The UHR304 and UHR204 are Industrial Grade Four Port USB Hubs. They are designed and tested to meet heavy industrial EMC standards and are UL listed for Class 1 Division 2 hazardous locations. 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. Model UHR304 has 4 kV Isolation between the upstream and downstream USB ports to protect expensive equipment from dangerous ground loops and to help ensure data integrity.

The Heavy Industrial EMC specifications allow these hubs to operate where standard office grade hubs fail – such as near variable frequency drives, motor control centers, welding, and other large electrical loads.

They are powered from an external 10 to 30 VDC source. The non-isolated UHR204 may also be powered from the USB bus. Two power connectors are provided - terminal block or threaded / lockable barrel plug. Refer to ordering information for power supply recommendation. Each downstream port provides up to 500 mA of power to connected USB devices. Refer to the specification table for additional information concerning downstream power. Panel Mount Brackets and a DIN Rail Clip are included.

  • Operating Temperature: (-)40 to (+)80 C
  • Speed (isolated versions): 12 Mbps or 1.5 Mbps
  • Speed (non-isolated versions): 480 Mbps, 12 Mbps, or 1.5 Mbps
  • Isolation (UHR304 & UHR307): 4 kV
  • ESD Protection: 15 kV
  • Power: Bus powered (UHR204 – see restrictions) or External 10 to 30 VDC
