As an eight-wide backplane, it provides space for a mix of 1771 I\/O cards and has external dimensions of roughly 35.6 cm (length) × 34.1 cm (width) × 3.05 cm (height). The chassis is used with PLC-5 remote I\/O architectures and can connect to PLC-5 controllers through remote I\/O adapters such as the 1771-ASB, enabling distributed I\/O across a factory floor. It is not a standalone PLC processor; rather, it serves as the physical I\/O backbone within a PLC-5 system, hosting standard 1771 I\/O modules for input and output functions. Typical applications include expanding an existing PLC-5 control system with additional I\/O points distributed across multiple remote locations on a manufacturing, packaging, or process automation line, while maintaining centralized control and straightforward wiring through the 1771 backplane scheme.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"New","offer_id":46244003315946,"sku":null,"price":2893.0,"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-a2b-slc-500-plc-i-o-module","provider":"GTG Hardware","version":"1.0","type":"link"}
