Frequently Asked Questions
What is USB isolation and why do I need it?
USB isolation galvanically separates the upstream and downstream USB circuits, preventing ground loops and electrical noise from damaging connected devices. The BB-UHR307's 4 kV isolation protects sensitive industrial equipment in environments with multiple power sources or high electromagnetic interference.
Is this 7-port USB hub suitable for hazardous locations?
Yes. The Advantech BB-UHR307 is UL Class 1 Division 2 certified, making it suitable for hazardous locations where flammable gases or vapors may be present under abnormal conditions. It meets rigorous industrial EMC standards for reliable operation in challenging environments.
What mounting options does the industrial USB hub support?
The BB-UHR307 features a versatile rugged metal enclosure that supports three mounting configurations: desktop placement, DIN rail mounting for control cabinets, and panel mounting for integrated system installations.
Does the USB 2.0 hub include a power supply?
The hub includes a 1.8 m USB cable but requires an external power source, which is sold separately. This allows flexibility in selecting appropriate power supplies for your specific industrial application.
