RAS90 

Track and locomotive balises are certified by independent assessors in accordance with EN standards 50121-3, 50121-4, and 50125-3. RAS90 is developed and certified in compliance with EN 50155, EN 50121-3, EN45545, and EN 61373, and has been certified up to SIL 2.

Although RAS90 is a microprocessor‑based high‑tech system, its maintenance procedures are designed to be as user‑friendly as possible. Fault diagnosis and system checks are performed via a dedicated diagnostic application, enabling efficient troubleshooting and system monitoring. The system also supports self‑maintenance functions, enhancing reliability and reducing downtime. Additionally, peripheral units are supported by dedicated test devices – the speed sensor is tested using the SSTD testing unit, while the locomotive balise is tested using LMI18 and IDTD RC devices.

Connection to other onboard systems is achieved via an isolated CAN bus. Connection to the central diagnostic system (CENDIS) is realised through an xG router or WiFi. Additionally, the system supports Ethernet-to-CAN message translation, enabling communication via both Ethernet and CAN bus and ensuring flexible integration with a wide range of onboard systems.

REC90 is a module developed specifically for event recording and it can be used with PC application RAS90LiveViewer and RAS90Evaluator. All diagnostic data can be archived in ALTPRO central diagnostic system CENDIS.
