Warrick 16MB1A0 Control

The Warrick 16MB1A0 is a heavy-duty single-level plug-in liquid level control designed for reliability in demanding commercial and industrial HVACR environments. Engineered as a 10,000 ohm sensitivity module, this direct-acting control ensures precise monitoring for condensate recovery, boiler feed-water systems, and sewage applications. Operating on 120Vac supply voltage, the unit features an SPDT relay (1 NO/1 NC) for versatile switching logic. The compact 8-pin octal socket design allows for rapid field replacement and minimizes downtime during service calls. As a general purpose plug-in module, it interfaces seamlessly with standard probe assemblies to manage conductive liquids via solid-state circuitry. This model is characterized by its high-voltage isolation and robust build quality, providing stable performance in high-temperature or high-vibration settings where conductance-actuated control is required for system safety and automation.

• Streamlined Installation: The octal plug-in base facilitates fast mounting onto standard 8-pin screw connector sockets, reducing labor time.
• High Sensitivity Calibration: Fixed 10,000 ohm sensitivity makes this unit ideal for general water-based applications and moderate conductivity fluids.
• Direct-Acting Performance: Ensures the internal relay de-energizes when liquid levels drop below the probe, protecting pumps and preventing dry-firing.
• Compact Footprint: The no enclosure plug-in module fits easily into existing control panels where space is a premium.

What is the difference between direct-acting and inverse-acting on the Series 16?
Direct-acting models like the Warrick 16MB1A0 de-energize the relay when liquid leaves the probe, making them the standard choice for low-level cutoff and pump-dry protection.

Can I use this control with any probe?
Yes, it is compatible with standard Warrick 3C, 3E, and 3W probe assemblies, provided the liquid resistance remains within the 10,000 ohm threshold.

How do I verify the sensitivity match for my application?
Check the fluid's conductivity; a 10K ohm unit is optimized for city water and most HVAC condensate, but may require a higher sensitivity model for ultrapure water or distilled liquids.
