JBA Active Load Cell Junction Box

JBA.

Features

  • Improves overall system accuracy in weighing systems
  • Combines corner correction with load cell termination
  • Simple adjustment procedure
  • Robust IP65 enclosure
  • Ideally suited for use with the ADW15, SMW and LCA15

The function of the JBA active load cell junction box is to enable easy adjustment of load cell (output) manufacturing tolerances without any channel interaction, to give a summated output.

Features
The JBA Junction Box is used to sum the outputs from up to four load cells to allow them to be connected to the LCA15/ADW15 Strain Gauge Indicator/Controller.

The individual channel gains can be set up via DIL switches and preset potentiometers to allow for 2, 3, or 4 load cells.

Gain is not interactive and offset is preset, to speed up matching of the load cell gain.
