Electronic module
The terminal module consists of the fol-
lowing functional elements:
sliding mechanism to fasten the elec-
tronic module,
backplane bus with power supply for
the electronics,
connection to the 24 V DC power
supply,
staircase-shaped terminal block for
wiring,
safe locking system for fastening on
a mounting rail.
This locking mechanism allows you to
mount your Cube20S system outside the
control cabinet and fix the complete sys-
tem later in the control cabinet.
The functionality of an expansion module
is defined over the electronic module.
If the electronic module is defective, it
can be replaced while wiring is kept.
There are LEDs indicating the status
on the front side.
To facilitate wiring, there are wiring di-
agrams on the front and on the side
of each electronic module.
