Warrick 16C1B0 Level Control

The Warrick 16C1B0 is a high-sensitivity conductive liquid level control engineered for precision applications requiring a 26K Ohm-cm sensitivity threshold. Operating on 120V AC, this Series 16M plug-in controller utilizes a single-pole double-throw (SPDT) contact configuration to facilitate reliable low-water cutoff, high-level alarm, or pump control functions. Designed for DIN-rail mounting, the 16C1B0 features an 11-pin octal base, making it a standard drop-in replacement for industrial boiler feed systems and wastewater monitoring panels. Its solid-state design eliminates the mechanical failure points common in float switches, while the UL-recognized and CSA-certified internal circuitry ensures stable switching even in environments with moderate foam or turbulence. Technicians should verify that the probe voltage and current specifications align with existing level sensor electrodes to maintain optimal electrolytic balance and prevent electrode fouling during long-term operation.

Key Technical Benefits

• 26K Ohm Sensitivity: Optimized for standard tap water and mildly conductive liquids.
• Modular Design: 11-pin plug-in controller format allows for rapid field replacement without rewiring the base.
• SPDT Contacts: Rated for pilot duty, providing versatile integration for normally open or normally closed logic.
• Industrial Durability: Engineered to withstand the electrical noise and thermal fluctuations typical of HVACR mechanical rooms.
• Encapsulated Circuitry: Protects internal components from moisture and vibration in high-demand environments.

Common Questions for Technicians

Can the 16C1B0 be used for sewage or high-debris applications?
While the 26K Ohm sensitivity is suitable for many water-based liquids, high-debris environments may require secondary filtration for the electrodes to prevent false triggering from conductive sludge buildup.

How do I test the switching logic during commissioning?
With the unit powered, you can simulate a level condition by bridging the electrode terminals with a resistor matching the 26K Ohm spec to confirm relay activation and contact continuity.

Is this unit compatible with secondary remote alarms?
Yes, the SPDT relay output can be wired to simultaneously control a pump starter and a remote monitoring signal or BMS input.
