Passive I- and Y-Repeater for CAN


  • Linking 2 or 3 CAN nets

  • With or without electrical isolation

  • CAN interface acc. to ISO 11898-2, bit rate up to 1 Mbit/s

  • Compact top-hat rail module (DIN-EN rail mounting)

  • Wide power supply range: 8 V ... 30 V

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.

Physical Layer
All CAN interfaces of the repeaters comply with ISO 11898. 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 subnetworks and Repeaters (eL). Only one repeater can be used per network.

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

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