SCALANCE X414-3E power module

The power module is located in slot 2.
T he 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.
