It uses two DB9 male (DTE) RS-232 ports and a USB Type-B female connector, and is built around an FT232RL USB-to-serial controller for reliable USB connectivity. The unit provides port-to-port isolation up to 2000 V with optical isolation and 15 kV ESD protection, making it suitable for demanding industrial environments. USB supports 1.1\/2.0 with data rates up to 12 Mbps, while RS-232 channels operate up to 460.8 kbps to handle typical automation and data-logging tasks. Power can be drawn from the USB bus or an external 10–30 V DC supply; power consumption is listed as about 3 W for the 2-port model and 5 W for the 4-port variant. Dimensions are 16.4 cm x 3.0 cm x 8.0 cm (without flanges) and 19.0 cm x 3.0 cm x 8.0 cm (with flanges), with a weight around 0.73 lb for the 2-port and 0.77 lb for the 4-port version. Operating temperature ranges from 0 to 70 °C, storage from -40 to 85 °C, and humidity tolerance is 0–95% non-condensing. Regulatory approvals include FCC, CE, and UL. Driver support is available for Windows platforms (including 32- and 64-bit) across multiple generations, with separate 32\/64-bit installers for 64-bit Windows as well as older 32-bit packages. Note: this product line is discontinued by many distributors, now listed as obsolete in several catalogs. Common uses include bridging USB-enabled hosts to legacy PLCs, data loggers, and other RS-232 devices in industrial automation. The USO9ML2DR-2 is also sold as BB-USO9ML2-2P, reflecting the same 2-port USB-to-serial functionality. \u003c\/p\u003e\u003c\/div\u003e","brand":"ADVANTECH","offers":[{"title":"New","offer_id":51657038135598,"sku":null,"price":363.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_f8cf4456-b5ba-48a2-b030-d558a8e3bdb6.jpg?v=1769465434","url":"https:\/\/plgautomation.com\/products\/advantech-uso9ml2dr-2-programmable-logic-controller-module","provider":"PLG Automation ","version":"1.0","type":"link"}
