BB-UHR304中文资料4-Port USB Full Speed Isolated Hub (USB cable included)数据手册Advantech规格书

描述 Description

The UHR304 is an industrial-grade, four-port isolated USB hub. It is designed and tested to meet heavy industrial EMC standards and is UL listed for Class1/Division2 hazardous locations allowing operation where standard office-grade hubs fail – such as near variable frequency drives, motor control centers, welding and other large electrical loads.4 kV isolation between the upstream and downstream USB ports protects expensive equipment from dangerous ground loops and helps ensure data integrity. High retention USB connectors hold standard USB cables tight and are perfect for high vibration applications - requiring up to 3.2 lbs-force to disconnect them. USB cable included.Powered from an external 10 to 30 VDC source. Two power connectors are provided – terminal block or threaded/lockable barrel plug. Each downstream port provides up to 500 mA of power to connected USB devices.
