Small size, high performance!

Hardy HI 1769-WS and -2WS are single channel PLC-style weigh scale  modules for use with the Allen-Bradley MicroLogix® 1500 and CompactLogix® controllers.

Super Easy Integration

  • Free Add-On-Profiles
  • Free Faceplate/AOIs for HMIs
  • Direct Back-plane Connectivity

The HI 1769-WS and -2WS reads and conditions weight and diagnostic data from strain gauge load sensors or load cells up to one hundred times per second and communicates this data over the I/O chassis backplane to the PLC 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.

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 WS module supplies 5 volts of DC excitation to drive up to four 350-ohm load sensors or load cells associated with a single scale. The 2WS supports up to eight 350-ohm load cells with two scales.  Both will support additional load cells with an external power supply.

The HI 1769-WS incorporates Hardy Process Toolbox core features of
WAVERSAVER®, C2® electronic calibration INTEGRATED TECHNICIAN® (IT).
