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.
