1.6 Functionality
1.6.1 Power Supply
There is a power connector for powering the processor unit.
Terminal X6 (label: V+/0V) features a 24-V connector for the processor unit
and all the slice modules connected to the system bus.
If there is a voltage dip of the 24 V supply voltage (switching threshold is
about 10 V) then a power-down logic switches of the 5 V supply to the signal
modules (central I/O).
1.6.2 Local inputs/outputs
The digital inputs/outputs can be used either as an input or as an output and
connected to sensors or actuators.
They can be used for an interrupt circuit in the application.
When used as outputs, they are designed for 24-V signals.
The following applies to XC-303-…: The digital inputs/outputs feature an addi-
tional separate, shared power supply at X2 (label: UL/–) that is galvanically
isolated from the bus.
The following applies to XC-204-: The digital inputs/outputs use the shared
power supply at X4 (label: V+/0V), which is not galvanically isolated from the
bus.
The outputs can be loaded with 500 mA, a duty factor (ED) of 100% and a
utilization factor (g) of 100%.
The outputs are short-circuit proof.
