VAA-4EA-KF2-ZE/TAS-Interface sensor-/actuator module Technical data Function

General specifications

The VAA-4EA-KF2-ZE/T AS-Interface cou-pling module is a industrial cabinet module with4inputs and 4electronic outputs for 115/230VAC. To install the VAA-4EA-KF2-ZE/T, simply snap it onto the 35mm DINRail, according to 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 inputs andoutputs allow "online" maintenance, i.e.while the system is under power. The termi-nals are coded to prevent incorrect connec-tions at the inputs and outputs.If a master/gateway other than the one in thecabinet housing is used, the connection tothe AS-Interface cable is established via the same terminals. Once the AS-Interface cablehas been connected to the terminals, the AS-Interface signal is automatically transferred to the Power Rail.Power to the module and to the inputs is sup-plied by the AS-Interface cable and the out-puts are powered externally (see connectiondiagram). A programming professional jack is available foraddress configuration.

The outputs are de-energised by means ofan integrated watchdog, whenever communi-cation on the AS-Interface cable is inter-rupted for more than 80ms. The watchdogcan be disabled by the parameter bit P0.If a short circuit occurs in the sensor supply,the AS-Interface master indicates an errorand the module disconnects from the AS-Interface.
