Liquid Level Control provides low liquid cutoff protection.

Press Release Summary:



LLC6 Series plug-in, single probe control uses small ac current to sense presence of conductive liquid in tanks. It offers factory fixed time delay of 1 to 60 sec and is available for input voltages of 24, 120, or 230 Vac, 50/60 Hz. Rated 10 A resistive at 240 Vac, SPDT relay contacts are isolated from operating and probe voltages. Unit is available with manual/automatic reset or manual reset with power outage feature that ignores nuisance outages.



Original Press Release:


Low Level Cutoff Liquid Level Control LLC6 Series


ABB is pleased to announce a new addition to the SSAC
brand of conductive liquid level controls, the LLC6 Series.

The LLC6 Series is a low cost plug-in single probe liquid level
control designed for low liquid level cutoff protection. Low level cutoff protection is normally used in equipment and commercial appliances that produce hotwater or steam, like boilers and steamers. Low level cutoff protection helps prevent thermal runaway and excessively high internal pressure in the hot water tank by disconnecting the heating element if the water level is too low. A probe is installed in the hot water tank. As long as the water is in contact with this probe the heating element can operate. The LLC6 uses a very small AC current to sense the presence of the water in the tank. The LLC6 is designed for systems that use conductive liquids, like water.

This series offers a factory fixed time delay of 1 to 60 seconds and is available for input voltages of 24,120, or 230 VAC, 50/60 Hz. The sense resistance is factory fixed from 5K to 250K.

The LLC6's SPDT relay contacts are isolated from the operating and probe voltages. Rated 10 amps resistive at 240 VAC, they can switch small pumps, valves, or pump contactors. An LED indicator turns on when the relay is energized.

The LLC6 is available with manual/automatic reset or a special manual reset with a power outage feature that ignores nuisance outages. The 24 and 120 VAC units are UL recognized as limit switches under UL353 (230 VAC units are UL508) and CSA certified under CSA Standard 14. These devices are also CE approved.

The LLC6 Series' cost effective 11 pin plug-in design and UL353 recognition makes it perfect for low level cutoff protection in boiler applications.
