{"product_id":"allen-bradley-1747-aic-analog-input-card-slc-500","title":"Allen-Bradley 1747-AIC Analog Input Card SLC 500","description":"\u003cdiv\u003e\u003cp\u003e1747-AIC is Allen-Bradley’s Isolated Link Coupler for the SLC 500 family. It’s not an analog input card; rather it serves as the DH-485 network gateway that connects an SLC 500 chassis to a DH-485 communication network, enabling remote devices and controllers to communicate on the same bus while electrically isolated from the backplane. The module installs in a 1747 backplane slot and uses a 6-position removable terminal block for DH-485 wiring. The isolation barrier protects the SLC 500 logic from noise and potential surges on the DH-485 network and is specified at 500 V DC. The 1747-AIC supports standard DH-485 traffic and is commonly used to link RSLogix 500 configurations with remote I\/O or multiple SLC controllers across a DH-485 network. In typical configurations, the AIC pairs with SLC-500 processors and other 1747 modules in a modular rack to extend network reach. This part is widely cataloged for legacy automation systems and is offered by authorized distributors with compatibility notes for revisions and DH-485 cabling. When selecting accessories for an SLC-500 DH-485 network, the 1747-AIC acts as the bridge at the rack boundary, ensuring data integrity across the bus and enabling reliable communication for controllers, HMIs, and remote I\/O networks.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51657304670510,"sku":null,"price":4350.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_3178b3ed-bc71-4d7e-8505-cabe4b404d2f.jpg?v=1769467727","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1747-aic-analog-input-card-slc-500","provider":"PLG Automation ","version":"1.0","type":"link"}
