SeaI/O User Manual
462 Series – 96 Channel TTL DB-78
Perfect for driving industry-standard solid-state relay (SSR) racks, the SeaI/O-462
provides 96 bits of buffered drive TTL I/O. Each DB-78 connector brings out 48 I/O
bits addressable as six, eight-bit ports. For easy connection to relay racks, Sealevel
offers a six-foot cable (Item# CA237) that terminates each DB-78 connector to two
industry standard 50-pin IDC connectors. Order part number 462x-KT and receive
two CA237 cables with each unit.
