Setup with different voltage classes
When setting up expansion modules of different power volt-
ages, take the following restrictions into consideration.
Note
•
To power the CPU module and expansion I/O modules,
use one power supply to supply the same power voltage.
When using different power supplies, the fast transient/
burst immunity (IEC61000-4-4) will be 1 kV (power sup-
ply).
•
A 100 to 240V AC/DC module cannot be connected to the
right side of a 12/24V DC, 24V DC, or 24V AC/DC mod-
ule.
•
For analog input module and AS-Interface communica-
tion module, a module of any voltage can be connected
to the left side. To the right side, however, a 100 to 240V
AC/DC module cannot be connected.
