Developed in partnership with Hardy Process Solutions, this module enables the direct integration of industrial load cells and weighing platforms into the ControlLogix backplane. By eliminating the necessity for external weight transmitters or signal conditioners, it streamlines system architecture for critical weighing tasks such as batching, filling, vessel monitoring, and force measurement.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eDirect interface for up to four 350-Ohm load cells per channel.\u003c\/li\u003e\n\u003cli\u003eHigh-speed processing with an update rate of 50 updates per second.\u003c\/li\u003e\n\u003cli\u003eExceptional measurement precision with a non-linearity rating of 0.0015% of Full Scale.\u003c\/li\u003e\n\u003cli\u003eSeamless integration into the ControlLogix backplane for direct data exchange with the controller.\u003c\/li\u003e\n\u003cli\u003eRobust design for industrial environments with an operating temperature range of 0 to 60 degC.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eApplications\u003c\/h3\u003e\u003cp\u003eThe 1756-WS module is optimized for industrial weighing environments requiring high accuracy and repeatability.
