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

General specifications

The VAA-4EA-KF2-ZE/R AS-Interface cou-pling module is a industrial cabinet module with4inputs and 4relay outputs. Its design, only 40mm wide, occupies little space in a cabi-net installation. To install the VAA-4EA-KF2-ZE/R, simply snap it onto the 35mm DIN railaccording to EN50022, with the integratedPower 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 to the AS-Interface cable is accomplished bysimply 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.If a master/gateway other than the one in thecabinet housing is used, the connection to the AS-Interface cable is established via thesame terminals. Once the AS-Interface cablehas been connected to the terminals, the AS- Interface signal is automatically transferredto the Power Rail.Power to the module is supplied by the AS-Interface cable and the outputs are poweredexternally (see connection diagram). A pro-gramming professional jack is available for address con-figuration.

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.
