VersaPoint potential and data routing, and VersaPoint
connectors
3.1
VersaPoint potential and data routing
In order to operate the safety module it must be integrated in a VersaPoint station within
the VersaSafe or PROFIsafe system.
The bus signals are transmitted via the VersaPoint data jumpers. The required supply
voltages are transmitted via the VersaPoint potential jumpers.
The safety module interrupts the potential routing of the VersaPoint station for the segment
circuit.
3.2
Supply voltage U
L
Supply the 24 V supply voltage U
BK
/U
24V
at a bus coupler or a suitable power terminal.
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 VersaPoint potential jumper U
L
.
The supply voltage
U
L
is used to supply the communications power and the relays. For the
technical data for the supply voltage U
L
, please refer to Section "Supply voltage UL (logic,
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 VersaPoint sta-
tion, please refer to the GFK-2736 user manual.
If a new segment is to be opened in the VersaPoint station after the safety-related
segment circuit, the supply voltages U
M
and U
S
must be boosted at the power terminal
designed for the safety-related segment circuit.
WARNING: Loss of the safety function when using unsuitable power supplies
Please note for the voltage supply 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 Section "Electrical safety" on page 1-2.
