ERbic
® field buscomponents ERbic Profibus ERbic CAN bus ERbic SafetyBus For different ERbic bus sys- tems, the interface connectors combine compact dimensions with horizontal or vertical cable termination.The color coding describes different bus sys- tems, nodes, and terminationversionswith integrated termi-nation resistors. The integrated switch of ERbicswitch versions allows for theflexible configuration of Profibus systems. The switchswitches the termination onand off, and can be externally operated. The MAX housing is made from die-cast metal andis ideal for use in rough envi-ronmental conditions, and for meeting EMC requirements.The MAX housing is alsoequipped with an axial cable output in the connecting direction, and therefore, has aslimline shape.
I/O Connectors I/O Connectors 9 12Mbit/s 9 1Mbit/s 9 1Mbit/s Profibus is the most widelyused field bus. The IP 20 inter- face on the device side is stan- dardized as a 9-pin D-Sub fe-male connector. The maximumdata transmission rate is 12 Mbits/sec. The cable is ashielded, twisted-pair conduc-tor. The cable sheath is violet, and the signal cores are green(A) and red (B). With its com-prehensive program, ERNI provides customers with a wide variety of options. Profibus versions can be ob-tained with an external switch,an IDC terminal, a cage clampterminal, and a screw terminal. Also available are ProfibusNodes, and a Profibus termi-nation with screw terminal and optional programming interface. The CAN bus, originally deve-loped for automobile engine management, is distinguished by its stringent high reliability.Data rates reach 1 Mbit/s. The9-pin D-Sub connector is the interface to the device. In somecases, a version with a shielddecoupling capacitor is avail- able as an option (cable shieldhousing D-Sub). CAN bus versions can be ob-tained with an external switch,a cage clamp terminal, or a screw terminal. Also available are CAN bus Nodes, and aCAN bus termination withscrew terminal and optional programming interface. The SafetyBus p utilizes the advantages of the CAN bus. A protocol has been developed by Pilz that satisfies safety engineering requirements. A larger cable cross section of 0.75 mm is specified to coverlonger distances. Only the 3lines required for the bus are connected in the connector(HLG, H = high, L = low, G = ground).The ERbic SafetyBus p is avail-able with a screw terminal con- nection.
