Warrick 16DMM1A0 Control

The Warrick 16DMM1A0 is a high-sensitivity liquid level control engineered for demanding applications requiring precise resistive sensing. Featuring a 26,000 ohm sensitivity and an inverse acting mode of operation, this module is optimized for low-conductivity fluids where the relay energizes upon liquid contact. Operating on a 120Vac supply voltage, the unit utilizes a DPDT (2 Normally Open/2 Normally Closed) relay configuration, providing versatile switching logic for both pump and alarm circuits. The 11 pin octal socket style ensures a secure, plug-in installation into standard screw connector sockets, facilitating rapid field replacement and minimizing downtime in industrial level monitoring systems. This general purpose plug-in module is designed for interior placement or protected enclosures, offering a compact footprint for complex control panels where reliable conductive level sensing is critical for process automation and equipment protection.

• High Sensitivity Logic: The 26,000 ohm threshold allows for accurate detection in water applications showing higher resistance levels.
• Inverse Acting Performance: Ideal for specific process requirements where the load must engage when the probe is submerged.
• Robust DPDT Switching: The double pole double throw relay allows for simultaneous control of a primary pump and a secondary remote alarm.
• Field-Proven Reliability: The series 16D platform is a standard in HVACR liquid control, ensuring compatibility with existing probe assemblies.
• Simplified Maintenance: The 11-pin octal base allows for tool-free module swaps once the screw terminal base is wired.

What is the maximum temperature rating for this control module?
The module is rated for ambient operating temperatures between -40°F and +150°F, though the specific probe hardware used in the tank will dictate the overall system temperature limits.

Can I use this for a low-water cutoff application?
Yes, provided the inverse acting logic matches your safety circuit requirements. The Warrick 16DMM1A0 is frequently specified for boiler feed and condensate recovery monitoring.

Does this unit require a specific mounting orientation?
As a plug-in general purpose module, it can be mounted in any orientation within an enclosure, though vertical orientation is preferred for 11-pin socket retention in high-vibration environments.
