Hardware Description
Optical Isolation
The SeaI/O-270U is an optically isolated
USB hub that connects up to seven USB
peripherals while protecting the host
computer from voltages up to 1500 VAC.
This protects the host computer from potentially damaging voltage spikes, power
surges, and ground loops commonly found in industrial and OEM applications.
USB Ports
The SeaI/O-270U integrates patent-pending SeaLATCH USB ports, which are fully
compatible with standard USB cables. When used with the included USB cable
with a SeaLATCH type B USB connector, the metal thumbscrew provides a secure
metal-to-metal connection to the hub and prevents accidental cable disconnection.
Additionally, a highly-retentive type B USB connector helps prevent unintentional
separation from a standard USB cable. The SeaLATCH type B locking connector
and high retention type B port are shown below.
The hub’s seven SeaLATCH type A locking USB connectors can secure USB
peripherals to the hub in the same way. Two of the SeaLATCH type A USB ports
are shown below. Each of the seven downstream type A USB ports provides a full
500mA to USB peripherals.
