Details: VBA-4E2A-G2-XE/E2


The VBA-4E2A-G2-XE/E2 is an AS-Interface I/O module with 4 inputs and 2 electronic outputs. Mechanical contacts (for example buttons) or 3-wire sensors (PNP) can be connected to the inputs. The outputs are electronic outputs designed for a load of 1 A per output. The sensors and actuators connected to the module input and output must receive power externally through an auxiliary power source.

The IP67 flat module is ideally suited for use in the field. An addressing socket is built into the module.

The connection to the sensors/actuators is made by a M12 x 1 rounded connector. An LED is available on the top of the module to display the current switching state for each channel. There is also an LED for monitoring AS-Interface communication and to display whether the module has 0 as an address. One LED indicates when the AS-Interface voltage is applied, while a second one indicates external power supply.

In the standard configuration, the base (mounting plate) of the U-G3FF is used to connect the yellow AS-Interface flat cable and the black flat cable of the external auxiliary power. This lower section allows for contact with the flat cable from both sides.

It is also possible to feed in the external auxiliary voltage with the M12 x 1 rounded connectors. In this case, the seal included in the base of the U-G3FF should be placed in the cage for the black flat cable to ensure protection type IP67.

The device includes communication monitoring, which switches power off to the outputs if no communication takes place on the AS-Interface line for more than 40 ms.

An output overload is reported by the "periphery error" to the AS-Interface master. Communication over the AS-Interface remains in effect.
