I/O Units – cards
The Modular Subrack Control System RAVA is designed to implement TCMS in rolling stock. There are wide series of cards with digital or analogue inputs/outputs. Communication to train bus networks provides CPU card with a variety of communication lines (Ethernet, MVB, WTB, CAN).
An important feature of the sub rack design is a possibility of redundancy of power supplies, CPUs, and all I/O cards to increase the reliability of the system.
