Description
The PB8H I/O mounting rack can accomodate up to eight
Opto 22 standard (Generation 1) digital single channel I/O modules
in any combination. The PB8H is designed to interface to Optomux
(B1), Pamux (B5), or Mistic (B100) protocol brain boards via a 50-pin
header connector. This 50-pin header connector also allows an
easy connection to computer parallel I/O ports via a 50-conductor
ribbon cable. Special mounting tabs allow the PB8H to be used
with the Opto 22 PBSA, PBSB, and PBSC power supplies.
