Область применения
The U 308 A frequency-voltage converter converts a signal, which is present as a pulse train (frequency), to a direct voltage which is proportional to the pulse frequency.
The direction of rotation can be evaluated by connecting two channels, electrically offset by 90 °, so that the DC output voltage is also available with sign.
On account of its 100 kHz input frequency, the converter is also suitable for fast and dynamic drives.
The f/V converter and the preceding rotary pulse encoder are powered by an internal power supply (230 V supply).
The basic function of the U 308 A module can be seen in the figure.
The input signals of channels I and II are available at two decoupled outputs

Дизайн
The U 308 A frequency-voltage converter can be snap- ped onto a standard mounting rail to DIN 46 277 (35 mm DIN rail).
The unit can also be mount- ed directly on a vertical surface, e.g. in a cabinet, by means of two screw fixtures to DIN 46 121 and DIN 436 60.
Dimensions:H x W x D = 75 mm x 99.7 mm x 110 mm (see also dimension drawing).
