Example of wiring
1) In the case of sink wiring
When the main unit and a transistor output (sink) type input/output powered extension unit/block are used
2) In the case of source wiring
When the main unit and a transistor output (source) type input/output powered extension unit/block are
used

*1 To use the input terminal (X) of the input/output powered extension unit, wire the terminal as shown by the dotted line.
*2 The terminals in the shaded areas are provided on input/output powered extension units (ex.: FX
2N
-32ET).
Output extension blocks do
not have the terminals.
