Choke N 120 — 500 mA
The bus devices working voltage is
transmitted via the same cable as the
data. The choke N 120 protects these
data from becoming terminated on
the bus line by the power supply. The
choke picks up the working voltage
on the two outer printed conductors
of the data rail and feeds it to the
two inner printed conductors via
induction. The working voltage is
directly fed to the DIN rail’s two
outer printed conductors by the
N123 power supply unit. Via the

incorporated reset-switch (operation >
10 s), the bus devices are set to their
default setting. This is done by shortcircuiting the bus line and switching
off the working voltage. The choke
resistance is low-ohmic for the direct
current of the working voltage.
As information is transformed to
alternate current for transmission
on the system, the resistance of the
choke N 120 is high-ohmic. Therefore,
the working voltage does not affect
the information signal.
