{"product_id":"allen-bradley-1747-aic-isolated-link-coupler","title":"Allen-Bradley 1747-AIC Isolated Link Coupler","description":"\u003cdiv\u003e\u003cp\u003eThe Allen-Bradley 1747-AIC Isolated Link Coupler is a DH-485 network interface for the SLC 500 family that provides galvanic isolation between the DH-485 communications bus and the attached SLC 500 controller. It is used to connect SLC 500 devices to a DH-485 network, protecting both the controller and peripheral devices with up to 1500 V DC isolation between the communication cable and the SLC 500 processor. The coupler requires a 24 V DC power supply to power the unit and any connected DH-485 peripherals. Catalog number 1747-AIC, this module is designed for SLC 500 modular hardware configurations and serves as the isolated bridge on the DH-485 segment. Rockwell Automation discontinued the 1747-AIC as of January 31, 2017, so current availability is limited to remaining stock or used units. Common applications include linking SLC 500 CPUs (such as 5\/xx models) with DH-485 devices like HMIs or other DH-485 peripherals, enabling programming, monitoring, and data exchange while maintaining network isolation. This makes the 1747-AIC a legacy but historically important option for maintaining compatibility within older SLC 500 installations that rely on DH-485 communications.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"New","offer_id":51659707056430,"sku":null,"price":2331.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_b85d6170-98d9-4092-a152-d4201bef9b9d.jpg?v=1769529764","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1747-aic-isolated-link-coupler","provider":"PLG Automation ","version":"1.0","type":"link"}
