The SeaI/O-463‟s 96 digital I/O channels are accessed via four industry-standard 50-pin header
connectors. Each header provides 24 bits of digital I/O divided into three eight-bit ports. Each
port may be individually configured via software command as an input or an output.
You will need to open the SeaI/O-463‟s enclosure to access the four header connectors: P2, P3,
P4, and P5. The connector designators are silk-screened onto the PCB for easy identification.

enclosure, attach the included strain-relief bracket to secure the cables and reassemble the
enclosure. Refer to the ribbon cable installation instructions included with the SeaI/O-463.

variety of industry-standard solid-state relay racks:
