AC frequency measuring transducer E858

The converter is designed for linear conversion of alternating current frequency into a
unified DC output signal with the range of change:
- 0 to 5 mA for type E858A;
- from 4 to 20 mA for type E858B;
- 0 to 20 mA for E858C type.
Information is carried by the average value of the output signal.
The converter can be used in automatic regulation and control systems
objects of electric power industry.
The converter can operate in six frequency measurement ranges. Selection of the measuring range
measurement range is selected by setting external jumpers to the inputs of range selection or
by supplying them with logic levels when operating in the remote control mode.
