Each channel accepts a 120V signal (AC or DC) and preserves galvanic isolation from the backplane to resist noise and transients in industrial environments. Designed to plug into a 1771 I\/O chassis, the 1771-ID A integrates with the PLC-5 family and supports common sensing devices such as pushbuttons, limit switches, and proximity sensors. Its isolated input design and compatibility with legacy 120V sensing circuits make it a straightforward choice for retrofits or expansions of existing PLC-5 installations.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"New Surplus No Box","offer_id":46244008165610,"sku":null,"price":140.0,"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-id-a-isolated-input-module","provider":"GTG Hardware","version":"1.0","type":"link"}
