Dependent on the device type, either microswitches or proximity switches are used.
They enable reliable end position feedback and can be equipped with a field bus connection upon request (e.g. AS-Interface, DeviceNet etc.).
The latest generation is self-learning.
These devices recognise the valve end positions automatically during initialisation programming.
No time consuming manual setting of microswitches or proximity switches is necessary, retrofitting to installations or recalibration after servicing work becomes considerably easier.
