{"product_id":"cincinnati-milacron-531-3312a-communication-module","title":"Cincinnati Milacron 531-3312A Communication Module","description":"\u003cdiv\u003e\u003cp\u003eThe Cincinnati Milacron 3-531-3312A Communication Module is a PCB-based PC communications board that serves as the dedicated interface within Cincinnati Milacron control systems. Also cataloged as 35313312A, this component is commonly described in vendor listings as a “communication module” or “communication board,” and is recognized by the identifiers 3-531-3312A, 531-3312A, and 35313312A. As a board-level module, it integrates into Milacron CNC\/control architectures to enable data exchange between the controller and external devices or subsystems, rather than acting as a separate processing or I\/O module. Verified listings explicitly label it a PC COMMUNICATION BOARD, underscoring its role as the communications interface in older Milacron equipment. Typical use cases involve replacement or repair of Milacron machines when a damaged or obsolete communication card interrupts the data link between the control system and peripheral equipment, with repair catalogs and aftermarket distributors repeatedly referencing the 3-531-3312A as a Cincinnati Milacron communications solution. The part’s long‑standing presence in Milacron repair literature and third‑party listings reflects its function as a dedicated communication interface within legacy Milacron control ecosystems.\u003c\/p\u003e\u003c\/div\u003e","brand":"Cincinnati","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51678075486510,"sku":null,"price":341.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_d46dd452-9ee9-4e69-81ac-0ed10fcf6213.jpg?v=1769571397","url":"https:\/\/plgautomation.com\/products\/cincinnati-milacron-531-3312a-communication-module","provider":"PLG Automation ","version":"1.0","type":"link"}
