The voltage U
S
supplies all of the devices connected to the segment circuit.
Electrical isolation
If electrical isolation is required between logic and I/O you must provide the field multiplexer
supply U
MUX
and the I/O supply U
M
/U
S
from separate power supplies.
4.1.2
Providing/supplying power at power and/or segment
terminals
In addition to supplying power for the I/Os on the field multiplexer you may also
provide/supply the voltages U
M
and/or U
S
with power and/or segment terminals.
4.1.3
Demands on the voltage supplies
The supply voltage to the sensors and actuators (U
M
/U
S
) should be installed and
protected independently of the field multiplexer supply (U
MUX
). In this way the bus
continues to run even if some I/O devices are switched off.
Please refer to the information in Section “Electrical isolation” on page 30 and in Section
“Connecting and configuring the field multiplexer” on page 53.
For detailed information on these terminals, please refer to the IL SYS INST UM E user
manual or the terminal-specific data sheets.
WARNUNG: Hazardous contact voltage
Only use power supplies that ensure safe isolation between the primary and secondary
circuits according to EN 50178.
For additional voltage supply requirements, please refer to the data sheets for the power
terminals.
