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.      
Remember B&B Electronics when it comes to USB applications 
in harsh electrical environments.
