Operating principle of the device
3.2.1
Principle of the device
The safety controller UE 440/470 enables easy integration of several safety and standard
sensors or input devices, other input devices or actuators in a safety application. With this,
you can...
$
implement individual safety applications.
$
implement two independent safety applications.
$
implement two safety applications bound to one another.
Within a safety application, the safety controller processes specific signals of optical and
tactile sensors.
The safety controller also expands the functions of connected systems, such as C 4000 or
S 3000 (PSDI mode, simultaneous protective field monitoring).
Using the Configuration & Diagnostics Software (CDS), you can link the connected
components to one another. Predefined software function modules used to implement
your safety application are available in the CDS for this purpose.
