The LLC1 Series is a single probe conductive liquid level control designed for OEM equipment and commercial appliances. This device may be ordered in one of two modes: Fill or Drain. A factory fixed time delay (1-60s) prevents rapid cycling of the output relay. On adjustable units, the sensitivity allows accurate level sensing while ignoring foaming agents and floating debris. Transformer isolated 12 V AC is provided at the probe to prevent electrolysis. A trickle current of less than 1 mA determines the presence or absence of liquid between the probe and common. The LLC1 Series printed circuit board is conformal coated to resist moisture and corrosion.
