Total configuration with power supplies
Figure 5-4 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.
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 24VDC: Supply voltage with 24 V DC and infeed power to the backplane bus of
25 W
• PS 60W 24/48/60VDC: Supply voltage with 24/48/60 V DC and infeed power to the
backplane bus of 60 W
• PS 60W 24/48/60VDC HF:
– Supply voltage with 24/48/60 V DC and infeed power to the backplane bus of 60 W
– Extended retentive memory for CPUs as of FW V2.1.0 (see section Special requirements
• PS 60W 120/230V AC/DC: Supply voltage with 120/230 V AC and infeed power to the
backplane bus of 60 W
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 you can use a SITOP module, for example, as an
alternative.
• PM 70W 120/230VAC: Supply voltage with 120/230 V AC
• PM 190W 120/230VAC: Supply voltage with 120/230 V AC
