The LCI Load Cell Junction Box with Fault Monitoring is designed for the protection of multi-load cell installations such as silos, tanks and other systems where the failure of an individual load cell has to be detected and remedied before the serious consequences of overflow or incorrect production batching can occur. The device constantly samples the individual load cell channels and activates an alarm if any of several user-determined failure conditions are detected. For a simple summing circuit with no trimming and no corner compensation, use the Load Cell Junction PCB, model JPP Load Cell Junction PCB, and for trimming and corner compensation, use the Active Junction Box, model JBA Load Cell Junction Box.

Features & Benefits

• Accepts inputs from up to 4 x 350~1000 Ohm strain gauge load cells
• Plug-in field connectors for convenience during installation
• Electronics powered from load cell excitation - addt'l load equiv to 2 x 350 Ohm LC's
• Alarm via isolated volt free contacts for remote connection
• mV/V display of each individual load cell and of the summed total
• Display shows which load cell is at fault and gives fault type
• Output is the sum of the inputs - can replace any standard summing junction box

Alarm will be activated if:-

• One or more load cells are out of balance from pre-set error band
• Any load cell is operated outside of the preset mV/V range
• Excitation voltage deviates from preset range.
• Any connection is lost (open circuit detection)
• A short circuit is detected
