It provides a DH-485 network interface and a DF1 RS-232C port that can be configured for RS-232\/423, RS-422, or RS-485 devices, enabling DF1 communications over a DH-485 network. The module is powered from the SLC backplane, requiring both 5 V DC and 24 V DC supplies, with backplane currents around 150 mA at 5 V and 40 mA at 24 V. It includes 500 V DC isolation between the backplane and the serial side and features a built-in Real Time Clock rated for about ±1 minute per month at 25 °C (with drift of +0\/−6 minutes per month at 60 °C). Typical applications include connecting a DH-485 field network to a DF1-based device such as a PC or HMI, enabling reliable data exchange between DH-485 and DF1-equipped equipment in legacy AB installations.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51659706106158,"sku":null,"price":3110.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_8091466d-5c04-465c-b664-83441a14fcfc.jpg?v=1769529759","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1747-ke-dh-485-rs-232c-communications-interface","provider":"PLG Automation ","version":"1.0","type":"link"}
