Alternate identifiers for this module include 549210 and AG-8256. By adding digital I\/O capacity to the existing controller, it supports more sensors, actuators, and status signals in a single installation without replacing the main processor, enabling scalability in discrete control applications. This expansion module is used within Apogee Automation 549 environments to extend the controller's digital I\/O capacity, helping to manage larger or more complex automation tasks across equipment and process lines that rely on Siemens 549 family hardware. Typical configurations combine this module with other 549-series digital expansion devices to tailor I\/O to specific machine layouts and control strategies.\u003c\/p\u003e\u003c\/div\u003e","brand":"Siemens","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46268238266602,"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-017.png?v=1788727429","url":"https:\/\/gtghardware.com\/products\/siemens-549-210-digital-point-expansion-module","provider":"GTG Hardware","version":"1.0","type":"link"}
