+24-V Supply of Main Circuit UM
The 24-V voltage for supplying the main circuit UM that is to be fed in at
terminals 2.1 and 2.2 is not used in the IndraControl L40.
It is supplied through all Rexroth Inline I/O modules and forms the main
circuit U
M of the Rexroth Inline modules.
The main circuit U
M starts at the IndraControl L40 or at a power terminal
and is supplied through all following modules up to the next power
terminal. 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.
Several independent segments can be created within the main circuit.
The main circuit provides the main voltage for these segments. For
instance, a separate supply system for the actuators can be set up.
The maximum current carrying capacity is 8 A (total current with the
segment circuit). If the limit for the voltage jumpers U
M
and U
S
has been
reached (total current of U
S
and U
M
), a new power terminal must be used.

In the simplest case, the main voltage U
M
can be supplied at the
IndraControl L40.
The main voltage U
M
can also be supplied via a power terminal. A power
terminal must be used in the following cases:
1 An electric isolation is to be set up.
2 The maximum current carrying capacity of a voltage jumper (U
M
,
U
S
or GND, total current of U
S
and U
M
) has been reached.
