Description
The Warrick-Gems Sensors & Controls 26MB1A0A is a precision liquid level control module engineered for reliable low water cutoff protection in boilers and hydronic heating systems. Designed as a convenient plug-in module with an 11-pin octal socket style, it installs quickly and integrates seamlessly with compatible relay bases — minimizing downtime and simplifying field replacement.
Operating in Direct Acting mode, the 26MB1A0A responds immediately to liquid level changes, making it an ideal safeguard against dry-fire conditions that can damage boiler heat exchangers. The SPDT relay with powered contacts provides both a Normally Open and a Normally Closed output, giving installers maximum wiring flexibility for a wide range of control circuit configurations.
Key Features
- 10,000 ohm (10KΩ) conductance sensitivity for reliable liquid detection
- Direct Acting mode of operation for immediate level response
- 120Vac supply voltage — compatible with standard commercial and residential power
- SPDT relay with powered contacts: 1 Normally Open / 1 Normally Closed output
- 11-pin octal socket plug-in style for fast, tool-friendly installation and replacement
- Low water cutoff functionality protects boilers from dry-fire damage
- Compact module design fits standard octal relay bases
Application
The 26MB1A0A is well-suited for boiler low water cutoff applications, condensate level monitoring, and other liquid level sensing tasks where conductance-based detection and a plug-in relay format are required. Its direct acting operation and SPDT output make it compatible with a broad range of hydronic and steam system control panels.
