Function: VBA-4E3A-G20-ZEL/E2L-P11

The AS-Interface I/O module VBA-4E3A-G20-ZEL/E2L-P* is a field module with 4 inputs for 3-wire sensors and 3 electronic outputs. The outputs are overload and short-circuit protected.

The compact housing can be installed directly in support profiles or conduits. The connection to the AS-Interface network and power supply is made using the AS-Interface flat cable and insulation piercing technology. The pivoted flat cable guide is secured using a snap-fit. No tools are required.. The inputs and outputs are connected via cable outputs with M12 round plug connectors. Power for the inputs and outputs is provided by the external auxiliary voltage UAUX.

The current switching state of the inputs and outputs is indicated by the IN and OUT LEDs. The PWR and FAULT LEDs indicate the status of the AS-Interface (normal operation, communication error, peripheral fault, address 0). The AUX LED indicates the external power supply.


The communication monitor of the module deactivates the outputs if the AS-Interface does not communicate with the module for more than 40 ms.

A signal indicating an overload of the outputs or the input supply or the absence of the external auxiliary voltage is also transmitted to the AS-Interface master via the 'peripheral fault' function. Communication via the AS-Interface continues.
