Introduction The SeaI/O-270U is an optically isolated 7-port USB hub that protects the host computer from spikes, surges and ground loops commonly found in industrial environments. The hub is powered by an industrial grade wall-mount power supply providing a full 500mA to each attached USB peripheral. The SeaI/O-270U is ideal for adding USB ports to a SeaPAC touchscreen HMI system, a Relio R1000 embedded solid-state industrial computer, or a SeaI/O data acquisition “stack”.

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.
Status LEDs Status LEDs are also included on the front of the SeaI/O-270U module to indicate the following information: ENABLE (Yellow) – Lights when the USB hub is enumerated by the host system. FAULT (Red) – Lights when there is a problem with a downstream USB port. Disconnect the downstream devices one at a time until the status returns to normal. EXT POWER (Green) – Indicates the external power supply is properly connected to the hub and an AC power source.
SeaLATCH™ USB The SeaI/O-270 integrates patent-pending SeaLATCH USB ports, which are fully compatible with standard USB cables. When used with the included USB cable (Item# CA356) with a SeaLATCH USB type B connector, the metal thumbscrew provides a secure metal-to-metal connection to the hub and prevents accidental cable disconnection. The hub’s seven SeaLATCH type A USB connectors can secure USB peripherals to the hub in the same way.
SeaLATCH Locking USB Cables SeaLATCH USB Connectors SeaLATCH locking USB cables integrate a small thumbscrew into each USB connector.
