This module plugs into a standard 1771 I\/O rack and maps its 16 inputs to the PLC’s input image, enabling straightforward wiring of pushbuttons, limit switches, and other field devices. Each channel accepts a 24V AC digital input and reports a reliable boolean to the processor for fast state monitoring. As part of Rockwell’s 1771 I\/O family, the 1771-IND is designed to work with typical PLC-5 and SLC-500 workflows, commonly used in manufacturing lines and automated machinery. The 16 discrete input points support scalable wiring for multi-sensor configurations, and the module is designed to operate with the backplane architecture and configuration tools used for PLC-5-based systems. When paired with compatible output modules and logic processors, the 1771-IND enables synchronized control logic, ladder diagrams, and sequencing across an automation cell. A compact, plug-in solution for expanding digital input capacity, the 1771-IND helps teams monitor external conditions—interlocks, sensors, and other discrete signals—without redesigning existing control architectures.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"New","offer_id":46244009672938,"sku":null,"price":145.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-079.png?v=1788727429","url":"https:\/\/gtghardware.com\/products\/allen-bradley-1771-ind-slc-500-digital-input-module","provider":"GTG Hardware","version":"1.0","type":"link"}
