CAN / CAN FD repeater with screw terminals
and fiber optic connector

The CAN-CR110/FO is used for galvanic isolation of two segments of a CAN / CAN FD network. As a special feature, the repeater separates a defective segment from the rest of the network, allowing the remaining network to continue working. After the fault has been eliminated, the segment is automatically switched back to the network. The galvanic isolation is provided for the CAN / CAN FD segments as well as for the power supply.


Features and benefits

  • Fiber optic enables transmission in areas with high electromagnetic disturbances
  • CAN and CAN FD interfaces in one device
  • Cost savings due to simple wiring
  • Increased system reliability
  • Almost no influence on real-time behavior

Technical specifications

DisplayTransmit and defective segment (two duo LEDs, one for
each segment), Power (one LED)
CAN bus interfaceISO 11898-2 with CAN choke. Two screw terminals.
CAN variant available with and without integrated CAN termination.
CAN bitratesUp to 1 Mbit/s
CAN FD bus interfaceISO CAN FD and nonISO CAN FD
CAN FD bitratesArbitration rate up to 1000 kBit/s, data rate up to 8000 kbit/s. The data rates are verified by tests. User-defined bit rates are possible.
Attention: The maximum data rate can be exceeded depending on the concrete operating conditions (cable length, settings made, remote stations,…), but it can also not be reached.
Delaytyp. 300 ns (corresponds to ~60 m bus length) between the wire
connection of a FO Repeater through the fiber optic cable to the wire
connection of a second FO Repeater (not including the signal delay
time of the fiber optics, which is ~5 ns/m)
