Description
The Warrick-Gems Sensors & Controls 26MB1A0F is a precision-engineered liquid level control module designed for low water cutoff applications in boilers and hydronic heating systems. Built for reliable, direct-acting performance, this plug-in module delivers dependable protection against low water conditions that can cause costly equipment damage or unsafe operation.
Featuring an 11-pin octal socket-style plug-in design, the 26MB1A0F installs quickly into compatible relay bases without the need for hardwiring directly to the control — simplifying installation, maintenance, and field replacement. The SPDT relay with powered contacts provides both a normally open and normally closed output, giving system designers flexibility in control circuit configuration.
Key Features
- Direct acting mode of operation for immediate response to low water conditions
- 10,000 ohm (10KΩ) operating resistance for accurate liquid level sensing
- 120Vac supply voltage for compatibility with standard commercial and residential electrical systems
- SPDT relay output — 1 Normally Open (NO) / 1 Normally Closed (NC) — with powered contacts
- 11-pin octal socket plug-in style for fast, tool-friendly installation and replacement
- Low water cutoff functionality protects boilers and hydronic equipment from dry-fire damage
- Compact plug-in module design simplifies service and reduces downtime

Application
The 26MB1A0F is ideal for use in commercial and industrial boiler systems, hydronic heating equipment, and other liquid-level monitoring applications where a reliable, low-resistance sensing circuit is required. The direct-acting relay design ensures the load circuit de-energizes when the liquid level drops below the sensing probe — providing a critical safety shutoff to protect heating equipment and building occupants.
