Electronic weigh module

Hardy Instruments’ HI 1769-WS is a single channel PLC-style weigh scale module for use with the Allen-Bradley MicroLogix® 1500 and CompactLogix® controllers. The HI 1769-WS reads and conditions weight and diagnostic data from strain gauge load sensors or load cells and communicates this data over the I/O chassis backplane to the MicroLogix® 1500 or CompactLogix® processor. The HI 1769-WS module reduces installation costs, as it needs no external stand-alone scale instrument with a wired communications link to the PLC.

The HI 1769-WS conditions and digitizes the weight signal one hundred times per second with more than eight million counts of resolution over a differential signal range of 0 to 15mV. It then transmits the selectable Gross, Net, Tare and/or Diagnostics data to the processor. This high resolution enables the module to tolerate large dead loads and over sizing of the load sensors, while retaining a high level of usable resolution.

The module supplies 5 volts of DC excitation to drive up to four 350-ohm load sensors or load cells associated with a single scale. It will support additional load cells with an external power supply
