The USB-104-IHUB is a small medical/industrial/military grade hub that features Tru-Iso signal isolation up to 4kV, extended temperature operation (-40°C to 85°C), high retention USB connectors, and an industrial steel enclosure for shock and vibration mitigation.

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.

This product utilizes a high-performance, low-power USB 2.0 hub controller. It is USB-IF certified, Windows Hardware Quality Lab (WHQL) compliant, and its operating temperature is rated for industrial grade environments. Being able to operate at industrial grade temperatures, the USB-104-IHUB offers its functionality to a wider range of user applications that many competitors' USB hubs can't provide.

Careful attention has been paid to isolation design, including extensive keep-out zones and hand-routed circuit paths, as well as component and material selection. Robust EFT, Lightning, and ESD protection at ±20kV on all signal pins (air and contact). See the Isolation specification in user manual for full details.

The card has LEDs that indicate its status. A green LED near the upstream portžs high-retention type B connector (visible through a cutout in the enclosure) indicates power to the upstream side. Each downstream port has two respective LEDs that provide status. A green LED near the downstream port's high-retention Type A receptacle (visible through a cutout in the enclosure) indicates that the port is enabled whereas the red LED indicates an overcurrent fault condition. The customer also has the option to specify jumper posts or a header connector to connect their own LEDs for panel mounting instead of the on-board LEDs if desired.

The USB-104-IHUB is fully protected from faulty peripherals connected to its downstream ports. Each port utilizes its own power distribution switch that provides overcurrent and short-circuit protection. If a fault occurs, the power distribution switch will disengage the respective port and enable its fault LED as a latched visual indicator to the user. A fault occurring on one downstream port will not affect other devices attached to the USB-104-IHUB other downstream ports. Any detected fault that occurs will result in a Windows message popping up on the monitor notifying the operator. To re-enable a faulted port, the user must clear the fault then cycle power to the hub.

The USB-104-IHUB needs bus power (from the USB upstream host port) and a medical grade external supply for isolated power.

The board is designed to be used in rugged industrial environments but is small enough to fit nicely onto any desk or testing station. The board itself is PC/104 sized (3.550" x 3.775", 90mm x 96mm) and ships inside a steel powder-coated enclosure with an anti-skid bottom. The enclosure is approximately 4" x 4" x 1".
