Notes 1) The supply terminal (UL) provides power for the module electronics and for the
consumers at the outputs. 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) To increase the maximum output current to up to 1 A, two outputs can be connected
in parallel.
