3 General description
The customers' demands for a constant
quality of the produced goods, while at
the same time increasing the quantities,
pose great challenges to the mechanical
and plant engineering industry. At the
same time, globalisation is creating
worldwide value flows and production
chains. Machines and plants that had still
been regionally organised just a few years
ago are now networked worldwide. These
developments extend the requirements
of machine and plant control as well as
of the installed components. An ever
growing number of measuring data need
to be recorded, analysed, evaluated and
saved. This increases the transparency
of the manufacturing process and thus
system availability.
The DC 24 V power distribution is also
affected by this development. The
control voltage supplies all essential
components of the machine or system.
These include, besides programmable
control units, for example actuators and
sensors. Therefore, the control voltage
has a special importance in the entire
production process. Its availability and
stability is crucial for system availability
and quality of the produced goods. The
REX system is equal to the task. It consists
of electronic circuit protectors which are
connected with each other via an integral
connector arm without requiring additional
components. Power supply is via the
EM12 supply module which can supply
the circuit protectors with max. 40 A. The
new CPC12 bus controller additionally
allows access to all system-relevant data
of the superordinate control systems. This
can be via the the PROFINET interface as
well as via an additional Ethernet interface.
The CPC12 connects the circuit
protectors with the superordinate control
unit. Its internal
ELBus
®
interface realises
the connection with the REX intelligent
circuit protectors
1
. The CPC12 allows
entire access on all required parameters
of the electronic circuit protectors, their
control unit and the visualisation of the
device data.
This is made available at the field bus
interface for the superordinate control
unit and also at the third RJ45 interface
for further connection. Thus the system
offers a fully parameterisable protection of
the DC 24 V circuits and ensures selective
overcurrent protection of sensors and
actuators, decentralised peripheral
sub-assemblies etc. and there supply
lines.

To simplify presentation and explanation, the naming of intelligent circuit breakers is limited to the system designation REX. This
designation includes the REX12D and REX22D circuit breakers.
