Hardy's offers both general and application specific PLC-style weigh scale modules for use with the Rockwell Automation® MicroLogix™ 1500 and CompactLogix™ controllers. These modules read and condition 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 modules reduces installation costs, as it needs no external stand-alone scale instrument with a wired communications link to the PLC.
Hardy plug-in-modules condition and digitize 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.
Hardy weight modules incorporate the Hardy Process Toolbox core features of WAVERSAVER®, C2® electronic calibration, and INTEGRATED TECHNICIAN® (IT). Add-On-Profiles for the ControlLogix modules make integration into industrial weighing applications seamless.
