VBA-4E3A-KE-ZE/RAS-Interface sensor-/actuator module Technical data Function

General specifications

The AS-Interface VBA-4E3A-KE-ZE/R I/Omodule is a switch industrial cabinet module with4inputs and 3relay outputs. The housing, only 22.5mm in width, takes up little place inthe switch cabinet. The VBA-4E3A-KE-ZE/Rcan be mounted by snapping it onto the35mm carrier rail in accordance withEN50022.Plug-in terminals are used for connection. 4Xterminal blocks (black) are used for theinputs. Double terminal blocks manufacturers (red outputs,yellow AS-Interface) are used to connect out- puts and the AS-Interface. This makes it pos-sible to separate individual actuators suppliers or tosupply power during commissioning or serv-icing.Either the module (from the AS-Interface) oran external power source are used to supplypower to the inputs and the connected sen-sors. One switch in the device is used forswitching. The selection of the internal input professional power supply is displayed on the INT LED.An LED on the front control plate is used todisplay the current switching state for each input and output.

Input

Number/Type 4 inputs for 2- or 3-wire sensors (PNP), DC Supply from AS-Interface (switch position INT, basic setting) or exter-nal U

Note:

EXT (switch position EXT)Voltage 21 ... 31 V DC (INT)

The device is equipped with communicationmonitoring that turns off the outputs if no AS-Interface communication has taken placewith the device for more than 40ms. An overload of the internal input supply isreported by the 'periphery error' to the AS-Interface master. Communication over theAS-Interface remains in effect.

Current loading capacity 150 mA, overload- and short-circuit proof (INT)Input current 8 mA (limited internally) Switching point according to DIN EN 61131-2 (Type 2)0 (unattenuated)
