Communication of electronic signal boxes with relay-based railway crossing controller
Example application: Modernization of railway infrastructure systems
Networking electronic signal boxes at railway crossings with relay technology
As part of the gradual modernization of the railway infrastructure, a situation may arise in which an existing relay signal box is replaced by an electronic signal box while the crossing retains its relay technology. In this case, relay technology and digital technology must be operated with each other. This places stringent requirements on data communication in particular.
Phoenix Contact meets the challenge with the help of modular, simple SIL 3 communication via standardized bus systems that also function reliably over a long range of over 6.5 km.
