13.9.3 Technical Specifications
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.
