Technical Specifications
The IF 964-DP interface submodule receives its supply voltage in the S7-400 from
the central processing unit and in the M7-400 from the programmable modules or
from the expansion modules. The current consumption given in the technical
specifications is the consumption required for dimensioning the power supply, that
is, the current consumption is referenced to 24 V in the M7-300 and to 5 V in the
M7-400.
