VAA-4E-KF2-ZEAS-Interface sensor module Technical data Function

General specifications

The VAA-4E-KF2-ZE AS-Interface couplingmodule is a industrial cabinet module with 4inputs. Itsdesign, only 20mm wide, occupies little space in a cabinet installation. The VAA-4E-KF2-ZE is installed by snapping it onto the35mm DIN Rail per EN50022, with the inte-grated Power Rail.When an AS-Interface master/gateway isused in the cabinet housing, the AS-Interfacesignal is automatically transmitted via thePower Rail. The connection of the module tothe AS-Interface cable is accomplished by simply snapping it onto the DIN Rail.The plug-in coded terminals of the inputsallow "online" maintenance, i.e. while thesystem is under power. The terminals arecoded to prevent incorrect connections.If a master/gateway other than the one in thecabinet housing is used, the connection tothe AS-Interface cable is established via thesame terminals. Once the AS-Interface cable has been connected to the terminals, the AS-Interface signal is automatically transferredto the Power Rail. The module and the inputs are supplied bythe AS-Interface cable (see connection dia-gram). A programming professional jack is available foraddress configuration.
