The PCAN-Repeater DR establishes a galvanic isolation of up to 5 kV according to IEC60601-1 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.
