  • Extended error suppression, separation of faulty segments
  • Wide power supply range
  • Assembly rail fixing, connection by M12 connectors
  • Metal housing

Description

The galvanic decoupling CAN-Repeater CRepOpto/M12 transmits and amplifies CAN-signals in a protocol transparent way. Both CAN-connections behave like one single physical CAN-node. CRepOpto/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 favourable network topology for the application needs the installation costs can be lowered. The maximum data rate can be increased by use of CRepOpto/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 CRepOpto/M12. Each sub network can manage a maximum number of CAN-nodes only restricted by the transceiver driver capabilities. With transmission over long distances CRepOpto/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 occuring errors the integrated error suppression reduces the influence of faulty segments to intact sections.

Technical Data

Layout and Connection

CRepOpto/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. The following table shows the pinout of the M12 connectors.

Pin Name Function
1 SHLD Shield connection
2 VCC Positive power supply
3 GND Ground
4 CAN_H CAN signal line (dominant high)
5 CAN_L CAN signal line (dominant low)

Limiting Values

Parameter Minimum Maximum Unit
Storage temperature -20 +80 °C
Operating temperature 0 +60 °C
Supply voltage -100 +35 V
