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

General specifications

The VAA-4EA-KF-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. The VAA-4EA-KF-ZE/R isinstalled by snapping it onto the 35mm DINRail per EN50022, with the integrated PowerRail.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 inputs and outputsare powered externally (see connection dia-gram). A programming professional jack is available foraddress configuration.

Output

Number/Type 4 relay outputs Electrical isolation AS-Interface - Outputs: Industrial safe isolation according to EN 50178 (250 V AC)Output - Output: Safe isolation according to EN 50178 (250 V AC)Contact loading 2 A/30 V DC per output2 A/250 V AC per output

Note:

Lifetime mechanical: 30 x 10
6 switching cycles electrical:1 x 10

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.
