Configuration, Installation, and Startup of an Inline System (Example)
Information on the individual circuits in a Inline station can be found in
the DOK-CONTRL-ILSYSINS***-AW..-EN-P application description.
For additional information about the connection of the various supply
voltages, please refer to
Supplies".
The selection of suitable power supplies always depends on the individual system.
24 V DC power supplies should however always satisfy the following criteria:
Nominal value:
24 V DC
Ripple:
± 5%
Permissible range:
19.2 V to 30 V (ripple included)
If electrical isolation is required between logic and I/O, you must provide the bus
coupler supply U
and the I/O supply U
BK
If you want to set up various electrically isolated areas within an Inline station, you
must use additional power terminals that are supplied from separate power supply
units.
Logic and I/O are to be electrically isolated in an Inline station. They must therefore
be supplied from separate voltage sources.
The logic current consumption of the terminals is 337 mA corresponding to the
table
"Current consumption in the example project" on page
Two end clamps are needed to secure an Inline station on the DIN rail. Mount
these on both sides of the Inline station to keep it from moving from side to side.
Depending on the mounting position, Bosch Rexroth recommends SUB-M01-
ENDHALTER (MNR R911170685) end clamps for mounting on a horizontal DIN
rail; snapped on without tools or SUB-M01-ENDHALTER/AL (MNR R911171035)
end clamps for mounting on a vertical DIN rail; secured with screws.
Correct installation and assembly can minimize electromagnetic interference.
When installing an Inline station, please observe the grounding and shielding
measures described in the DOK-CONTRL-ILSYSINS***-AW..-EN-P application
description.
