The LLC8 series is a low cost, single-probe, conductive liquid level control designed for low liquid level cutoff protection. It offers a factory-fixed time delay of 1-60 s and is available in input voltages of 24, 120, or 230 V ac. An LED indicator illuminates whenever the LLC8's isolated, 10 A, SPDT output relay is energized. The sense resistance is fixed from 5 k-250 kΩ. The LLC8 series is available with a manual/automatic reset or a special manual reset with a power outage feature that auto-resets the unit when power is restored, and the water level is acceptable. 24 and 120 V ac units are UL recognized as limit switches under UL 353 (230 V ac units are UL 508) and CSA certified under Standard 14. The printed circuit board is conformally coated to resist moisture and corrosion.

See datasheet for operation and reset (automatic reset, manual reset, power outage manual reset) details.
