M-Max 700/AR, designed for installation on locomotives and other railway vehicles to record signals of a continuous Automatic Train Control (ATC) and Interlocking systems directly from a sensor (inductive coil) mounted under a pilot of a locomotive, location-bounded by GPS.

The encoding of continuous ATC signals might have a pulse-numeric modulation as well as a frequency modulation and a phase-difference modulation. Along with the signal, the system is automatically recording all other harmonics within the operational band. This unit works together with the Interlocking system with Tonal Rail Circuits Type 3 (420...780 Hz).

M-Max 700/AR records the location of any failure / malfunctions of ATC and Interlocking systems as well as enabling prevention of possible future failures by analyzing statistical information kept by the system.

The IP65 rated system, housed in a rugged aluminum enclosure with dual shock and vibration protection, is based on proven PC/104 technology. The compact design and low power makes it the ideal solution for signal recording on board.

MicroMax, as a manufacturer of industrial computers, takes a customized approach to each client. Our engineering group can design M-Max systems to fit the specific technical requirements of the customer.
