Warrick 26B1B0E Control

The Warrick 26B1B0E is a reliable conductivity-based liquid level control designed specifically for boiler low water cutoff protection in demanding commercial and industrial environments. Operating at 120Vac with a 10,000 ohm sensitivity, this direct-acting level controller ensures precise monitoring of conductive liquids. As a veteran-grade LWCO control board, the 26B1B0E features a single pole double throw (SPDT) relay, providing both normally open and normally closed contacts to manage burner circuits or alarm systems. This specific model, which is a direct replacement for Warrick 26B1B0E03, utilizes spade terminals for rapid field wiring and an 1/8" panel standoff style for secure mounting within an existing control cabinet. To prevent nuisance tripping from turbulent water conditions, it includes a built-in 3-second time delay. The manual reset with power outage feature is a critical safety component, ensuring the system remains offline after a low-water event until a technician confirms the boiler has returned to a safe operating state, even if power is momentarily lost.

• Fail-Safe Protection: The manual reset feature ensures the boiler stays down until a critical water level is restored, meeting stringent safety protocols.
• Turbulence Suppression: A integrated 3-second delay on decreasing level prevents rapid relay cycling caused by water surging or foaming.
• Universal Compatibility: Fully interchangeable with part number 26B1B0E03, facilitating seamless retrofits in standard Series 26 control applications.
• Industrial Durability: Solid-state design with 10A resistive contact ratings suitable for high-cycle environmental conditions.

How do I wire the manual reset on the 26B1B0E?
Standard manual reset wiring involves installing a normally closed (NC) pushbutton across the reset terminals. For this 120V liquid level control, the circuit will remain de-energized after a low-water trip until the operator manually engages the reset switch once the liquid has reached the probe again.

What is the difference between 26B1B0E and 26B1B0E03?
These two part numbers are identical in technical specification. The 26B1B0E serves as the current industrial standard for this direct acting 10K ohm configuration, maintaining the same spade terminal layout and low water cutoff logic as the 03 suffix variant.

Can this board be used in high-temperature boiler applications?
Yes, the Warrick Series 26 is rated for an ambient temperature range of -40°F to +150°F, making it a rugged choice for boiler room water level management.
