{"product_id":"allen-bradley-1747-ke-interface-module","title":"Allen-Bradley 1747-KE Interface Module","description":"\u003cdiv\u003e\u003cp\u003eThe Allen-Bradley 1747-KE is a DH-485\/RS-232C Interface Module for the SLC 500 family that enables direct bridging between a DH-485 network and DF1-based devices, combining a DH-485 interface with an RS-232C serial path in a single module. It provides a DH-485 port and an RS-232C (DF1) interface for serial communications with PCs and DF1 peripherals, helping integrate AB automation components with legacy serial equipment. Power is drawn from the SLC backplane, requiring both 5 V DC and 24 V DC supplies; typical backplane current is about 150 mA at 5 V and 40 mA at 24 V. Key electrical specs include 500 V DC isolation and a built-in Real Time Clock rated at roughly ±1 minute per month at 25 °C (and ±6 minutes per month at 60 °C), supporting time-stamped data in communications. Common applications include connecting SLC 500 DH-485 networks to RS-232C\/DF1 devices, enabling PC programming and data exchange, and bridging legacy AB equipment to DF1 peripherals in manufacturing environments.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51658961879342,"sku":null,"price":43.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_b96dc5ed-0015-480e-8c9b-dd348fbd17f9.jpg?v=1769526027","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1747-ke-interface-module","provider":"PLG Automation ","version":"1.0","type":"link"}
