Warrick 16MB1B0 Control

The Warrick 16MB1B0 is a heavy-duty 120V AC conductivity level control designed for demanding industrial and commercial HVACR applications. Engineered by Gems Sensors & Controls, this general-purpose liquid level controller utilizes a plug-in 8-pin socket design for streamlined installation and field replacement. As a direct replacement for the 16MB1BO, it features an open-circuit board configuration and single-level service operation, making it ideal for high-resistance liquid sensing, steam boiler feed-water control, and pump-up/pump-down automation. The solid-state design ensures precision in detecting conductive liquids while providing consistent electromechanical relay output performance without the reliability issues of mechanical floats.

• Universal Compatibility: Direct drop-in replacement for legacy 16MB1BO models, ensuring seamless integration into existing control panels.
• High Sensitivity Range: Optimized for standard conducting liquids, providing reliable resistive bench sensing for accurate level monitoring.
• Industrial Build Quality: Features a rugged plug-in base for simplified wiring and 120V AC input voltage for standard electrical configurations.
• Versatile Control Logic: Supports multiple liquid level architectures including low-water cutoffs and high-level alarms in non-pressurized tanks.

Common Technical Questions

How do I wire the Warrick 16MB1B0 for a pump-down application?
Technicians should refer to the standard 8-pin schematic, utilizing the common and probe terminals to complete the circuit. This control is typically wired in series with the motor starter or contactor coil to manage liquid evacuation once the probe makes contact.

Is this control compatible with high-temperature environments?
This board is designed for ambient operating temperatures common in mechanical rooms. For high-temperature boiler applications, ensure the associated Warrick probe fittings and electrodes are rated for the specific steam pressure and temperature requirements of the vessel.

What is the difference between the 16MB1B0 and the 16MB1A0?
The primary difference is the input voltage and sensitivity settings. The 16MB1B0 is specifically rated for 120V AC operation. Always verify the secondary voltage at the transformer and the liquid resistance profile before selection to ensure the relay trips reliably.
