Allen-Bradley 1756-2WS ControlLogix Hardy Dual Weigh Scale Module
Product Overview
The Allen-Bradley 1756-2WS is a specialized dual-channel weigh scale module designed for the ControlLogix® platform. Developed through a technology partnership with Hardy Process Solutions (formerly Hardy Instruments), this module allows for direct connection to strain-gage load cells without requiring external signal conditioners or transmitters.
By digitizing weight data directly on the 1756 backplane, the 1756-2WS ensures high-speed data throughput and eliminates the latency associated with traditional analog-to-digital converters. It features advanced vibration-filtering technologies and electronic calibration methods, making it the industry standard for high-precision weighing in automated batching, filling, and silo level monitoring systems.
