General characteristicss
- Minimal maintenance. It does not have electronics on the track, nor does it require power.
- High reliability and availability of the installation.
- Immune to electromagnetic fields in railway operation.
- System self-diagnosis, automatically detecting the degradation of the sensory element.
- Low energy consumption.
- Dual fibre optic, bi-directionally illuminated with direction and pitch identification coding.
Other features
- Communications with remote control of detectors: ethernet proprietary protocol e lEC 600 870-5-104 ADIF profile.
- Communications with interlocks: dual ethernet SIL2, EN 50159-1.
- Electromagnetic compatibility: 50121-4: 2007, EN 61000-2-4, EN 60870-2.
