1746-WS HARDY Weigh Scale Module self-contained microprocessor-based I/O module

Product Details

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 AB 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.
