Notes 1) The supply terminal (UL) provides power for the module electronics and for the
sensors at the inputs. The total current required for each module consists of the
sum of all partial currents.
2) Part of the XI/ON module’s electronics is supplied with module bus voltage (5 V DC),
the other part through the supply terminal (UL).
3) Max. permissible capacity: 141 nF at 79 V AC/50 Hz; 23 nF at 265 V AC/50 Hz
