The unit provides an RS-232 host interface on the PC side and a DH-485\/RS-485 peripheral link on the network side, enabling direct serial communication with DH-485-equipped devices such as SLC-500 CPUs and PanelView 600 HMIs. In catalog and installation literature, the 1747-PIC (also listed as 1747-PIC\/A in some catalogs) is described as the RS-232-to-RS-485 interface converter for SLC-500 systems, and it is referenced within Rockwell manuals as a standard peripheral interface option for connecting serial equipment to a DH-485 network. Common use cases include configuring, monitoring, or exchanging data with SLC-500 controllers via a PC’s serial port or integrating PanelView 600 terminals that rely on DH-485 communications through this converter. The product is discussed in multiple Rockwell documentation sets and third-party listings as a dedicated RS-232–to–DH\/RS-485 bridge for the SLC-500 family, with notes on compatibility considerations and legacy software workflows.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51658956210478,"sku":null,"price":51.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_8d7fb4dd-dbce-414b-9caf-5aa00a629a40.jpg?v=1769525938","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1747-pic-peripheral-interface-card","provider":"PLG Automation ","version":"1.0","type":"link"}
