Features
Items IB IL 24 PWR IN/PS and
IB IL 24 PWR IN/PS-PAC only differ
in the scope of supply (see "Ordering
Data" on page 13). They have the
same functions and technical data.
For reasons of simplification the
designation
IB IL 24 PWR IN/PS will be used in
the following.

Function
6 9 4 5 A 0 0 2
The terminal supplies an Inline station with
voltage if there is no bus terminal. This, for
example, applies to the ILC 200 UNI. The
terminal is supplied with a 24 V DC voltage
(U
24V
), from which the communications voltage
(U
L
) and the supply voltage for the analog
terminals (U
ANA
) are provided.
In addition, the 24 V DC main voltage (U
M
) and
the 24 V DC segment voltage (U
S
) can be
supplied using the terminal.

The terminal interrupts diagonal
routing and the bus connection and is
thus only to be used at the beginning
of an Inline station.

Ground the power terminal
Connect the power terminal to functional earth ground (FE) via one of the FE connections
of connector 3 or connector 4. For this, connect the corresponding contact with a
grounding terminal (see also Figure 4 on page 6).

24 V Segment Supply/24 V Main Supply
The segment supply and main supply must have the same reference potential. Therefore, an
electrically isolated voltage area on the I/O side cannot be created.
The main supply and the segment supply are protected against polarity reversal and transient surge
voltage.
Ensure short circuit protection!
The main supply and the segment supply do not have short-circuit protection.
The user must provide short-circuit protection. The rating of the preconnected fuse must
be such that the maximum permissible load current is not exceeded.
24 V Segment Supply
You can provide the segment supply at the IB IL 24 PWR IN/PS terminal or one of the supply
terminals.
There are several ways of providing the segment voltage at the IB IL 24 PWR IN/PS terminal
(connector 4):
1. You can provide the segment supply separately at terminal points 1.1 (or 2.1) and 1.3 (or 2.3)
(GND) of the power connector (Figure 4 on page 6).
2. You can jumper connections 1.1 (or 2.1) and 1.2 (or 2.2) to tap the supply for the segment circuit
from the main circuit.
3. You can insert a switch between terminal points 1.1 (or 2.1) and 1.2 (or 2.2) to create a switched
segment circuit (e.g., an emergency stop circuit).

The 24 V supply is protected against polarity reversal and surge voltage. These protective elements
are only used to protect the power supply unit.
Ensure short circuit protection!
The 24 V supply does not have short-circuit protection.
The user must provide short-circuit protection. The rating of the preconnected fuse must
be such that the maximum permissible load current is not exceeded.
