LLC1 Series Information

  • Single Probe Level Control for Conductive Liquids
  • Isolated AC Voltage on the Probes
  • Adjustable or Fixed Sensing up to 250kOhms
  • Fill or Drain Operations Available
  • Isolated, 10A, SPDT & Non‑Isolated, SPST Output Contacts
The LLC1 Series is a single probe conductive liquid level control designed for OEM equipment and commercial appliances. This unit may be ordered with selectable or fixed fill or drain operation. A time delay (1‑60s) prevents rapid cycling of the output relay. On adjustable units, the sensitivity adjustment allows accurate level sensing while ignoring foaming agents and floating debris. Isolated AC voltage is provided at the probe to prevent electrolysis. A trickle current of less than 1mA 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.

Drain (Pump‑Down Mode): When the liquid level rises and touches the probe, a fixed time delay begins. This time delay prevents rapid cycling of the output relay and its load. At the end of the time delay, the output relay energizes and remains energized until the liquid level falls below the probe. The output relay then de‑energizes and remains de‑energized until the liquid again touches the probe.

Fill (Pump‑Up Mode): When the liquid level falls below the probe, a fixed time delay begins. This time delay prevents rapid cycling of the output relay and its load. At the end of the time delay, the output relay energizes and remains energized until the liquid level rises and touches the probe. The output relay then de‑energizes and remains de‑energized until the liquid level again falls below the probe.
