Figure 3-4
Total configuration with load current supply (PM) and system power supply (PS)
Optionally, you can insert up to two system power supplies (PS) in the slots to the right of the
CPU/interface module (power segments).
The number of load current supplies is unlimited.
Observe the installation rules and specified installation distances in the manuals of the load
current supplies.
System power supplies
● PS 25W 24V DC: Supply with 24 V DC and 25 W of power
● PS 60W 24/48/60V DC: Supply with 24/48/60 V DC and 60 W of power
● PS 60W 120/230V AC/DC: Supply with 120/230 V AC and 60 W of power
Load current supplies
The load current supplies listed below have been technically adapted especially to the
S7-1500 automation system/ET 200MP distributed I/O system. Use of the listed load current
supplies is not imperative because a SITOP module, for example, can be used an
alternative.
● PM 70W 120/230 V AC: Supply with 120/230 V AC and 70 W of power
● PM 190W 120/230 V AC: Supply with 120/230 V AC and 190 W of power
