Warrick 26MC1A0E Liquid Level Control

The Warrick 26MC1A0E is a precision-engineered liquid level control module designed for high-sensitivity low-water cutoff applications in HVACR and industrial process systems. Operating on a 120Vac supply voltage, this 11-pin octal socket plug-in module utilizes a 26,000 ohm direct acting mode of operation, ensuring reliable conductivity sensing in various fluid environments. The integrated SPDT relay features powered contacts (1 NO/1 NC), facilitating seamless integration into existing control circuits for pump or valve management. A critical feature for safety-compliant installations, the manual reset with power outage feature prevents automatic equipment restarts after a power failure or low-water condition, protecting boilers and chillers from dry-fire scenarios. This open-board module requires no enclosure and connects via a screw connector socket, making it a standard replacement for professional contractors maintaining liquid level monitoring systems. Its compact design and robust sensitivity make it ideal for non-conductive tanks or systems requiring high-impedance sensing.

• Enhanced Safety: The manual reset lockout ensures a technician must inspect the system before resuming operation after a trip.
• Versatile Switching: The SPDT relay with powered contacts simplifies wiring for both alarm and control functions.
• Reliable Sensing: 26K ohm sensitivity allows for accurate detection in fluids with varying conductivity levels.
• Easy Maintenance: The 11-pin octal plug-in design allows for rapid field replacement without re-wiring the entire socket base.
• Compact Footprint: Ideal for integration into existing control panels where space is a premium.

How do I wire the Warrick 26MC1A0E for low water cutoff?
The module utilizes an 11-pin base where the probe and ground leads are connected to specific terminals. The SPDT relay terminals provide the dry contact or powered output needed to break the burner or pump circuit upon a low-level event.

What is the purpose of the 26,000 ohm sensitivity rating?
This high-impedance threshold allows the controller to sense liquids that have lower conductivity, preventing false trips or failure to detect level changes in cleaner water or specific chemical solutions.

Does the manual reset feature persist after a power flash?
Yes, the manual reset circuitry is designed to stay in the lockout position even if power is cycled, requiring a physical button press to clear the state once the liquid level is restored.
