SeaI/O-463 50-Pin Header Connectors
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

Each of the four 50-pin connectors has the following pinout, which is compatible
with a wide variety of industry-standard solid-state relay racks:
