Function
This terminal can be used to create a remote bus
branch from an Inline station. It can also be used
to integrate remote devices (e.g., display fields,
keypads, motor starters with IP 65 protection or
sensor/actuator boxes) into INTERBUS via an
Inline station.

The terminal for connecting a remote bus branch
must be positioned directly after a bus terminal,
a control terminal, or a terminal with remote bus
branch. Directly means that there must be no
bus device between the bus terminal/control
terminal and the terminal with remote bus
branch.

Only one remote bus branch terminal may be
used within an Inline station with an

Electrical Isolation/Isolation of the Voltage Areas
Common Potentials
The 7.5 V communications power, 24 V analog supply, 24 V bus terminal supply and the 5 V
communications power of the remote bus branch terminal share a common potential.
Separate Potentials
The communications power ground is jumpered with the ground of the 7.5 V communications power
for the bus terminal power supply unit.
The interface supply for the remote bus branch is electrically isolated from all other potentials.
The I/O supply is always electrically isolated from the interface supplies.
