Door Control Systems for Railway Applications
The product-specific application/requirement lies in complying with the special railway requirements concerning functional safety.
Interior railway doors have a closing spring which must always bring the door into the "CLOSED" position. This applies to either side, even when a train car is inclined at 10°.
These specific operating states are handled by the door controller.
See the PDF below for an overview of automatic door controllers for railway applications.
