e-Vision SIL2

CENTRALP develops its products to meet and anticipate the growing safety requirements of the signalization market.

CENTRALP, in collaboration with CLEARSY, expert in safety systems, launches an ETCS baseline 3 DMI meeting the SIL2 requirements of the subset 091 – ERA 3.2. It will be previewed at the ERTMS fair in Milan, on 26 – 28 March at the UIC conference on the evolution of ERTMS.
Available in 10.4’’ and double 8’’, company’s e-Vision+ SIL2 DMI enables the driver to manage ETCS functions, interacting with the train EVC. In the double 8’’ case, during an incident or a failure of a screen, the second one instantly takes care of the entire display without degradation of critical features so that the train can continue to drive in safety.

In this cooperation, CENTRALP ensures the design and manufacture of the equipment and CLEARSY, with its experience in safety, realizes the software security by developing a modern, simple, modular and perfectly safe architecture.

The e-Vision SIL2 project is available in two hardware platforms:
– 1 x 10.4 inches screen
– 2 x 8 inches screens
These platforms will be provided either with a safety framework allowing the integration of the client’s business application or with the ETCS Baseline 3 application developed by CENTRALP and CLEARSY.

Technical features
E-Vision SIL2 is a HMI platform in 8″, 10″ or 12″, with
or without redundancy, which provides SIL2 functions on user interfaces as touch screen and display. It is available with an ETCS baseline 3 DMI application v3.4.0 or as a generic platform for your application.
