LLA: Dual High-Low Alarm Relay


• Conductive or Float

  Switch Inputs


• Dual Alarm Operation


• 5K to 100KΩ Sensitivity,



• Low AC Sense Voltage


• 10 Amp Contacts


• Noise Filter


• Nusance Delay


Dual Seal or Temp Stat Failure

The LLO/C accepts inputs that are either conductivity (resistance) and/or normally closed temp-stat contacts. Internal logic circuitry determines the alarm condition.


Seal Failure: Low reisitance sensed on either input

Temp Stat Failure: Open contact on either input


Diagnostic LEDs indicate the input generating the fault and output relay state.
