Weight
Voltages, currents
Current consumption from S7–400 bus (5 V DC)
Current consumption from S7-400 bus (24 V DC)
The CPU does not consume any current at 24 V,
it only makes this voltage available on the
MPI/DP interface.
Current output to DP interface (5 V DC)
Backup current
Maximum backup time
Feed of external backup voltage to the CPU
Power loss
