Bosch Rexroth IndraControl L10 - +24 V Supply of Segment Circuit US

Several independent segments can be created within the main circuit. The main
circuit provides the
voltage potential, from which the segment voltages (U
S
) are
derived. The splitting into segments permits to protect or switch e. g. the supply
of several actuators separately.
The maximum current carrying capacity is 8 A. When the limit value is reached,
a new power terminal has to be used.

In the simplest case, the main voltage U
M
can be supplied at the
IndraControl L10.
M
can also be supplied via a power terminal. A power terminal must be used in
the following cases:
1. An electrical isolation is to be set up.
2. The maximum current carrying capacity of a voltage jumper

, total
current of U
S
and U
M
(GND)) is reached.
+24 V Supply of Segment Circuit US
The
segment circuit
supply U
S
is to be connected to terminal 1.1 and is supplied
through the following series Rexroth Inline I/O modules by the lateral contacts
(voltage jumper). It forms the segment circuit or auxiliary circuit of the Rexroth
Inline modules and the onboard I/Os.
The segment circuit with the segment voltage U
S
starts at the
IndraControl L10 or a supply terminal (power terminal or segment terminal) and
is supplied through all following modules up to the next supply terminal.
From U
S
the initiator supply as well as the signal voltage of the outputs is pro‐
vided. Several segment terminals can be used within a main circuit and can
thereby segment the main circuit. The reference to ground is the same as that
of the main circuit. Thus, different fused electric circuits can be implemented
within the station without any external cross wiring.
The voltage in the segment circuit is 24 V DC.
The maximum current carrying capacity is 8 A. When the limit value is reached
for
a
voltage
jumper U
M
(U
M
, U
S
or the total current of U
S
and U
M
(GND)), a new
power terminal has to be used.
The segment voltage U
S
can be provided in various ways:
