External I/O card D DI: 48 points, DO: 32 points A16B22020733
External I/O card E DI: 96 points, DO: 64 points A16B22020732
The I/O card contains a +24 V power input fuse, FU1, and +5 V power
output fuse, FU2. If +5 V is not output, fuse FU1 or FU2 may have blown.
In such a case, remove the fuses from their sockets, then check their
continuity using a multimeter (or visually check whether they have
blown). If a fuse has blown, investigate the cause, take appropriate action,
then replace the fuse. The capacity, part number, and location of the fuses
