S7-400, M7-400 Programmable Controllers Module Specifications

A5E00069467-07

The IF 961-AIO interface submodule receives its supply voltage from the M7-400
programmable modules or from the M7-300/400 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.
