LLA: Dual High-Low Alarm Relay
• Conductive or Float
Switch Inputs
• Dual Alarm Operation
• 5K to 100KΩ Sensitivity,
Adjustable
• Low AC Sense Voltage
• 10 Amp Contacts
• Noise Filter
• Nusance Delay
Operation
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.
