Function
The VBA-4E-G11-I-F analog module has four analog current inputs with a range of 0 mA ... 20 mA or 4 mA ... 20 mA.
The power supply to the measurement value generators takes place depending on the position of the internal slide switch, via ASInterface or through auxiliary voltage. The choice of input supply is displayed via the INT/EXT LED.
Measured value conversion and data transfer is provided asynchronously according to the AS-Interface profile 7.3. The resolution of the analog values is 1 µA with a value range of 0 to 20000 or 4000 to 20000. Network interference can be eliminated with a configurable filter (50 Hz/60 Hz) in the A/D converter.
