The functionality of a 16x periphery module is defined via the terminal block, which is
connected to the electronic unit via a secure flap mechanism. In the case of an error you
can exchange the defective electronic unit for a functional unit with standing wiring. At the
front side there are LEDs for status indication. For easy wiring each electronic unit shows
a corresponding connection diagram at the side. The electronic unit provides the slot for
the terminal block for the wiring and contains the backplane bus with power supply for the
electronic and the connection to the DC 24V power section supply. Additionally the elec-
tronic unit has a locking system for fixing it at a mounting rail. By means of this locking
system your system may be assembled outside of your switchgear cabinet to be later
mounted there as whole system.
The terminal block provides the electrical interface for the signalling and supplies lines of
the module. When mounting the terminal block, it is attached to the bottom of the elec-
tronic unit and turned towards the electronic unit until it clicks into place. With the wiring a
"push-in" spring-clip technique is used. This allows a quick and easy connection of your
signal and supply lines. The clamping off takes place by means of a screwdriver.
Please note that no shield bus carrier can be mounted on the CPU
iC921xM-x and a 16x periphery module!
The shield bus carrier (order no.: 000-0AB00) serves to carry the shield bus (10mm x
3mm) to connect cable shields. Shield bus carriers, shield bus and shield fixings are not
in the scope of delivery. They are only available as accessories. The shield bus carrier is
mounted underneath the terminal of the terminal module. With a flat mounting rail for
adaptation to a flat mounting rail you may remove the spacer of the shield bus carrier.
