Gems Sensors & Controls DFC1D0R Level Control Board

The Warrick Controls DFC1D0 Level Control Board (MPN DFC1D0; alternate part number DFC1D0R) is a conductivity-based dual-function liquid level controller designed for industrial liquid level monitoring and relay activation in boiler systems and automated fluid-handling applications.

Its open-board assembly operates from 120 VAC with a 12 VAC secondary, features a 26K ohm sensitivity, and provides a Form C contact configuration (1 normally open and 1 normally closed) rated at 10 A resistive (1/3 HP) for 50/60 Hz, with spade-terminal connections.

UL 508 and UL 353 Listed, this controller is commonly used in boiler feeds, condensate tanks, cooling towers, and wastewater treatment or other industrial automation workflows requiring reliable low-water cutoff protection and differential level control; manufactured in the United States.
