USB Digital I/O ‑ SeaDAC

Item #

Interface 32 optically isolated inputs via any USB

connection with the 8223. Inputs can range from 5‑30VDC

and provide 300V external isolation. Connection is made

using convenient 3.5mm removable screw terminal

connectors. To facilitate easy wiring, the inputs are grouped

in 4‑bit segments that each share a common.

SeaDAC modules are housed in a rugged, attractive plastic

enclosure and include a highly‑retentive USB Type B

connector to prevent accidental disconnection. The 8223 is

USB bus powered, so no external power supply is needed.

Standard operating temperature range of SeaDAC modules

is 0° C to 70° C and extended temperature range (‑40° C

to +85° C) is optional.

The SeaMAX software suite supports the SeaDAC family

and is designed to work with third party applications via

the SeaMAX API. Installation and operation is easy using

Windows 2000/XP and SeaMAX now supports the Windows

Vista operating system. Download the updated driver below.
