It supports up to 31 nodes per segment and baud rates up to 12 Mbit\/s, enabling reliable communication across distant devices in a single PROFIBUS\/MPI installation. The standard RS485 repeater (0AA01-0XA0) occupies one bus node, operates from a 24 V DC supply, and features an IP20 enclosure for indoor industrial mounting, making it suitable for control panels and DIN-rail installations. Intended to bridge PROFIBUS\/MPI segments rather than diagnose network conditions, this model is used in automation cells, machine lines, and factory floors where network reach or node count must be extended; Siemens also offers a diagnostic variant 6ES7 972-0AB01-0XA0 for different installation needs. \u003c\/p\u003e\u003c\/div\u003e","brand":"Siemens","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46268526002410,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-018.png?v=1788727429","url":"https:\/\/gtghardware.com\/products\/siemens-ag-6es7-972-0aa01-0xa0-rs485-repeater","provider":"GTG Hardware","version":"1.0","type":"link"}
