It provides a bridge between a personal computer’s RS-232 serial port and the SLC 500 DH-485 network, enabling programming, monitoring, and data exchange with SLC 5\/01, 5\/02, and 5\/03 processors.\u003c\/p\u003e\n\u003cp\u003eOn the PC side, the 1747-PIC uses RS-232 signaling, handling TXD, RXD, RTS, and DTR with a ground reference. A 9-pin to 25-pin adapter is used to match the host serial port, and the unit can draw power from the DH-485 link via the controller—no separate power supply is required. On the SLC 500 side, it presents a DH-485–compatible RS-485 interface for half‑duplex communication on the PLC network. Typical installations reference Rockwell cables for PC-to-PLC connections, including options such as 1747-C13 or 1747-CP3 to link the processor’s channel to the PC.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51658956243246,"sku":null,"price":116.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_c35c2732-4a41-4a00-aaa6-6660ed306a42.jpg?v=1769525939","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1747-pic-pc-interface-converter","provider":"PLG Automation ","version":"1.0","type":"link"}
