Hardy HI 1746-WS Weigh Scale Module


Hardy’s single-slot Rockwell® PLC/PAC modules read and condition data from strain gage load cells and communicate it over the I/O chassis backplane to the processor.

The only weight processor for the Allen-Bradley SLC 500 series!

The HI 1746-WS Weigh Scale Module is a self-contained microprocessor-based I/O module with control inputs and outputs.  The HI 1746-WS is designed to be easily plugged into the back plane of an Allen-Bradley SLC 5/02, 5/03, 5/04 or 5/05 programmable controller. The HI 1746-WS supports  a wide variety of process weighing applications such as batching/blending, filling/dispensing, check weighing, force measurement, level by weight and weight rate monitoring.

The module can control two (2) relays via two (2) TTL level outputs and transmits data via the backplane to the SLC.  A 20 bit A-D converter with 980,000 counts of display resolution gives the instrument the ability to tolerate large “dead” loads, oversizing of load cells/sensors and to provide accurate weight measurement and control.

To calibrate the module, simply push the front panel “Button” to effect a C2 calibration (electronic), or you can implement a C2,“Hard” (traditional with test weights) or “Soft (manual load cell data) through the processor.

The HI 1746-WS is IT-enabled, which means the module has a built in IT excitation monitor to detect load cell wiring problems, and with the addition of the optional HI 215IT Junction Box or HI 6010 Summing Box the user can use the other IT functions for fault isolation and troubleshooting of the weighing system. The optional Hardy HI WS100 configuration software makes for easy system setup.
