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 Hardy HI 6020 Summing box is a critical component in a weighing system that enables the 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.  Hardy has added a lock to the front of stainless steel enclosures that permit a tight seal without using screws. 

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.

The HI 6020 Junction Box is UL and CE compliant and is rated for installation in Hazardous Locations:

The Hardy Process Toolbox is a set of productivity tools that support industrial weighing functions. Each tool saves time, increases accuracy, improves efficiency, or reduces risk in process weighing applications, including C2® electronic calibration, and Integrated Technician® to name just a few.

Hardy load cells support the following Hardy Process Toolbox functions when coupled with a Hardy Instrument and Hardy C2® cable.

C2® (or eCAL) Electronic Calibration

The Hardy C2® (or eCAL as it is known in China) core feature provides quick and easy electronic calibration of a weighing system without the need for heavy test weights.

INTEGRATED TECHNICIAN® Operator Diagnostics

Hardy's INTEGRATED TECHNICIAN (IT) core feature helps you troubleshoot your weighing system and diagnose problems from the front of the instrument or via the PLC. These tests display system weights, voltages, and pass/fail displays to help isolate a problem to the instrument, cabling, or sensors, helping to reduce maintenance costs.
