Warrick DFL1A0K040406 Circuit Board

Integrating the Warrick DFL1A0K040406 Circuit Board into your liquid handling or HVAC profile provides redundant, precise dual-function level control with industrial-grade reliability. This 120V open-board controller is engineered for conductivity-based liquid level sensing, utilizing a 10,000-ohm sensitivity rating to manage both single-level service and differential-level operations. Specifically configured for inverse acting operation, the board ensures the normally open contacts remain closed when the liquid is below the high-level probe, making it a staple for pump-up or high-level alarm applications.

The DFL1A0K040406 features built-in power outage reset and customizable time delays to eliminate relay chatter from turbulence or surface waves. For technicians performing maintenance in commercial boiler rooms or fluid management facilities, this OEM Warrick level control board offers a standard 1/16-inch standoff panel mount for rapid installation. Its solid-state design and 10A SPDT contact ratings ensure it handles industrial loads across HVAC level control and low-level cutoff (LLCO) systems with absolute consistency.

Key Benefits

• Dual-Function Logic: Simultaneously manages single-level and differential-level service, allowing for high-alarm and pump-up/down control on a single footprint.
• Field-Proven Reliability: Solid-state conductivity level control eliminates moving parts, reducing mechanical failure points in demanding fluid environments.
• Enhanced Protection: Integrated 6-second low-level cutoff (LLCO) delay prevents equipment dry-firing and pump cavitation during rapid level fluctuations.
• Versatile Mounting: Standard 1/16" panel mount standoff allows for immediate replacement in existing Warrick or Gems Sensors control enclosures.

Common Questions

How do I configure the DFL1A0K040406 for pump-up service?
Since this unit features inverse acting mechanism logic, it is inherently designed for pump-up applications where the pump starts when the level falls below the low probe and stops when it hits the high probe. Ensure your liquid conductivity is compatible with the 10K ohm sensitivity rating.

Will this board reset automatically after a power failure?
Yes, this model includes the power outage reset function, which allows the controller to resume normal operation and monitoring once power is restored, preventing manual intervention in remote or non-attended installations.

Can I use this for non-conductive fluids like oils?
No, Warrick conductivity-based controls require a conductive medium (such as water or chemicals) to complete the circuit between the probes. For non-conductive fluids, a float-type sensor or alternate technology is necessary.
