Protection of electronic interlockings

Electronic interlocking systems are key facilities in railway operations for controlling and monitoring signals and points at stations and on sections of track. A large number of sensors for recording train positions and actuators for controlling the infrastructure are also connected. To exchange the recorded data with other interlockings and central control centres, they are integrated into complex communication networks.

DEHN offers comprehensive protection concepts for electronic interlockings.

Solutions for electronic interlockings

With a comprehensive protection concept for electronic interlockings, especially for signalling and control technology, you can avoid system downtimes and malfunctions. Our universally applicable surge arresters protect signal mast boxes and point mechanisms as well as data and information technology. Always in view: With the LifeCheck condition monitoring system, you can continuously monitor the arresters in the BLITZDUCTORconnect product family. We also protect data networks and Ethernet applications with specific arresters. We also offer comprehensive solutions for external lightning protection and for the earthing of interlocking buildings.
