Outline

Connect input/output extension blocks to the PLC to add more input/output points. 8 or 16 points can be
added by an input/output extension block.
Since the power is supplied from the main unit, it is not necessary to prepare another power supply unit for
each input/output extension block.

16.1.1 Product configuration

There are various types of input/output extension blocks. Select optimum blocks considering the input type,
output type, and connection unit of your system.
