The PCAN-Repeater creates a connection between two High-speed CAN buses with galvanic isolation of up to 5 kV. Both CAN channels are decoupled from each other and from the power supply. CAN messages are forwarded 1:1 between the two channels and may be forwarded unidirectionally if required. LEDs display the current bus status. With its DIN rail casing and extended temperature range support, this module is suitable for use in an industrial environment. Note: Due to the CAN protocol, the maximum length of a CAN bus depends on the bit rate. Therefore, a bus cannot be extended with the PCAN-Repeater. The physical total length of the CAN bus is reduced with each built-in PCAN-Repeater according to its signal delay.


  • Two High-speed CAN channels (ISO 11898-2)
  • Galvanic isolation rated up to 5 kV according to IEC60601-1, between both CAN channels and between CAN and power supply
  • Bit rates up to 1 Mbit/s
  • NXP PCA82C251 CAN transceiver
  • LEDs display CAN bus load and CAN errors
  • Each CAN channel can be selectively terminated
  • Listen-only mode for CAN channel 1 or CAN channel 2 can be switched selectively
  • Plastic casing (width: 22.5 mm) for mounting on a DIN rail
  • 3 mating connectors for power supply and CAN connections
  • Extended operating temperature range from -40 to 85°C (-40 to 185°F)
