Warrick 26NMB1A0 Control
The Warrick 26NMB1A0 Control is a professional-grade conductivity-based liquid level control designed specifically for boiler low water cutoff protection and industrial fluid management. This solid-state plug-in module utilizes a 10,000 ohm sensitivity rating, making it the ideal choice for sensing standard city water and liquids with moderate resistance. Built for reliability in demanding HVACR environments, the unit operates on a 120Vac supply voltage and features a direct acting mode of operation, ensuring that the internal SPDT relay energizes when the liquid reaches the probe and de-energizes when it recedes below the electrode.
Engineered for seamless integration, this 11-pin octal socket style controller is often used as a direct replacement component in steam boiler systems and condensate return tanks. The low water cutoff module provides critical dry-firing protection, meeting UL353 safety standards for limit controls. Its open-board plug-in design allows for rapid field installation and troubleshooting, while the screw connector socket ensures secure electrical terminations. With an ambient temperature rating of -40°F to 150°F, the Warrick 26NMB1A0 maintains high-precision performance across extreme mechanical room conditions.
Key Benefits for Contractors- UL353 Recognized: Specifically designed for low water cutoff protection to prevent boiler damage and dry firing.
- Plug-and-Play Installation: The 11-pin octal base allows for quick module replacement without rewiring the entire system.
- Robust SPDT Output: Features 10A resistive-rated dry contacts for controlling pumps, valves, or alarm circuits.
- Direct Acting Reliability: Standardized 10k ohm sensitivity provides steady performance in applications involving water treatment and cooling towers.
- Solid-State Design: No moving parts within the control module itself ensures superior longevity compared to mechanical float switches.
Is the Warrick 26NMB1A0 suitable for high-purity water applications?
With a 10,000 ohm sensitivity, this specific model is best suited for tap water and standard industrial fluids. For deionized or high-purity water, a higher sensitivity module (such as 26k or 50k ohm) is typically required to detect the lower conductivity.
How do I wire the SPDT relay for a high-level alarm?
Since this is a direct acting control, use the Normally Open (N.O.) contacts to trigger an alarm when the liquid hits the probe, or the Normally Closed (N.C.) contacts for applications requiring the load to drop out upon liquid contact.
Can this module be mounted outdoors?
The 26NMB1A0 is an open module with no enclosure. It must be installed inside a NEMA-rated junction box or control panel to protect the screw connector socket from moisture and contaminants.
