The Hardy HI 1769-WS Weigh Scale Module is an advanced solution from Hardy Process Solutions, tailored for the Allen-Bradley MicroLogix 1500 and CompactLogix controllers. This single-channel module eliminates measurement disruptions with its WAVERSAVER feature, filtering out vibrations below 0.25 Hertz for accurate readings. It processes weight data 110 times per second with over 8 million counts of resolution over a 0 to 15 millivolt differential, powered by a 5V DC excitation for up to four 350-ohm load cells. Additionally, its Integrated Technician feature, used with an IT Junction Box, streamlines diagnostics and troubleshooting to ensure efficient system performance. Engineered for demanding industrial environments, it operates within a broad temperature range of 0 to 60 degrees Celsius and maintains reliability across various standards, including UL/CUL, CE, and Class I, Div 2 approvals.
