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. 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.
Super Easy Integration
- Free Add-On-Profiles
- Free Faceplate/AOIs for HMIs
- Direct Back-plane Connectivity
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).
Rockwell Add-On-Profile (AOP)
Quickly and easily configure the HI 1769-WS for your application through PLC software on a PC. A face plate makes the modules incredibly easy to use with common weighing functions built into the faceplate.

The Hardy Process Toolbox is a set of productivity tools that support industrial weighing functions. Each tool saves time, increases accuracy, improves efficiency, or reduces risk in process weighing applications, including WAVERSAVER® to eliminate vibration, C2® electronic calibration, and Integrated Technician® to name just a few.
The HI 1769-WS and 1769-2WS feature the following Toolbox technologies:
WAVERSAVER® Vibration Eliminator
Hardy's WAVERSAVER core technology eliminates the effects that surrounding vibration has on the scale weight signal, providing only true data for fast, accurate weight reading.
C2® (or eCAL) Electronic Calibration
The Hardy C2® (or eCAL as it is known in China) core feature provides quick and easy electronic calibration of a weighing system without the need for heavy test weights.
INTEGRATED TECHNICIAN® Operator Diagnostics
Hardy's INTEGRATED TECHNICIAN (IT) core feature helps you troubleshoot your weighing system and diagnose problems from the front of the instrument or via the PLC. These tests display system weights, voltages, and pass/fail displays to help isolate a problem to the instrument, cabling, or sensors, helping to reduce maintenance costs.
