Description
When using a terminal with remote bus branch
(IBS IL 24 RB-T...), please refer to page 14.
nt
s.
The bus coupler connects an Inline station to the
INTERBUS remote bus. It provides the supply voltages UL
and UANA for the connected devices.
om
po
The end plate is supplied with the bus coupler. Place this
plate at the end of the Inline station. The termination plate
has no electrical function. It protects the station from ESD
pulses and the user from dangerous voltage.
A power terminal must be connected after the
bus coupler to supply the main and segment
voltage to the subsequent terminals.

Observe the logic current consumption of each device when configuring an Inline station. It is specified in every terminal-specific data sheet.
The current consumption can differ depending on the individual terminal. The permissible number of devices that can be connected therefore
depends on the specific station structure.
Functional
If the next device is snapped on, the bus coupler automatically configures the
interface.
If the next device is a terminal with remote bus branch, the interface is
configured as a remote bus interface.
For every other device (e.g., I/O terminal) the interface is configured as a local
bus interface with diagnostics.

Power Dissipation/Derating
Using the maximum currents 2 A (logic current) and 0.5 A (current for analog terminals) in the formula to calculate the power dissipation when the I/O is
connected results in the following:
PPERI = 2.75 W + 0.35 W = 3.10 W
3.1 W correspond to 100% current carrying capacity of the power supply unit in the derating curves on page 5.
Ensure that the indicated nominal current carrying capacity in the derating curves is not exceeded when the ambient temperature is above 45°C.
Corresponding to the formula, the total current carrying capacity of the connected I/O (PPERI) is relevant. If, for example, no current is drawn from the analog
supply, the percentage of current coming from the communications power may be increased.
Example:
Ambient temperature: 55°C
Nominal current carrying capacity of communications power and analog supply: 75% according to the diagram
m
ILLogic = 1.5 A, ILAnalog = 0,375 A
PPERI = 2.0625 W + 0.2625 W
co
PPERI = 2.325 W (corresponds to 75% of 3.10 W)
Possible logic current if the analog supply is not loaded:
s.
PPERI = 1.375 W/A x ILLogic + 0 W
PPERI / 1.375 W/A = ILLogic
nt
ILLogic = 2.325 W / 1.375 W/A
ILLogic = 1.691 A

Common Potentials
When providing the 24 V bus coupler supply
separately from the 24 V main supply/24 V
segment supply
Main and segment supply galvanically have the same potential. From the bus coupler onwards, common
ground is led through the potential jumper to the devices as the reference ground GND.
When providing the 24 V bus coupler supply
by jumpering the 24 V main supply/24 V
segment supply
Bus coupler supply, main supply, segment supply, 24 V analog supply, and 7.5 V communications power
galvanically have the same potential. From the bus coupler onwards, common ground is led through the
potential jumper to the devices as reference ground LGND for the communications power and analog supply
and separately as reference ground GND for the supply and segment level.

Electrical Isolation/Isolation of the Voltage Areas (Continued)
Separate Potentials
When providing the 24 V bus coupler supply
separately from the 24 V main supply/
24 V segment supply:
The bus coupler supply is physically and therefore electrically isolated from the main and segment supply.
When providing the 24 V bus coupler supply
by jumpering the 24 V main/
24 V segment supply:
The bus coupler has two interface supplies for the incoming and outgoing remote bus that are electrically
isolated from one another and from the primary/secondary supply.
The interface supplies for the incoming and outgoing remote bus are electrically isolated from one another and
from the supplies.
The main supply is electrically isolated from the interface supplies.

Connect the bus coupler to functional earth ground via one of the FE connections of the connector. For this,
connect the corresponding contact with a grounding terminal (see also Figure 7 on page 14).
In addition, the bus coupler is automatically connected to functional earth ground by snapping it onto a
grounded DIN rail.
24 V Bus Coupler Supply
The bus coupler 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 bus coupler 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.
