CAN-CR300
CAN / CAN FD repeater with screw terminals
and 4 channels
The CAN-CR300 is used for galvanic isolation of CAN / CAN FD network segments and to design
tree or star topologies. 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.
CAN and CAN FD interfaces in one device
4 x CAN / CAN FD
Cost savings due to simple wiring
Increased system reliability
Almost no influence on real-time behavior
CAN-CR300
User manual
Display Transmit and defective segment (four duo LEDs, one for
each segment), Power (one LED)
CAN bus interface ISO 11898-2 with CAN choke. Two screw terminals.
Available with and without integrated CAN termination.
CAN bitrates Up to 1 Mbit/s
CAN FD bus interface ISO CAN FD and nonISO CAN FD
CAN FD bitrates Arbitration 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.
Delay typ. 175 ns (corresponds to ~35 m bus length)
Power supply 9-36 V DC, typ. 90 mA, max. 125 mA, through terminals
Galvanic isolation 1 kV DC / 1 sec, 500 V AC / 1 min; All CAN channels
and power supply are galvanically isolated from each other.
Certification CE, FCC
