It provides a reliable shielded twisted-pair communication interface for the Data Highway 485 (DH-485) network, enabling secure and stable data exchange between controllers, operator interfaces, and programming devices. This model requires a nominal 24 VDC external power supply source with a current load of 0.085 A.\u003c\/p\u003e\n\u003ch3\u003eNetwork Isolation and Interface\u003c\/h3\u003e\n\u003cp\u003eThe unit acts as a physical communication junction that protects sensitive controller ports from electrical noise, voltage transients, and ground loops commonly found in industrial plant floors. It features multi-port connectivity, allowing simultaneous access for network trunk lines, CPU connections, and handheld or PC-based programming terminals.\u003c\/p\u003e\n\u003ch3\u003ePower Requirements and Wiring\u003c\/h3\u003e\n\u003cp\u003ePowered externally via a 24 VDC source, the module maintains a low operational current draw of 0.085 A. Wiring to the DH-485 network utilizes standard shielded twisted-pair cabling, such as Belden 3106A or 9842, to ensure signal integrity over extended factory automation network distances.\u003c\/p\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003e1747-AICR\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eAllen-Bradley\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eIsolated Link Coupler\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSeries\u003c\/td\u003e\n\u003ctd\u003eSLC 500\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommunication Interface\u003c\/td\u003e\n\u003ctd\u003eShielded Twisted-Pair (DH-485)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eExternal Power Supply\u003c\/td\u003e\n\u003ctd\u003e24 VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCurrent Load\u003c\/td\u003e\n\u003ctd\u003e0.085 A @ 24 VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.29 lbs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003cp\u003eFrequently Asked Questions\u003c\/p\u003e\n\u003cp\u003eQ: What is the primary function of the 1747-AICR in an industrial control network?A: It serves as an isolated link coupler to connect SLC 500 controllers and peripheral devices to a DH-485 network while providing electrical isolation to safeguard communication ports.\u003c\/p\u003e\n\u003cp\u003eQ: Does this module require an external power supply for operation?A: Yes, it requires an external 24 VDC power source with a current load capacity of at least 0.085 A when linked to devices that do not supply power through the communication port.\u003c\/p\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":53256166244632,"sku":"1747-AICR","price":270.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0892\/3483\/3688\/files\/1747-PCIL2_Cocoai.jpg?v=1794451090","url":"https:\/\/www.innoplcsync.com\/products\/allen-bradley-1747-aicr-isolated-link-coupler","provider":"InnoPLC Sync Co., Ltd.","version":"1.0","type":"link"}
