Warrick 16B1A0 Control

The Warrick 16B1A0 is a high-performance liquid level control board engineered for precision in demanding HVACR and industrial pump applications. Operating on a 120Vac supply voltage, this direct-acting level control utilizes a 10,000 ohm sensitivity threshold to manage conductive liquids via conductive probes. The unit features an SPDT (Single Pole Double Throw) relay, providing one normally open and one normally closed contact for versatile field wiring. This open board liquid level control is designed with 1/16-inch panel standoffs and spade terminals, facilitating rapid integration into existing control panels without the need for additional enclosures. Its solid-state design ensures reliable boiler feed and condensate return management. As a Series 16 board, it serves as a robust point level controller compatible with a wide array of Warrick electrode assemblies. Experienced technicians rely on this induction relay for its consistent performance in low-water cutoff and high-level alarm systems.

• Direct-Acting Operation: Ensures immediate relay activation when liquid contacts the probe, ideal for tank filling and level monitoring.
• Industrial Build Quality: The general-purpose open board configuration allows for efficient heat dissipation and clear access to wiring terminals.
• Application Versatility: Suited for sewage lift stations, food processing, and chemical feed systems requiring medium sensitivity (10k ohms).
• Simplified Installation: Features integrated standoffs and standard spade connections to reduce labor time during retrofit or new build-outs.

How do I wire a Warrick 16B1A0 for high-level alarm applications?
For high-level sensing, the 120V power is applied to terminals 1 and 2, while the sensing probe is connected to terminal H. The SPDT contacts (terminals 3, 4, and 5) are then utilized to trigger the external alarm or shut down a pump when continuity is established through the liquid.

Can the 10,000 ohm sensitivity be adjusted in the field?
The 16B1A0 is a fixed-sensitivity control board. If your application involves high-purity water or specific chemicals requiring different resistance thresholds, verify that 10,000 ohms matches the conductivity of the fluid being monitored.

Is this control board compatible with existing Series 16 enclosures?
Yes, this 1/16" standoff style board is the standard replacement module for Series 16 open-style configurations and can be mounted within existing NEMA-rated enclosures provided for these systems.
