This Series C card accepts 120 V AC or DC input signals and provides reliable digital state feedback to the controller, making it well-suited for wiring sensors, limit switches, and other on\/off devices in automation lines. The module draws up to 75 mA at 120 V and is intended for use with 1771 I\/O racks, where it plugs into the standard backplane to extend the controller’s input capability; typical applications include conveying systems, packaging lines, and machine safety interlocks. As a genuine Allen-Bradley part cataloged as 1771-IA, it integrates with existing 1771 backplanes and supports the broad ecosystem of 1771 I\/O modules.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46244006232298,"sku":null,"price":217.0,"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-ia-usntc01-programmable-logic-controller","provider":"GTG Hardware","version":"1.0","type":"link"}
