Electronic circuit protector REX12
A neat and smart connection
REX12,
the new generaltion of electronic
overcurrent protection, combines flexibility
and compact design upon request
with industrial communication via the
point-to-point connection
IO link.
The
REX12
product range offers the suitable
combination of devices, depending on the
application and requirements. The
REX12
exactly meets the technical and economic
requirements of the machine and panel
builders. No additional accessories are
required when connecting the individual
components electrically and mechanically.
This helps save time and money!
The product group consists of the
EM12-T
supply modules with integral
group error signalling by means of a
relay contact and the
EM12D-T IO Link
device,
which transmits a great amount of
diagnostic information to the superordinate
IO link master
in addition to the supply.
It also comprises the single channel and
double channel
REX12-T
electronic circuit
protectors or the smart version
REX12D-T,
both types featuring a modular design to
be mounted side by side.
The 12.5 mm wide modules feature
push-in technology for wiring with
press release buttons and allow no-tool
time-saving and maintenance-free wiring.
The supply modules are designed for DC
24 V and 40 A. They accommodate max.
10 mm² with wire end ferrule as a positive
supply. On the load output side the circuit
protector can be wired with 2.5 mm².

The single channel circuit protectors are
available in all standard current ratings
from 1 A to 10 A. The double channel
models are available in the current ratings
2 A, 4 A and 6 A. This helps protect not
only powerful loads, but also sensitive
loads and smallest cable cross sections.
Failures can clearly be detected and
remedied.
The
REX12
offers brilliant flexibility which
allows upgrades at a later date. The
modular design enables changes of load
currents or
replacement of devices.
Just
open the left and right hinged connector
arm of the circuit protector and remove the
unit in question.
Put in a new unit, close
the connector arm, done!

Up to 16 channels of the smart circuit
protector
REX12D-T
can be connected
to the port of the superordinate
IO link
master
by means of the
EM12D-T
supply module. The specified standard
communication transmits comprehensive
diagnostic and parameter data.
This
ensures maximum transparency
of your machinery and unrivalled
flexibility.
