Examples of wiring
In the case of sink wiring
When the main unit and a transistor output (sink) type input/output powered extension unit/block are used
0.1A 50V
diode is
necessary.
S/S 0V
*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
Output extension blocks do not have the terminals.
