The unit offers 3000 VDC isolation specifically on the RS-232 side, allowing the RS-485 network to be grounded or powered independently from the host equipment; it draws power from a 10–30 VDC supply with a maximum consumption of 2.2 W, making it compatible with many industrial power sources. The RS-232 interface uses a female 9-pin D connector, and the device includes an automatic self-tuner to simplify setup and ensure stable RS-485 communication in varying network conditions. This model is listed as discontinued by the manufacturer, so buyers should confirm current compatibility, supplier support, and whether newer CB-Com or compatible conversion options exist for new designs. For practitioners integrating legacy equipment, the CB-7520 provides a straightforward path to add RS-485 capability while maintaining isolation on the host side.\u003c\/p\u003e\u003c\/div\u003e","brand":"CB-Com","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51677879599406,"sku":null,"price":435.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_90889ba8-4bc1-4672-a43d-9fd4def593c8.jpg?v=1769568863","url":"https:\/\/plgautomation.com\/products\/cb-com-cb-7520-isolated-rs-232-to-rs-485-converter","provider":"PLG Automation ","version":"1.0","type":"link"}
