Principais características



Our Industrial Grade USB Hubs are designed for the harshest environments. They are EMC tested to meet heavy industrial standards. The four port hubs 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. The UHR304 and UHR307 offer 4 kV Isolation between the upstream and downstream USB ports to protect expensive equipment from dangerous ground loops and to help ensure data integrity. No doubt about it, these hubs will operate where standard office grade hubs fail – such as near variable frequency drives, motor control centers, welding, and other large electrical loads.


Isolation: 4 kV on models UHR204 and UHR304

Wide Operating Temperature: (-) 40 to (+) 80C

ESD Protection: 15 kV

Shock, Drop, and Vibration Tested

Rugged metal panel mount housing


When deciding between the isolated models and the non-isolated models, you should be aware that isolation technology available on the market today is limited to 12 Mbps. USB 2.0 devices operate at one of three speeds. Low speed devices, such as a keyboard or mouse, operate at 1.5 Mbps (USB 1.1). This is called “Low Speed.” Other devices, such as scanners or printers may operate at 12 Mbps (USB 1.1). This is called “Full Speed.” Devices such as USB video cameras may require 480 Mbps (USB 2.0). This is called “High Speed” USB. Our USB Hubs support 2.0 – However, the isolated hubs do not support “High Speed” 480 Mbps and will ratchet back to 12 Mbps.


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
