As Series D, Revision H, this module integrates into the 1771 Remote I\/O family and provides the link between the PLC-5 processor and the remote 1771 I\/O modules, enabling distributed data flow across multiple racks. On the network, it handles addressing and data exchange to support distributed digital and analog I\/O, allowing the PLC-5 to read inputs and drive outputs from remote modules while centralizing control logic in the controller. The 1771-ASB D is designed for use with Allen-Bradley 1771 I\/O modules within PLC-5 Universal I\/O environments, aligning with the PLC-5 Remote I\/O (RIO) architecture and its backplane interface. Typical applications include manufacturing lines, packaging systems, and process-control installations where sensors, actuators, and auxiliary I\/O are distributed across remote racks but managed by a single PLC-5 system. \u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46244004561130,"sku":null,"price":187.0,"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-asb-d-remote-i-o-adapter-module","provider":"GTG Hardware","version":"1.0","type":"link"}
