Installed in the CPU slot of each expansion base, it communicates with the DL205 CPU to manage expanded I\/O resources. Each D2-CM includes a rotary switch to assign a unique expansion-base number that the CPU recognizes, enabling up to four expansion bases to be connected to one DL205 system. This module is part of AutomationDirect's Expansion I\/O family and is intended specifically for use with DL205 CPUs when additional local I\/O capacity is required without replacing the main controller. By distributing I\/O across dedicated expansion bases, designers can tailor wiring and topology to fit space and control needs while maintaining centralized program and data access from the main DL205 CPU.\u003c\/p\u003e\u003c\/div\u003e","brand":"AUTOMATION","offers":[{"title":"New","offer_id":46274532016362,"sku":null,"price":86.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-075.png?v=1788727429","url":"https:\/\/gtghardware.com\/products\/automationdirect-d2-cm-expansion-controller-module","provider":"GTG Hardware","version":"1.0","type":"link"}
