f/U Converter and Signal Converter Frequency >>> Analog / Serial

The devices shown here are used to convert frequencies into analog standard signals (V or mA) and also represent the converted values ​​via a serial output interface. The f/U or f/I signal converters, that are provided for installation in a control cabine, typify high reliability, easy operation, precise conversion and high frequency ranges. Numerous of programmable additional functions round off the respective functional range. The snap-on housing for top hat rail (according to EN60715) allows a quick and easy assembly.

Further possibilities for converting frequencies into analog signals and/or serial formats are also available with our indicators of the DX series (see tachometers).

Multifunctional unit with operating modes for incremental or SSI absolute encoder.
For incremental encoder: Operating modes for frequency converter or position converter (pulse counter).
Functions as linking (e.g. A+B), scaling, filtering, start-up supression ... etc.
