It provides eight shielded RJ45 ports supporting 10BASE-T\/100BASE-TX with autonegotiation and automatic MDIX, delivering up to 100 Mbps per port and a hub propagation delay of 0.64–0.68 µs. On the front, per-port LEDs show network activity (RX, orange) and per-port link\/collision status (Link = green, Collision = red), plus a supply-voltage indicator to confirm operation. Half-duplex operation is supported while full-duplex is not. The device is designed for industrial control equipment and can function as a Level-2 hub in standard Ethernet topologies, interconnecting sensors, controllers, and other field devices within a single subnet. The 0AC808.9-1 requires a TB704-series terminal block (sold separately) to provide 24 VDC power; compatible options include TB704.91 (4-pin push-in) and TB704.9 (4-pin screw clamp). Certifications include CE and UL\/cULus for industrial use. The unit uses shielded RJ45 cabling and supports a maximum segment length of 100 meters between stations. This hub is part of B\u0026amp;R’s 0AC infrastructure components and is built for reliable, stand-alone operation in automation environments.\u003c\/p\u003e\u003c\/div\u003e","brand":"B\u0026R","offers":[{"title":"New","offer_id":51660473893166,"sku":null,"price":580.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_1bf1a3af-7d7b-40a7-b612-5fe8bbe4fde2.jpg?v=1769538011","url":"https:\/\/plgautomation.com\/products\/b-r-industrial-automation-0ac808-9-1-ethernet-hub","provider":"PLG Automation ","version":"1.0","type":"link"}
