Warrick DFC1B0K000306 Control

The Warrick DFC1B0K000306 is a mission-heavy dual function liquid level control engineered for simultaneous management of two independent probe circuits. Operating on a 120V AC primary supply, this open-board controller is factory-configured with a specific 26K Ohm sensitivity, making it the industry standard for sensing conductive liquids such as tap water or condensate in industrial HVACR environments. The dual-logic architecture allows a single board to handle both high/low differential service (pump-up or pump-down) and a dedicated single-level function, typically utilized for low-water cutoff (LLCO) protection in boiler or steam generator applications.

Designed for seamless integration into existing control panels, the DFC1B0K000306 features rugged 1/4-inch male quick-connect terminals for line power and 3/16-inch terminals for probe connections. The Series DF circuitry utilizes a secondary 12V AC signal on the probes to prevent electrolysis and probe plating, ensuring long-term signal integrity. This specific model (C1B) incorporates 1/8-inch panel standoffs and a standard 3-second time delay on decreasing levels to filter out nuisance trips caused by turbulence or surging. For contractors, this conductive liquid level relay provides a simplified, solid-state solution that meets CSD1 requirements when configured with the appropriate manual reset options.

• Dual-Function Logic: Simultaneously handles one differential level function and one independent single-level function on a single compact board.
• Optimized Sensitivity: Pre-set at 26,000 Ohms to minimize false triggers from vapor or moisture while maintaining precise conductivity detection.
• Reduced Electrolysis: Low secondary voltage (12V AC) extends probe life and maintains accuracy in aggressive liquid environments.
• Flexible Mounting: Equipped with 1/8-inch standoffs for secure attachment to customer-supplied backplates.
• Direct Mode Operation: Relay energizes upon liquid contact, ideal for pump-down and alarm signaling logic.

• Can this be used for both pump-up and low-water cutoff? Yes, the Warrick Series DF allows the H/L terminals to manage a differential pump/valve function while the LLCO terminal provides dedicated safety monitoring.
• What happens during a power failure? The control de-energizes upon power loss. With the standard configuration, the output will automatically reset once power is restored if the liquid is at the appropriate level.
• Does this board require a special enclosure? Since this is an open-board design, it must be installed within a NEMA-rated enclosure or a grounded control cabinet to protect the circuitry from environmental contaminants.
