Identified by part number 3-531-4531A, this slot card is also cataloged in some listings as 35314531A. Marketed as a Cincinnati Milacron HDCO board and described in repair and refurbishment catalogs, the card is positioned as an I\/O expansion module for Milacron’s HDCO PLC family. As a discrete PCB-based I\/O slot card, it provides sixteen individual I\/O points to extend the controller’s footprint without replacing the main CPU module. This makes it suitable for retrofitting or upgrading existing Milacron HDCO installations that require additional I\/O channels. Various suppliers list this part under the Milacron HDCO board lineage and note its role as a replaceable, serviceable component within the HDCO ecosystem, reflecting its status as an active option for maintenance and inventory management of Milacron control systems.\u003c\/p\u003e\u003c\/div\u003e","brand":"Cincinnati","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51678078959918,"sku":null,"price":362.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_8b7fa5f4-38fa-4416-a9d6-bab3fb4d0674.jpg?v=1769571442","url":"https:\/\/plgautomation.com\/products\/cincinnati-milacron-3-531-4531a-hdco-plc-slot-card","provider":"PLG Automation ","version":"1.0","type":"link"}
