The LLC6 series is a plug-in, 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 LLC6’s 10 A, SPDT output relay is energized. This unit is available with automatic/manual 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 V ac and 120 V ac units are recognized as limit switches under UL353 (230 V ac units are UL508) and CSA certified under Standard 14. The LLC6 series features an industry standard 11-pin octal plug connection.

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

Features

  • Isolated 12 V ac voltage on probe
