Warrick 26MC1B0E Control

The Warrick 26MC1B0E is a high-sensitivity liquid level control designed specifically for low water cutoff applications requiring a manual reset. Operating on a 120Vac supply voltage, this 11-pin DIN mount plug-in module utilizes a 26,000 ohm direct acting mode of operation, making it ideal for sensing low-conductivity fluids in industrial boilers and hydronic systems. The SPDT relay features powered contacts (1 NO/1 NC), ensuring reliable signal transmission to burners or alarms. A critical feature for technicians is the power outage manual reset, which prevents automatic equipment restarts following a loss of utility power, enhancing system safety. This conductance-actuated control is housed in a compact module designed for internal panel mounting via the included screw connector socket, providing a rugged solution for precise boiler level monitoring without the need for a separate enclosure.

Key Benefits

• Enhanced Field Safety: The manual reset feature ensures the system remains locked out after a low-water condition or power interruption until a technician performs a manual override.
• Reliable Conductance Sensing: 26,000-ohm sensitivity allows for accurate detection in distilled water or low-solids applications where standard controls might fail.
• Streamlined Installation: The 11-pin plug-in design and DIN rail compatibility allow for rapid field replacement and reduced wiring time in control cabinets.
• Versatile Output: Powered SPDT contacts allow for direct integration with 120V control circuits, simplifying your wiring schematic.

Common Questions

How does the manual reset function during a power failure?
The 26MC1B0E is engineered to remain tripped if power is lost. Once power is restored, the unit requires a manual reset to resume normal operation, preventing unsafe dry-fire conditions.

Is this control compatible with high-temperature steam applications?
Yes, when paired with the appropriate 11-pin socket and remote conductive probes, this module serves as a primary or secondary low water cutoff for steam and hydronic boilers.

Can I use this with non-conductive liquids like oil?
No, as a conductance-based control, the 26MC1B0E requires a conductive medium (such as water or glycol) to complete the electrical circuit between the probes.
