Voltages, Currents
Current consumption from
S7-400 bus (5 VDC)
Typ. 1.8 A
Max. 2.0 A
Current consumption from
the S7-400 bus (24 VDC)
The CPU does not
consume any current at 24
V, and it only makes this
voltage available at the
MPI/DP interface.
Total current consumption
of the components
connected to the MPI/DP
interfaces, with a maximum
of 150 mA per interface
Backup current Typically 75 A
Maximum 860 A
Incoming supply of external
backup voltage to the CPU
5 VDC to 15 VDC
Power loss Typ. 9 W
CPU as DP Slave
You must not configure the CPU as DP slave.
