Introduction to the HI 6020IT and HI 6020JB Summing Boxes 

The Hardy HI 6020 summing box is a critical component in a weighing system that enables use of Hardy’s core 

technologies - C2

®

 electronic calibration and Integrated Technician

® 

(IT).   

 

Each  summing  box  distributes  excitation  voltage  to  up  to  four  load  cells  and  transfers  each  load  cell’s 

performance characteristics and  weight  signals to the Hardy  weighing instrument.  A  summing card  with IT 
allows a weighing instrument operator to switch to the summing card’s internal test circuit and diagnose the 
entire weighing system from the front panel of the instrument or a remote location over the Internet.   Individual 

load cells can be isolated from each other for weight and voltage readings, allowing a technician or operator to 

quickly and safely troubleshoot weighing system faults and anomalies. 

 

 

The HI 6020 Summing box is available with a variety of options, including Integrated Technician

® 

(IT) and 

trim pots (for non-Hardy load cells). The UL Type 4/4X stainless steel enclosure features a thick-wall design 

with an interior seal for a long lasting, robust wash-down installation. Two configurations are available, a 5-

hole version for connecting up to four load cells to a Hardy weight indicator, controller, or module; or a 6-

hole version that connects to a second HI 6020 summing box to enable up to eight load cells to be connected 

to a Hardy weight indicator or controller.
