Warrick DFL1A0Z-04-04-15 Control

The Warrick DUAL FUNCTION LEVEL CONTROL (model DFL1A0Z-04-04-15) is a robust conductivity-based liquid level control board designed for heavy-duty industrial and commercial applications, including feedwater control and low-water cutoff. This open-board module operates on a 120 VAC supply voltage and features dual-function logic that allows for simultaneous single-level and differential-level management. Engineered for precision, the unit provides solid-state reliability with a 10K ohm sensitivity calibration, making it ideal for sensing conductive liquids in process tanks, boilers, and chemical systems.

Built to handle rigorous environments, the Warrick DFL1A0Z-04-04-15 supports UL 353 limit control standards and includes integrated time delays and a manual reset function. The spade terminal layout ensures straightforward wiring for technicians, while the inverse mode operation and 10 Amp resistive contact rating provide versatile integration with pumps and solenoid valves. With a wide operating temperature range of -40°F to 150°F, this level control board maintainses performance consistency in demanding HVACR and process cooling infrastructures.

• Dual-Function Versatility: Manages independent high/low differential and low-water cutoff cycles from a single Series DF board.
• Enhanced Safety: Built-in manual reset and power outage features ensure the system remains locked out after a critical low-level trip.
• High-Load Capacity: Features SPDT contacts rated for up to 1/3 HP at 120/240 VAC, suitable for direct motor or alarm control.
• Reliable Sensing: Utilizes AC current on the probes to minimize electrolysis and extend electrode service life.

What is the difference between direct and inverse mode on this control?
The Warrick DFL1A0Z-04-04-15 uses inverse mode, meaning the relay energizes when the liquid level falls below the probe, typically used for pump-up or refill applications to prevent dry-running equipment.

Can this be used with standard 1/4-inch spade connectors?
Yes, the board features 1/4-inch male spade terminals for power and line connections, and 3/16-inch terminals for probe inputs to prevent cross-wiring errors during installation.

Does this board require a specific enclosure?
This is an open-board design intended for mounting within a protected control panel or NEMA-rated enclosure using the provided standoffs.
