13.8.3 Technical Specifications
Technical Specifications

The IF 961-CT1 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.
