UHR304 USB Hub

The UHR304 from B+B SmartWorx is an industrial grade, four-port USB hub. It is designed and tested to meet heavy industrial EMC standards and is 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 3.4 lbs. force to disconnect them. The 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. The UHR304 is powered from an external 10 to 30 V_DC source. Two power connectors are provided - terminal block or threaded/lockable barrel plug. Each downstream port provides up to 500 mA of power to connected USB devices. Panel mount brackets and a DIN rail clip are included.
