USB hub features 4kV isolation & extended temperature operation

The USB-104-IHUB now makes it easy to expand the number of USB ports and provide up to 4kV isolation between the host computer and connected USB peripherals. Applications include factory automation, hospital and medical, energy management, military/mission-critical, transportation, security systems, and process monitoring.

Designed to integrate well in any application, the unit is available in a rugged steel enclosure or OEM as a "board-only" 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. Available accessories include an isolated medical-grade power supply and a wide variety of standard USB cables for quick and easy-to-use, out of the box, connectivity. To make use of the miniature embedded USB header connectors, ACCES offers an assortment of embedded micro-fit USB header cables.

The USB-104-IHUB is especially useful in applications where high common-mode external voltages are present. Isolation is required to guard electronics from transient voltage spikes and offers greater common-mode noise rejection in electrically noisy surroundings containing industrial machinery and inductive loads. In addition to protecting applications from the influence of high external voltages, isolation eliminates troublesome ground loops.
