" W.C. This is not a "snap acting" device and must be used only on applications where there is a positive change, 0 to 0.15" W.C., in the sensed differential pressure. Several applications of this relay would be the sensing of fan operation in unit ventilators, fan coil units and air handling units. Ruggedly constructed of Lexan and using a molded neoprene diaphragm, this relay is designed to give many years of trouble-free service.
