i103 - CPU Module with CAN

The central processing unit i103 is the core of all CANioniaTM systems. The space-saving form factor allows the design of a compact train controller unit.

Enhanced processing power for any application is provided by the integrated high-performance ARM® Cortex™-A8 processor (core speed of up to 800 MHz) and 256 MB DDR2-SDRAM. Accessing the CAN train bus is done directly, without any additional card.

The module offers a fast and secure point-to-point connection with a maximum of 10 (optionally 27) extension modules (power, input/output or communication). In this way, small and large train applications (I/O count) can be addressed easily with one central unit.

A built-in supervisory mechanism called "Condition Monitoring" can detect and record any defined device status, such as overtemperature, overcurrent, etc. as well as selected user-defined values.

The service interfaces, through Ethernet and USB, offers quick access to diagnostic information and all recorded data.

Developing the train management application is done easily and timesaving by one of the five methods defined by IEC 61131.

The i103 is designed for harsh rolling stock environment and complies with the EN 50155 standard by:

  • -40 to +85°C operating temperature
  • coating against humidity
  • enhanced EMI and vibration robustness


  • High-performance 32bit ARM® Cortex™- A8 processor
  • Built-in supervisory mechanism
  • 100 Mbit "Serial Star Controller": no need for physical module addressing
  • Up to 10 (optionally) 27 extension modules
  • Integrated CAN 2.0 controller; fully compliant with the ISO 11865 standard
  • Detailed diagnostics through Ethernet
  • -40 to +85°C operating temperature
