Relays Liquid Level Relays
LL   Liquid Level Control Relay - LL Series

The LL Series Relay is a factory configurable multi-purpose device capable of sensing conductive non hazardous fluids with low voltage contact probes.  It has five factory settable modes of operation:

  • LLF - Liquid Level Fill control
  • LLD - Liquid Level Drain control
  • LLA - Dual High/Low Alarm or Simplex Seal and Temp Stat Failure Relay
  • LLO - Dual Seal Failure Relay
  • LLC - Dual Temp Stat Failure Relay

In addition to the five operational modes listed above, it has four supply voltage range models:

  • 12A :     11  to 16VAC
  • 24A :     20 to 29VAC
  • 120A :   100 to 125VAC
  • 240A : - 200 to 240VAC

Provides relay latching for tank fill or drain operations. Adjustable sensitivity.  Multiple operation options.

  • Pumps or Compressors
  • Level sensing (Float or Probe)
  • Combustible or Hazardous locations
  • Simplex pumping
  • Liquid Level Sensing The LL F/D/A/O/C senses conductive non hazardous fluids with low voltage contact probes. Internal logic circuitry controls the relay latching for tank Fill or Drain operations. Three diagnostic LEDs indicate the input and output relay states. The sensitivity is adjustable to control effects of liquid wickers from the level probes. The Alarm version operates as a Dual High and Low Level Alarm or it may be operated as either a High or Low Alarm. A delay timer reduces wave effects.
