The USB-104-IHUB from ACCESI/O is a small form factor 4 port USB hub featuring Tru-Iso™ signal isolation up to 4kV. The hub has extended temperature operation (-40°C to 85°C), high retention USB connectors, and an industrial steel enclosure for shock and vibration mitigation, making it perfect for military, medical and industrial applications.

The USB-104-IHUB utilises a high-performance, low-power USB 2.0 hub controller that is USB-IF certified and Windows Hardware Quality Lab (WHQL) compliant. It's especially useful in applications where high common-mode external voltages are present as isolation is required to guard electronics from transients and to eliminate troublesome ground loops. The unit also offers greater common-mode noise rejection in electrically noisy surroundings containing industrial machinery and inductive loads. 

Available in a rugged steel enclosure or as an OEM bare board device, users may choose from two power input connectors: a DC power input jack or screw terminals to provide a full 500mA source at 5V on each of the downstream ports. Additionally, a wide input power option exists to accept from 7VDC to 35VDC. Mounting provisions include DIN rail and various panel mounting plates.
