Warrick 26MC1A0F 11 Pin Octal

The Warrick 26MC1A0F is a robust conductivity-based liquid level control explicitly engineered for industrial applications requiring reliable boiler low water cutoff (LWCO) protection. Built as a solid-state plug-in module, this 11-pin octal series 26 control meets rigorous CSD1 safety requirements, making it a standard choice for veterans maintaining steam and hot water systems. Operating on a 120 VAC supply, the unit features powered contacts and a factory-set sensitivity of 26K ohms, ensuring precise detection in moderately conductive fluids. With its modular Lexan housing, this controller integrates seamlessly into existing panels using a standard A-11 socket, providing a secondary probe circuit of 12 VAC to minimize electrode scaling and electrolysis.

Designed for direct-acting operation, the 26MC1A0F includes a built-in manual reset feature. If the liquid level drops below the electrode threshold, the control de-energizes and locks out, preventing the system from restarting until the level is restored and an operator intervenes. This provides a critical safety interlock against dry-firing conditions in boiler vessels. The SPDT relay configuration (1 NO / 1 NC) is rated for 10A resistive loads at 120/240 VAC, allowing for direct control of burners or high-level alarms. With a standard 3-second time delay on decreasing levels, the Warrick 26M series effectively filters out nuisance trips caused by turbulence or surging within the tank.

• CSD1 Compliance: Meets essential safety standards for boiler limit controls and low-water protection.
• Solid-State Reliability: No moving parts within the control module reduces mechanical failure points.
• LED Diagnostics: On-board LED provides real-time status monitoring and blinks specific fault codes for rapid troubleshooting.
• Integrated Manual Reset: Ensures a technician must verify the system after a low-water event before operation resumes.
• Rugged Temperature Range: Rated for ambient operation from -40°F to 150°F, suitable for demanding mechanical rooms.

• Can I use this with non-conductive liquids like oil? No, this is a conductivity-based relay. It requires a conductive medium to complete the circuit between the probe and the tank wall or reference electrode.
• Does it work with existing Warrick probes? Yes, it is compatible with standard Warrick fittings and electrodes. For new installs, ensure you use #14 or #16 AWG wire for probe connections.
• What happens if there is a power outage? This model features a power outage recovery logic that ignores brief power losses, preventing unnecessary manual resets if liquid is still present on the probe when power returns.
