Details: VBA-4E3A-KE-ZE/R


The AS-Interface VBA-4E3A-KE-ZE/R I/O module is a switch cabinet module with 4 inputs and 3 relay outputs. The housing, only 22.5 mm in width, takes up little place in the switch cabinet. The VBA-4E3A-KE-ZE/R can be mounted by snapping it onto the 35 mm carrier rail in accordance with EN 50022.

Plug-in terminals are used for connection. 4X terminal blocks (black) are used for the inputs. Double terminal blocks (red outputs, yellow AS-Interface) are used to connect outputs and the AS-Interface. This makes it possible to separate individual actuators or to supply power during commissioning or servicing.

Either the module (from the AS-Interface) or an external power source are used to supply power to the inputs and the connected sensors. One switch in the device is used for switching. The selection of the internal input power supply is displayed on the INT LED. An LED on the front control plate is used to display the current switching state for each input and output.


The device is equipped with communication monitoring that turns off the outputs if no AS-Interface communication has taken place with the device for more than 40 ms.

An overload of the internal input supply is reported by the 'periphery error' to the AS-Interface master. Communication over the AS-Interface remains in effect.
