System Configurations
Expansion I/O Units
There are five types of Units available: Expansion I/O Units, an Analog I/O
Unit, Temperature Sensor Units, a CompoBus/S I/O Link Unit, and a Simple
Communications Unit.
CPU Unit
Expansion I/O Connector
(with cover)
A PC with 192 I/O points (the maximum) can be assembled by connecting five
Expansion I/O Units to a CPU Unit with 32 I/O points.
CPM2C-32CDTC-D
(16 inputs, 16 outputs)
Note Be sure that the power supply requirements of the CPU Unit, Expansion
Units, and Expansion I/O Units do not exceed the available capacity. Only
three Expansion I/O Units or Expansion Units can be connected when the NT-
AL001 Adapter is connected to the communications port (as a RS-232C port).
