Details: VBA-2A-KE5-IL/UL


The AS-Interface connecting module VBA-2A-KE5-IL/UL is a switch cabinet module with 2 analog outputs. The housing is only 19 mm wide and takes up little space in the switch cabinet. The module is mounted by snapping it onto the 35 mm DIN rail in compliance with EN 50022.

The connection is made via removable 4-pin push-in terminal blocks. For AS-i+, AS-i-, AUX+, and AUX-, two connections are available in each case; these connections are bridged in the terminal block. If the terminal block is disconnected from the module, the link between these connections is retained. The terminal blocks are mechanically coded.

The power to the outputs and the connected actuators is supplied via the external UAUX voltage source.

The relevant OUT LED displays the current switching status of the outputs. The OUT LEDs also indicate a lead breakage or an output value outside of the value range at the output.


The device is equipped with a communication monitor, which sets the outputs to zero if the AS-Interface does not communicate with the module for more than 40 ms.

The communication monitor can be deactivated via the parameter P0.

The output mode of current or voltage output is configured via the parameters P1 and P3 or via the terminals CON1 and CON2.

A wire break at the current output, an output value outside of the value range, or an overload of the actuator supply cause a peripheral fault. The parameter P2 determines whether a peripheral fault is reported to the AS-Interface master. The communication via AS-Interface remains unaffected.

If an overload occurs on the actuator supply, the outputs are set to zero.
