External position detection

External position detection system
Versions with flameproof enclosures may not be operated with an external position
detection system.
The aforementioned measures are not adequate in some applications. For example,
continuous and strong vibrations, high or too low ambient temperatures and nuclear
radiation.
The position detection system and the controller unit are mounted separately for these
applications. A universal component is available for this purpose. It is suitable for part-turn
and linear actuators. You will require the following:
● An external position detection system with the article number C73451-A430-D78
● Or an NCS sensor for contact-free position detection 6DR4004-6N.../-8N...
● A positioner
● An EMC filter module with the article number C73451-A430–D23 is provided in a set
The EMC filter module is used for the controller unit whenever an external position detection
system is used instead of the internal position sensor. An external position detection system
is, for example, a potentiometer with a 10 kΩ resistance or an NCS sensor.
