It provides two Fast Ethernet interfaces for hub expansion, with the Ethernet connection realized over fiber optic multimode cables terminated by duplex LC connectors. The module supports 62.5\/125 μm or 50\/125 μm multimode fiber and uses standard fiber links for hub interconnects. LED indicators monitor module status and bus function, while the unit draws about 2.3 W of power. The enclosure is IP20 rated, with operating conditions and installation notes specified in the X20 user documentation. Compatibility requires that the hardware revisions of the X20BC8083 and the X20HB8880 be at least F0 to operate with this revision. This hub expansion is intended for use in X20 hub networks to extend Ethernet reach across fiber links within industrial automation installations.\u003c\/p\u003e\u003c\/div\u003e","brand":"B\u0026R","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51660462326062,"sku":null,"price":87.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_b1bc4955-38fa-4c20-8502-f044857e808d.jpg?v=1769537859","url":"https:\/\/plgautomation.com\/products\/b-r-industrial-automation-x20hb2881-ethernet-hub-expansion-module","provider":"PLG Automation ","version":"1.0","type":"link"}
