Electrical isolation The different potential areas within a bus coupler are shown in the figures below.
Electrical isolation:
Incoming/outgoing remote
bus
The incoming and outgoing remote bus interface potentials are isolated from one
another and from the rest of the station electronics.
Electrical isolation:
FE/FE capacitive
FE and FE capacitive represent two individual isolated groups.
Electrical isolation: Other Other forms of electrical isolation depend on how the supply voltages are
provided.
1 The bus coupler supply U
BK
and the I/O supply U
M
/U
S
are supplied from
separate power supply units:
Fig. 4-2 Electrical isolation in the R-IBS IL 24 BK-T/U-PAC bus coupler
(separate power supply units)
Potential areas:
Fig. 4-2 to Fig. 4-4 show the electrical isolation in the bus coupler. The
internal wiring is not important here. It is shown in the terminal-specific
data sheet.
In Fig. 4-2 to Fig. 4-4 , the graphic symbols are not explained because
they are not important for indicating the electrical isolation. For an
explanation of the graphic symbols, please refer to the corresponding
data sheet or the DOK-CONTRL-ILSYSINS***-AW..-EN-P
application description.
