The F to V/mA Converters (Model No. XF100 & XF200) are Microcontroller based units, designed to accurately measure the input frequency in the low frequency input range applications. The units operate on the principle of time interval measurement of low frequency input waveforms

Measurement accuracy better than +/- 0.1% is achieved due to high frequency timing clock used internally for time interval measurement. Frequency measurement result is available as fast as two complete cycles of the input waveform at frequencies lower than 10 Hz.

The system also consists of a special waveform conditioning front end circuit, which is able to measure Input Sinewave voltage variations from 0.5V to 28 V AC rms over input frequency range.

XF100H & XF200H modules are offered which have high voltage input capability desired in Power line Frequency measurement applications. The input voltage range varies from 15V to 500V AC rms in these modules.

Analog Output 0-10V/4-20mADC is available, proportional to input frequency range.
