Description

The PCAN-Repeater DR establishes a galvanic isolation of up to 5 kV within a High-speed CAN bus. Both CAN ports are decoupled from each other and from the power supply. All message traffic including error frames is forwarded 1:1 between both ports. The PCAN-Repeater DR behaves passively and is transparent from the perspective of the CAN bus. LEDs display the current bus status.

The PCAN-Repeater DR finds application in the realization of long stub lines or the galvanic isolation of two CAN bus segments. With its DIN rail housing and extended temperature range support, it is suitable for use in an industrial environment. The PCAN-Repeater DR is designed for use in CAN CC buses, but can also be used in CAN FD buses with data bit rates up to 4 Mbit/s and nominal bit rates up to 1 Mbit/s.

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 DR. The physical total length of the CAN bus is reduced with each built-in PCAN-Repeater DR according to its transit delay.
