Automation of platform screen doors and gates (PSD / PSG) with                      SIDOOR ATE530S

Based on standard automation technology and the fast PROFINET connection, both platform screen doors as well as gates can be used quickly, safely and energy-efficiently. Centrally installed firmware updates and compliance with the SIL 2 standard according to IEC 62061 are other important points. The controller can also be used under extreme environmental conditions and is also available in versions for an extended 

temperature range.

Automation of gap filling with SIDOOR ATE530G

The project-specific solutions for sliding or folding steps close the gap between platform edge and train. Safe and independent passenger exchange for handicapped persons or, for example, baby carriages is possible without any problems. The requirements for fast extension and retraction speeds are met with high reliability and compliance with clamping forces.

Automation of interior railway doors with SIDOOR ATD400T

Our control system for interior railway doors complies with all relevant standards: EN 50155 (electrical safety), EN 14752 (in regard to force and energy), EN 50121-3-2 (EMC), IEC 61373 (vibration/shock) as well as the current fire protection standard for components in rail vehicles 

DIN EN 45545-2, HL3 (Hazard Level 3). In addition, there is the time-saving single-button operation for complete commissioning as well as push-to-open and push-to-close functions.
