2-2-8 High-density I/O Units Classified as Special I/O Units
Some High-density I/O Units are classified as Special I/O Units. Up to 10 or up to
16 Special I/O Units can be connected to a PC depending on the CPU Unit that is
used. These Units have two 24-pin connectors. In general, these Units control
32 I/O points, although some Units can control 128 I/O points when set for
dynamic operation.
Refer to Appendix B Specifications for detailed specifications and dimensions of
the Units.
