Allen-Bradley 1756-2WS Dual Weigh Scale Module

The Allen-Bradley 1756-2WS Dual Weigh Scale Module (sold in Hardy’s line as the HI 1756-2WS) is a dual‑channel weight measurement module that mounts directly into a ControlLogix chassis for precise, on‑rack weighing. It provides eight weigh inputs (load cells/points) across two independent channels, with 5 VDC excitation capable of driving up to eight full Wheatstone-bridge load cells (four per channel). The module’s analog‑to‑digital converter updates at 50 samples per second and offers a resolution of 1 in 8,388,608, enabling stable, high‑precision weight readings for applications such as batching, blending, filling/dispensing, level-by-weight, and check weighing. Designed for strain‑gauge load cells, the HI 1756‑2WS integrates with the ControlLogix backplane to deliver reliable, dual‑channel weighing within typical process‑control environments.
