Date: 04/11/2007

Product Highlights
  • Protects computers from damaging voltage spikes and surges
  • NEW SeaLATCH locking USB connectors prevent accidental cable disconnection
  • Provides power to USB peripherals
  • Rugged metal enclosure suitable for industrial environments

Sealevel Systems, Inc. announces the SeaI/O-270U, a seven-port optically isolated USB 1.1/2.0 compatible hub that protects computers from damaging power surges, spikes, and ground loops commonly found in industrial and OEM applications. The SeaI/O-270U offers system designers an effective tool for interfacing USB peripherals in virtually any environment. In addition to protection from electrical damage, the SeaI/O-270U includes Sealevel?s patent-pending SeaLATCHTM locking USB connector design to prevent accidental cable disconnection of both upstream and downstream USB ports.

The SeaI/O-270U provides up to 1500 VAC protection from harmful voltages injected on USB peripheral cabling. Status LEDs on the hub indicate external power, connection to the host, and fault conditions. The hub is housed in a rugged metal enclosure and each of the seven USB downstream connections provides a full 500mA of power suitable for all USB peripherals.

SeaI/O-270U hubs are supported in Windows, Linux, and all other operating systems that recognize USB. Simply provide power to the hub using the included power supply, plug the hub into an available USB port with the included cable, and the hub is automatically recognized.

Standard SeaI/O-270U hubs operate between 0?C to +70?C and designers can special-order extended temperature range (-40?C to +85?C) hubs. SeaI/O-270U hubs are available now and prices start at $379.
