Bosch Rexroth IndraControl L40 - Internal Voltages

7-6 Connections and Interfaces IndraControl L40
DOK-CONTRL-IC*L40*****-PR02-EN-P
Note: Voltages U
M
and U
S
are electrically isolated from U
L
.
Requirement: Power supply units that are electrically isolated
from the power supply unit for U
LS
are used for voltages U
M
and U
S
.
Note: When designing the station, please note that the total current
in the segment circuit U
S
and the main circuit U
M
must not
exceed 8 A.
Note: U
M
is interrupted by the terminal PWR IN.
U
S
is interrupted by the terminals PWR/IN and SEG/F.
Internal Voltages
+7.5-V Inline Supply U
L
The +7.5-V Inline supply voltage U
L
is generated from the supply voltage
U
LS
inside the IndraControl L40 and is supplied through all connected
Rexroth Inline I/O modules. It is the logic voltage supply (via voltage
jumpers) of the Rexroth Inline modules.
This logic circuit starts at the IndraControl L40 and is supplied through all
modules of a station.
Logic voltage is supplied from the Inline supply to all modules of the
station.
The voltage in this circuit is 7.5 V.
The Inline supply is generated from the supply voltage U
LS
of the
IndraControl L40.
The maximum current carrying capacity of the Inline supply is 2 A.
+24-V Analog Supply (UANA)
The 24-V analog supply is also generated from the voltage U
LS
. It starts in
the IndraControl L40 and is supplied through all Rexroth Inline I/O
modules. It is the voltage supply (via voltage jumpers) U
ANA
of the Rexroth
Inline analog modules.
The peripheral equipment of the modules for analog signals is supplied
from the analog circuit.
The voltage in this circuit is 24 V.
The analog voltage U
ANA
is generated from the logic voltage U
LS
of the
IndraControl L40.
The maximum current carrying capacity of U
ANA
is 0.5 A.
