It delivers 2000 V of port-to-port isolation to protect equipment from surges and ground loops, supports RS-232 data rates up to 460.8 kbps (USB side operates at 12 Mbps), and employs a USB interface that can be powered from the USB bus (5 V) or from an external 10–30 VDC supply. The 2-port USO9ML2 variant typically consumes about 3 W, while the 4-port variant consumes around 5 W when an external supply is used. Its enclosure measures 6.5 × 1.2 × 3.1 inches without flanges (7.5 × 1.2 × 3.1 inches with flanges), and it is rated for operating temperatures from 0 to 70 °C with 0–95% non-condensing humidity. Regulatory approvals include FCC, CE, and UL, reflecting its suitability for industrial environments. The device remains compatible with USB 1.1 and 2.0 and preserves standard RS-232 signaling, making it a robust bridge between modern hosts and legacy serial equipment that requires isolated operation. \u003c\/p\u003e\u003c\/div\u003e","brand":"B\u0026B","offers":[{"title":"New","offer_id":51660451643694,"sku":null,"price":109.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_e2ff63fe-050f-4434-938f-f9eddfd71472.jpg?v=1769537759","url":"https:\/\/plgautomation.com\/products\/b-b-electronics-uso9ml2-usb-to-rs232-converter","provider":"PLG Automation ","version":"1.0","type":"link"}
