Digital-Analog-Converter for periodical signals

the period duration of the input impulses of different meteorological measuring sensors is converted into a frequency. The results of this A(D transformation are reiable and proportional to the incoming frequency of voltage and/or values. The pre-setting of parameter is very simple via only 4 keys. Anemometer (1468) or wind sensor (14576 I) e. g. are connectable.
