F/A Converter
Functional description
The F/A Converter converts a single puls train to a 4 ... 20 mA output signal.
The output is based on an internal reference frequency selectable in 16 steps. This gives a full output at 16 different pulse rates.
The F/A Converter is optional and must be mounted externally.
