Four Port rugged usB Hubs
UHR304 & UHR204
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.
