CPU Units

The modular subrack control system RAVA is designed to implement TCMS in rolling stock. CPU units provide backbone communication of each subrack to various communication lines (Ethernet, MVB, CAN, WTB, TRDP), while at the same time the individual types of communication can be arbitrarily combined.

An important feature of the subrack design is a possibility of redundancy of power supplies, CPUs, and all I/O cards to increase the reliability of the system.
