CAN-Repeater

Passive I- and Y-Repeater for CAN

Expansion of the CAN network

  • Connects 2 or 3 CAN networks
  • Improves the load capacity of the CAN bus with participants
  • Available with or without electrical isolation

Industry-suitable Design

  • CAN interface according to ISO 11898-2, data rate up to 1 Mbit/s

  • Operating voltage range: 8 V ... 30 V

  • Compact housing for DIN-EN carrier rail mounting (TS 35)

Arbitration

  • fast logic ensures complete transparency and flawless arbitration of CAN objects in all connected networks

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.

Arbitration

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