The incoming bus cable must be connected to X71 IN and the
outgoing continuous bus cable to X72 OUT. If the VS bus coupler
is the last station in the fieldbus connection, meaning that no
continuing connection is required, the remote bus is connected
to X71 IN and X72 OUT is equipped with a “Rugged Line” dummy
plug.

Logic and load supply
See Fig. 7
The following are electrically powered via the “Rugged Line”
X71 IN or X72 OUT plug connectors on the RM65M-DG-IB-L
bus coupler:
W
the valves,
W
the bus terminal,
W
all
input modules and output modules that are aligned to the
bus coupler but not the output modules that are aligned to
the power module.
The US1 and US2 operating voltages should be connected in
accordance with Tab. 13.
See chapter 8.1
The operating voltages given in the electrical data
characteristics must be adhered to.
NOTICE
Wrong polarization
The US1 and US2 voltages are not electrically isolated from
one another. The GND connection for both voltages is bridged
internally. If either one of the voltages has the wrong
polarization, this can lead to a short circuit and can cause
severe damage to the bus connection.
O
Both US1 and US2 need an external fuse!
