Product Overview
The HI 1769-WS is a specialized, single-channel weigh scale module manufactured by Hardy Process Solutions for seamless integration into Allen-Bradley CompactLogix and MicroLogix 1500 systems. This module eliminates the need for standalone weight transmitters by providing a direct interface between strain-gauge load cells and the PLC backplane. Designed for high-precision industrial weighing, the HI 1769-WS features Hardy’s proprietary C2® electronic calibration and WAVERSAVER® technology, which filters out plant vibration to provide stable, accurate weight data. By processing weighing signals at the controller level, it reduces system latency and wiring complexity in high-speed batching and filling applications.
