Supply Voltage U
M
Supply the supply voltage at a bus coupler or a power terminal. It is supplied to the
safety module via the Inline potential jumper U
M
.
The supply voltage
U
M
is used to supply the output circuits. For the technical data
for supply voltage U
M
, please refer to
The maximum current carrying capacity for the main circuit U
M
is 8 A (total current
with the segment circuit that is not used in the safety terminal). This current carry-
ing capacity can be reduced if certain terminals are used. Please refer to the infor-
mation in the terminal-specific data sheets.
If the limit value of the potential jumpers U
M
and U
S
is reached (total current of U
S
and U
M
), a new power terminal must be used.
For the behavior of the safety module in the event of an error at the supply voltage,
please refer to
Chapter “Supply Voltage Errors” on page 58

Loss of the safety function when using unsuit-
able power supplies
Please observe the points in
Chapter “Electrical Safety” on page 9
Module damage due to polarity reversal
Polarity reversal places a burden on the electronics and, despite protection
against polarity reversal, can damage the module. Therefore, polarity reversal
must be prevented.

ages
Supply the supply voltages U
M
and U
S
at a bus coupler and/or a power terminal
from the same power supply unit, so that the loads of R-IB IL 24 PSDO 8-PAC are
not affected by parasitic voltages in the event of an error.
