CAN Repeater CRep Opto/M12

CAN Repeater CRep Opto/M12

is a galvanic decoupling CAN repeater in a metal housing, which transmits and amplifies CAN signals in a protocol transparent way.

Special Features

CAN Repeater CRep Opto/M12

  • Galvanic separation of CAN segments
  • Protocol transparent, the CAN error handling is preserved
  • Extended error suppression, separation of faulty segments
  • Wide power supply range
  • ISO 11898 compatible bus interface
  • Assembly rail fixing, connection by M12 connectors
  • Metal housing

Description

The galvanic decoupling CAN repeater CRep Opto/M12 transmits and amplifies CAN signals in a protocol transparent way. Both CAN connections behave like one single physical CAN node. CRep Opto/M12 allows the design of flexible wiring topologies. Star and tree structures as well as stub lines can be realized. By selection of the most favorable network topology for the application needs the installation costs can be lowered.

The maximum data rate can be increased by use of CRep Opto/M12 and a suitable network structure. An increase in the number of nodes in a CAN network is possible through separation into sub networks, each of them connected by CRep Opto/M12. Each sub network can manage a maximum number of CAN-nodes only restricted by the transceiver driver capabilities. With transmission over long distances CRep Opto/M12 allows signal recovering. Through the galvanic separation of the bus segments CAN sections with differing ground potential can be connected. For the most common occurring errors the integrated error suppression reduces the influence of faulty segments to intact sections.

Technical Data

Layout and Connection

CRep Opto/M12 devices include 2 CAN­ Segments one fed to a male and one to a female plug of type M12. The plugs carry the CAN signals and the supply voltage. Each CAN segment needs its own power supply.
The following table shows the pinout of the M12 connectors.

PinNameFunction
1SHLDShield connection
2VCCPositive power supply 24 V
3GNDGround
4CAN_HCAN signal line (dominant high)
5CAN_LCAN signal line (dominant low)
