4.1
Inline Potential and Data Routing
In order to operate the safety module it must be integrated in a Rexroth Inline sta-
tion within the PROFIsafe system.
The bus signals are transmitted via the Inline data jumpers. The required supply
voltages are transmitted via the Inline potential jumpers.
The segment circuit is looped through the safety module and is available again
after the module. The segment circuit cannot be accessed in the safety module.

Supply Voltage U
L
Supply the 24 V supply voltage U
BK
/U
24V
at a bus coupler or a suitable power ter-
minal (R-IB IL 24 PWR IN/R-PAC). The 7.5 V voltage U
L
is generated from this
24 V supply voltage in the bus coupler or power terminal. It is supplied to the safety
module via the Inline potential jumper U
L
.
The supply voltage
U
L
is used to supply the communications power. For the tech-
nical data for supply voltage U
L
, please refer to
The maximum current carrying capacity for the supply voltage U
L
is 2 A.
This current carrying capacity can be reduced if certain terminals are used. Please
refer to the information in the terminal-specific data sheets.
For more detailed information about potential and data routing within
a Rexroth Inline station, please refer to the DOK-CONTRL-ILSYS-
INS***-AW..-EN-P application description.
Loss of the safety function when using unsuit-
able power supplies
Please note for the voltage supply at the bus coupler or power terminal that:
Only power supplies according to EN 50178/VDE 0160 (PELV) may be used.
Make sure that the output voltage of the power supply does not exceed 32 V even
in the event of an error.
Please also observe the points in
Chapter “Electrical Safety” on page 9
