M-Max® 400 RC is a highly reliable compact rugged computer for building all-electric interlocking distributed systems. The system is designed for converting CAN‑interface control signals (twisted pair or single-mode fiber) into relay control signals of railroad automation systems.
The M-Max® 400 RC uses ‘2 out of 2’ architecture for higher reliability of control signals. Two autonomous identical computers inside the M-Max® 400 RC are connected by internal interfaces. External relays are connected to control outputs in a way to get an AND circuit in signal control.
Each computer has an independent power input and an internal uninterruptible power supply (UPS) based on ultracapacitors, ensuring up to 40 seconds of operation with the input power cut off. Depending on configuration the system allows to maintain 12 or 24 paired relays.
