B.1 Introduction to external position detection
WARNING
External position detection system
Versions with flameproof enclosures may not be operated with an external position detection
system with the same type of protection.
In some cases it makes sense to mount the position detection and the controller unit separately.
A separate mounting the case, for example, with continuous and strong vibrations, high or too
low ambient temperatures and nuclear radiation. A universal component is available for this
purpose. It is suitable for part-turn and linear actuators. You will require the following:
One of the following external position detection systems
● Article number C73451-A430-D78 made of polycarbonate or with article number
6DR4004-1ES made of aluminum consisting of:
– Positioner enclosure
– Integrated friction clutch
– Integrated potentiometer
– Various blanking plugs and seals
● An external position detection system with article number 6DR4004-2ES, 3ES or 4ES
comprising:
– Positioner enclosure
– Internal NCS module
– Various blanking plugs and seals
– Integrated SIA module (6DR4004-3ES) or GWK module (6DR4004-4ES)
● NCS sensor for non-contacting position detection 6DR4004-6N.../-8N.
● Potentiometers with 3 kΩ, 5 kΩ or 10 kΩ
● Position sensor with a signal range from 0 to 20 mA
● Position sensor with a signal range from 0 to 10 V
And a positioner
● Positioner in combination with EMC filter module 6DR5..0/1/2/3-0...2/3 or retrofitted as
accessory 6DR4004-6F/-8F.
– An EMC filter module as an accessory is provided in a set along with cable clamps and
M20 cable glands.
