SC-FREQCON

Frequency To Analogue Converter

Very High Accuracy

Wide Range of Input Types

Ultra-Compact, only 12.5mm Wide

0 – 250kHz User - Configurable Input Stage

Isolated 4-20mA or Voltage output

Low Cost of Ownership

The SC-FREQCON is a frequency to

analogue converter which can be

configured using switches to perform any

frequency to analogue converting function.

The range of frequency input available is

0–250kHz and any offset can be introduced

on the input. The input can be averaged

over a period between 0 and 45 seconds

with a quickstep option available to

respond quickly to sudden changes in input

frequency.

Typical applications include the conversion

and linearisation of the frequency output

from a turbine meter, or the conversion of

an optical sensor on rotating machinery to

a 4-20mA output of r.p.m.

The operational status of the unit is

indicated by the front panel LED. The unit

can be powered by any supply from 12- 36

Vdc and 12-32Vac.
