CAN repeater CRep Opto

communicationindustrialnetwork

The galvanic decoupling CAN repeater CRep Opto transmits and amplifies CAN signals in a protocol transparent way. Both CAN connections behave like one single physical CAN node. CRep Opto 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 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. 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 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. Extended error suppression, separation of faulty segments Wide power supply range ISO 11898 compatible bus interface Assembly rail fixing, connection by D-Sub9 plugs CRep Opto devices include 2 CAN Segments fed to a male and a female plug of type D-Sub9. The plugs carry the CAN signals and the supply voltage. The following table shows the function of the internally connected CAN interface.
