VBA-4E2A-KE1-Z/E2AS-Interface sensor-/actuator module Technical data Function

General specifications

The VBA-4E2A-KE1-Z/E2 AS-interface cou-pling module is a professional cabinet module with4inputs and 2electronic outputs. The hous- ing, only 22.5mm in width and 48.5mm inheight, takes up little place in the switch cabi-net. The module is mounted by snappingonto the 35mm DIN rail in accordance withEN50022.Plug-in terminals are used for connection. 4-way terminal blocks manufacturers (black) are used for theinputs. The connection of the outputs and theexternal auxiliary supply and AS-Interface is made through the 2-way terminal blocks (out-puts black, auxiliary voltage gray and AS-Interface yellow). This makes it possible toseparate individual supplier of actuators or to supplypower during commissioning or servicing.The supply of the inputs and the connectedsensors occurs internally via the module(from AS-Interface). An LED on the front con-trol plate is used to display the current switching state for each input and output.

Note: The device is equipped with a watchdog,which switches the outputs to their de-ener-gized state, when on the AS-interface cable is no communication for more than 40ms.An overload of the outputs is reported by the'periphery error' to the AS-Interface master.Communication over the AS-Interface remains in effect.
