The advanced LCI fault monitoring load cell junction box delivers continuous and immediate alarm and fault monitoring for up to 4 strain gauge based transducers providing increased safety and costs savings. This LCI fault monitoring junction box is fantastic for multi-load cell applications as it can monitor the millivolt signals from each load cell making sure they all match. Typical applications include weighing platforms, weighbridges and vessel weighing systems.

The LCI continually monitors each individual load cell and activates an alarm when faults in the system are detected. The red 4 digits LED display shows a code that tells you which load cell is at fault and what the fault is enabling fast repairs to be carried out with minimal downtime. This also prevents batch wastage, overflow and material shortage due to a failure of an individual load cell.

The LCI fault monitoring load cell junction box uses the same excitation supply of the connected instrumentation so it does not need any additional power cables. It also now supports both 5Vdc and 10Vdc supply for lower power consumption.

The LCI fault monitoring load cell junction box can be supplied in an IP65 ABS field case with six M16 cable glands, making the LCI suitable for use in harsh environments requiring a sealing rating up to IP65.

For applications where the only interconnection is required, the passive AMLJBNA load cell junction box offers a lower-cost option.
