Current consumption from the system power supply
Power consumption from input current path
Power consumption from output current path
Current demand of the connected sensors
Current demand of the connected actuators
The current demand is just under 10 A. The output current path must therefore be refreshed before the
11th module .
10 A is supplied by the EP-7641 module. The 1.81 A calculated as remaining after the 10th module must not be
added to the 10 A after the EP-7641 module!
