HI 6020IT and HI 6020JB Junction Boxes

Hardy HI 6020 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.

HI 6020IT and HI 6020JB

Junction Box and Summing Cards With or Without  Optional Integrated Technician
Stainless Steel Now with Class I, II, III, Div 1 or ATEX & IECEx Hazardous Certifications

The new 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 IT, trim pots (for non-Hardy load cells) and a NEMA 4X enclosure in stainless steel, painted steel or fiberglass. The enclosure features a thick-wall design with an interior seal for a long lasting, robust wash-down installation. Each box comes with six packaged hole plugs and six cable grip fittings suitable for load cell cables with an outside diameter of 1/4 to 3/8 inches.  The ATEX and IECEx (-EX models) are designed for installation with intrinsic barriers and do not come with any glands or hole plugs. 

A single HI 6020 Summing Box supports up to 4 load cells.  To connect two HI 6020 Summing Boxes together to support between 5 and 8 load cells, use the TB6 Auxiliary connection between boxes and order one of the summing boxes with six holes.
