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.
