8 NA300 System Configuration

□ Synopsis
NA300 intelligent programmable controller provides flexible system configuration,
in which I/O module includes local I/O and remote I/O. Because different types of
NA300 PLC modules can be fixed in any position of the backplane, flexibility of system
configuration is greatly improved. To build a NA300 system, CPU module, I/O modules,
backplane, wiring cable and relay accessories need to be selected. This chapter will
introduce how to choose them.

8.1 How to choose I/O modules

Before system configuration, you may calculate the number of I/O points according
to the practical application at first. Final number of I/O points is the number you
calculated multiplied by 1.1-1.2. This may facilitate expansion.
