there are n load cell inlets and an n-channel a/d module in each hirs-n (n-channel) digital weighing junction-box, which can process each channel signal and output signals separately, or do the processing at one time and output signals in serial to the bus. in addition, angular difference adjustment can be done in the junction-box.
application: especially for muti-channel hopper/tank weighing, digital truck scale, industrial process weighing instruments.
