Honeywell Thermal Solutions FSG L4079B1041 Pressure and Limit Controller

The Honeywell Thermal Solutions FSG L4079B1041 Pressure and Limit Controller is a differential pressure controller engineered for reliable safety and process protection. Featuring a diaphragm-operated actuator, it accurately senses pressure changes across air, gas, and fluid media with an operating range of 10 to 150 psi and a 30 psi differential. UL approved, this unit is built for dependable performance in demanding environments.

Designed for robust control, the unit uses a SPST 2-circuit configuration and supports contact ratings of 120 VAC 9.8 A full load (58.8 A locked rotor) and 240 VAC 4.9 A full load (29.4 A locked rotor). It offers a 1/4-inch female thread connection and can be mounted on a surface or with threaded fittings. The switch operates in a manual reset mode and breaks on pressure rise to prevent overpressure conditions.
