  • (1888PressRelease) December 22, 2015 - The new Saturn platform is a robust, widely available safety solution. It coordinates remote I/O management systems and is an ideal solution for rail applications. Both easy to configure and efficient, Saturn significantly reduces the amount of cabling and costs that are typically incurred. It is suited for both TCMS (Train Control Monitoring System) use or on platforms and track side applications.

    Saturn is a Commercial-Off-The-Shelf (COTS) platform offering a cost-effective solution to accelerate "time-to-market" and to boost transit rail car projects without incurring the elevated costs and high risks of an Independent Safety Assessment (ISA) process.

    The Saturn platform is a product portfolio built on a generic concept. It supports mixed heterogeneous configurations of SIL0, SIL2, and SIL4 modules on the same unique copper cable or fibre optic-based communication network. Saturn allows system engineers to design fully integrated, efficient, and cost effective I/O management systems for train operations with both safety-critical and non-safety-critical equipment on the same data network. The Saturn platform can be expanded by adding self-contained or custom I/O modules to match any on-board application requirements. It is based on an innovative state-of-the-art dual, redundant ring communication network, and an open safety protocol fully compliant with EN 50159-2 standard.

    "The Saturn concept is inherently flexible and we invite our customers to design and integrate their own Saturn-compliant I/O modules without any limits!" says Thierry Servat, President of ClearSy.

    Saturn can be installed on both new and renovated trains. 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 underground 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 open communications protocol, enabling a 1m/s cycle time. Users may also customise their Saturn system to suit their respective applications.
