CAN CC and CAN FD Repeater for Bus Segment Decoupling

This PCAN-Repeater features two CAN ports with 5 kV galvanic isolation between the two and the power supply. It supports both, CAN CC and CAN FD buses, using bit rates from 14 kbit/s up to 8 Mbit/s. Suitable for applications in industrial environments with no configuration required.

All CAN messages and error frames are forwarded 1:1 between both ports, enhancing the quality of the CAN signals. The DIN rail mounted PCAN-Repeater allows the galvanic isolation of two CAN bus segments and the realization of long stub lines, even with multiple CAN nodes.

From the perspective of the CAN bus, the repeater is transparent, just like a cable.


  • Two High-speed CAN ports (ISO 11898-2)
  • Comply with CAN specifications CAN CC (classic CAN 2.0) and CAN FD (ISO and non-ISO)
  • CAN bit rates from 14 kbit/s up to 1 Mbit/s
  • CAN FD bit rates for the data field (64 bytes max.) from 14 kbit/s to 8 Mbit/s
  • CAN transceiver TI TCAN1044 or compatible
  • Connections for CAN via 4-pin and power supply via 3-pin push-in spring terminal blocks (Phoenix)
  • Galvanic isolation rated up to 5 kV according to IEC 60601-1, between both CAN ports and between CAN and power supply
  • Each CAN port can be selectively terminated via switches at the housing front
  • LEDs indicate power supply, CAN traffic, and transmission errors on physical level
  • Automatic disconnection of a defective CAN segment and reconnection once the fault has been resolved; for example, due to a short circuit or a CAN node with broken transceiver
  • Transit delay about 175 ns, which corresponds to a cable length of approximately 35 m
  • Voltage supply from 10 to 30 V
  • Plastic housing (width: 27 mm) for mounting on a DIN rail (EN 50022 standard)
  • Extended operating temperature range from -40 to +85 °C (-40 to +185 °F)

*Please 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.
