The M-Max® 400 ST/USO is an error‑free rugged computer for on‑board and off-the-shelf applications. It provides error-free signaling information processing, based on 2-out-of-2 architecture.
The M-Max® 400 ST/USO contains two identical subsystems connected to each other via internal interface. Each subsystem has its own processing core and a UPS employing an intelligent ultracapacitor-based charging device.
The M-Max® 400 ST/USO’s two independent CPUs form a vital processing core and perform calculations (such as interlocking logic) in different ways. Once per cycle they are synchronised with each other to exchange data and perform consistency cross-checks.
The UPS ultracapacitors provide the system with 70 seconds of backup power. The system is designed for use on stationary objects within the railway infrastructure.
MicroMax, as a manufacturer of industrial computers, takes a customized approach to each client. Our engineering group can design M-Max® systems to fit customer-specific technical requirements.
