+24 V Supply of Segment Circuit US
The segment circuit supply Us 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 L40 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
provided. You can use several segment terminals within a main circuit
and thereby segment the latter. The reference to ground is the same as
that of the main circuit. Thus, you can realize within the station differently
fused electric circuits without any external cross wiring.
The voltage in the segment circuit is 24 V DC.
The maximum current carrying capacity is 8 A. If the limit for a voltage
jumper U
M
has been reached (U
M
, U
S
or total current of U
S
and U
M
(GND)),
a new power terminal must be used.
The segment voltage U
S
can be provided in various ways:
1 You can feed in the segment voltage at the IndraControl L40 or at
a power terminal.
2 You can tap the segment voltage from the main voltage, either at
the IndraControl L40 or at a power terminal using a jumper or a
switch.
3 You can use a segment terminal with fuse. In this terminal, the
segment voltage is automatically tapped from the main voltage.
Note: At the 120 V and 230 V voltage levels, it is not possible to set
up segments. In this case, only the main circuit is used.
Special power terminals must be used.
