D220C - CAN Repeater

The D220C is a compact CAN repeater that connects two CAN networks to a single logical CAN bus. With this repeater the number of devices on the CAN bus and the range of the CAN bus can be increased. Furthermore, both CAN ports on the D220C are fully galvanically isolated. The repeater is equipped with an FPGA that integrates the glue logic for the functionality. It is fully transparent to any CAN protocol and can therefore be used in a wide range of applications.

The D220C is powered directly from the train battery (24V to 110V). There is no need for an additional DC/DC converter.

The D220C is designed for harsh rolling stock environment and complies with the EN 50155 standard by:

-40 to +70°C operating temperature

coating against humidity

enhanced EMI and vibration robustness


  • Fully transparent for all higher layer protocols like CANopen or J1939
  • Baudrate up to 1Mbit/s
  • Galvanic separation 1kV
  • -40 to +70°C operating temperature
