It accepts 10–30 V DC input levels and provides 16 isolated field inputs, with 500 V DC isolation between the field circuits and the backplane to help protect the controller from voltage transients. This module plugs into a 1746 backplane rack and occupies a single I\/O slot, enabling straightforward mapping of 16 devices such as pushbuttons, limit switches, or proximity sensors to the CPU via the 1746 I\/O bus. As part of the SLC 500 family, the 1746-IV16 integrates with standard Rockwell Automation processors and supports typical SLC 500 scan operations, delivering reliable, deterministic input status to logic routines and control sequences. The product designation 1746-IV16 identifies a sixteen-point, 24 VDC input module within Allen-Bradley’s legacy automation line, making it a common choice for general-purpose DC input applications in manufacturing environments that rely on legacy SLC 500 hardware. This configuration is compatible with existing 1746 I\/O adapters and enclosures, providing a compact solution for expanding a controller’s sensing capabilities without upgrading the entire control system. \u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51658973970734,"sku":null,"price":29.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_397a13c2-340b-414a-b29e-9f59892b4c7e.jpg?v=1769526206","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1746-iv16-usnt-digital-input-module","provider":"PLG Automation ","version":"1.0","type":"link"}
