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.
