Developed in partnership with Hardy Process Solutions, this module enables the direct integration of industrial load cells and weigh scale platforms into the ControlLogix backplane. By providing two independent scale channels, the 1756-2WS enhances system density, allowing for the simultaneous monitoring of two separate vessels, silos, or platforms while minimizing the required rack space.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual-Channel Architecture:\u003c\/strong\u003e Independent processing for two separate scale platforms within a single ControlLogix slot.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-Resolution Conversion:\u003c\/strong\u003e Integrated high-resolution analog-to-digital converters for laboratory-grade weight data.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLoad Cell Compatibility:\u003c\/strong\u003e Supports up to eight 350-ohm Full Wheatstone Bridge strain gauge sensors, with a capacity of four load cells per channel.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdvanced Filtering:\u003c\/strong\u003e Utilizes Hardy's proprietary WAVERSAVER technology to electronically suppress mechanical and structural noise from plant machinery, mixers, or piping shock.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDirect Data Access:\u003c\/strong\u003e Provides weight data directly to the controller tag database for seamless integration into automation logic.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eApplications\u003c\/h3\u003e\u003cp\u003eThis module is ideal for high-precision industrial weighing applications, including batching, blending, inventory management, and force measurement.
