    CAN Repeater

    Passive I or Y Repeater for CAN (Controller Area Network)

    • Linking 2 or 3 CAN networks with or without electrical isolation
    • I Repeater improves participant capacity on CAN
    • Y Repeater forms branch between one and two CAN Networks
    • CAN interfaces differential, designed according to ISO 11898
    • Bit rate up to 1 Mbit/s
    • Repeater delay for determination of CAN bit rate: ca. 14 msec (design '-Opto')
    • Available with electrical isolation of one CAN interface
    • Suitable for CANopen and J1939 higher-layer protocols
    • Compact hat rail module.

    I- or Y- Repeater

    The I-Repeater can be used to improve the participant capacity of the CAN bus or to insert an electrical isolation (only possible in design ‘-Opto’). The Y-Repeater makes a branch from one to two CAN lines.

    Note: Repeaters are primarily used a signal conditioners improving the network communication in eletrically harsh environments (e.g. sparks). Repeater cannot be used to increase the physical network length! 

    Physical Layer

    All CAN interfaces of the repeaters are fully ISO 11898 compliant. Each Repeater is available without electrical isolation or with an electrically insulated interface. The maximum transfer rate is 1 Mbit/s. The bit timing has to be the same at all connections. Each CAN interface has a terminating impedance of 120 ohm in the repeater.

    Line Length

    The total expansion and maximum bit rate of the complex CAN network is determined from the sum of the maximum lengths of sub-networks and Repeaters (eL). Use only one repeater per network.

    Power Supply

    The CAN Repeater is fed by an external voltage in the area of 8 V ... 30 V.

    Arbitration

    A total transparency and the perfect arbitration of the CAN objects in all connected networks is guaranteed by the integrated fast logic.
