3.4.2.1 SCALANCE X414-3E power module
The power module is located in slot 2.
The power module can be supplied with power redundantly over two inputs. The two power
inputs are isolated from each other, there is no power distribution. If redundant power feed-in
is used, the switch is supplied solely by the section of the power module with the higher
output voltage.
The front 4-pin connector is used for the power supply. The input voltage is 24 V DC (20.4 –
28.8 V). The signaling contact supplies the fault status at the rear 4-pin connector. If there is
a fault, the contact opens.
