24 V Supply Voltage of the Main Circuit U
M
The 24 V voltage for the main circuit supply U
M
on terminal 2.2 is not used for
IndraControl L45/L65/L85.
A main circuit U
M
begins at a power terminal at the IndraControl L45/L65/L85
and is lead to the next power terminal through all following terminals. At the
next power terminal, a new circuit is started; its potential is isolated from the
previous one.
Several power terminals can be used within one station.
Function Several segments, independent from each other, 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 pro‐
tect or switch e. g. the supply of several actuators separately.
Current carrying capacity The maximum current carrying capacity is 8 A (total current with the segment
circuit). If the limit value has been reached, a new power terminal must be used.

Generation of U
M
In the simplest case, the main voltage U
M
can be supplied at the IndraCon‐
trol L45/L65/L85.
U
M
can also be supplied via a power terminal. A power terminal is to 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 (
M
, U
S
or GND,
total current of U
S
and U
M
) is reached.
+24 V Voltage of Segment Circuit U
S
Connect the segment circuit U
S
to contact 1.1. The segment circuit supply U
S
is supplied through the following series Rexroth Inline I/O terminals. It forms the
segment circuit or auxiliary circuit (via voltage jumpers) of the Rexroth Inline
terminals and the onboard I/Os.
The segment circuit with the segment voltage U
S
starts at the IndraControl L45/
L65/L85 or a supply terminal (power terminal or segment terminal) and is sup‐
plied through all following terminals up to the next supply terminal.
Function Several segment terminals within a main circuit can be used and thereby seg‐
ment 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 sta‐
tion without any external cross-wiring.
