Current load capacity
Ensure you comply with the current load capacity of the module and periphery supply (see
"Technical Details"). If the current load is higher, an additional supply voltage module is re-
quired to refresh the module supply and periphery supply.
}
Module supply
The current load is the total current consumption of all the electronic and compact mod-
ules.
The module supply does not automatically switch off if values exceed or drop below
their limits. However, the "5 V" LED will light and a message will be entered in the error
stack or diagnostic log.
}
Periphery supply
The current load is the total current consumption of the sensors, actuators and test
pulses supplied via the input/output modules.
The periphery supply does not automatically switch off if values exceed or drop below
their limits. However, the "24 V" LED will light and a message will be entered in the er-
ror stack or diagnostic log.
Please refer to the derating diagram.
}
C-rail
If the current load is higher, the C-rail must use a different supply to prevent overload.
Please refer to the derating diagram.
