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.
