Manufacturer: Kontron
Kontron TRACe M304-TR

Kontron TRACe M304-TR is an EN50155 certified fanless Operational Computer. This "M" version is specifically designed for Train Management. The M304-TR version is based on a COMExpress© CPU module featuring Intel®  Atom E3845 quad-core @ 1.91 GHz (Bay  Trail). It has been designed to ensure stable operation in harsh environments. Offering MVB and Ethernet field busses, Kontron TRACe M304-TR is the ideal building block for any Train Control Monitoring System

  • Kontron TRACe M304-TR allows communication between equipment in each coach, and they can control and monitor doors, air conditioning, seat reservation, light, power, brakes, its MVB interface (up to Class 4) features to process data,
    message data (opt.), bus administrator (opt.) on EMD/ESD+ physical interfaces.
  • Kontron TRACe M304-TR offers 2 independent Gigabit Ethernet LAN through isolated and lockable M12 connectors. Then TRACe M304-TR can be used as an Ethernet-MVB gateway.
  • Moreover, TRACe M304-TR features 1x WLAN 802.11 a/b/g/n Wi-Fi network interface

The Kontron TRACe M304-TR features a wide range of power supply (from 24 VDC to 110 VDC). Its front plate is dedicated to the operational connectors (certified I/O according to EN50155 standard: Ethernet, Serial ports, Audio, Digital Inputs and
Outputs) whereas the rear plate hosts maintenance connectors (DisplayPort, USB, Serial, Ethernet). Internally, Kontron TRACe M304-TR also provides 2 x 2.5" SATA disks connections.

TRACe M304-TR has been designed to support a comprehensive health management capability, thanks to sensors and a microcontroller for system health monitoring. The integrated microcontroller monitors boards and in-box ambient temperature, voltages, current and even manage Vital Product Data (P/N, S/N, EC Lvl…) of main components. Health management middleware by Kontron covers all the vital resources of TRACe to report, log, and transmit any out of specs parameters and/or any failures at power-on and during operations of TRACe M304-TR.
