[Technology] SATURN, Programmable Rail Safety I/O (SIL0, SIL2, SIL4) Network by ClearSy of France
Based in Aix en Provence and in Paris, ClearSy develops and commercializes electronic and software safety solutions for the rail industry. The French company is now introducing SATURN, a new hardware platform dedicated to managing remote I/O systems for rail.
SATURN is a new platform and a robust, high-availability safety solution. It coordinates remote I/O management systems and is an ideal solution for rail applications. Easy to configure, Saturn significantly trims the wiring and cost requirements to which rail is subject. It is suited for both TCMS (Train Control Monitoring System) use or on the platform and track side applications.
SATURN can be installed on trains, both new and under renovation. It can also be installed on platforms and track side applications; and used to run specific parts of the system, such as switches or platform screen doors / automatic platform gates in subway stations.
The SATURN system is based on a range of remote I/O modules operating at different safety levels (SIL2, SIL3 or SIL4), in which a controller unit manages the ring communication network and an innovative and open communications protocol, enabling a 1m/s cycle time. Users may also customize their SATURN system to suit their application.
