Notes
1)
The supply terminal (U
L
)
provides power for the module electronics and for the analog transmitters 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 (U
L
).
