6.4 Front panel: Power supply (X101)
The connection to the power supply is implemented as a 2x2-pin housing plug (Phoenix Contact
P20THR-1818504). The main supply voltage (24 V) for the module is on PIN 3. This can also be
implemented as UPS-OCT (One Cable Technology), i.e. the signal for the UPS is also transmitted to the
board via this cable.
