Frequency/pulse converters
This category covers a diverse range of
instruments for frequency /pulse type inputs i.e. volt-free contact, voltage pulse
input, current pulse input, open collector transistor pulse, sine, square or
triangular waveforms, from e.g. proximity switches, turbine meters, pulse
output type flowmeters, etc.
The
Frequency to Analogue Converter
Type 107-10B provides an isolated analogue output signal proportional to
the frequency of the input signal. Applications include signal conversion for
water meter pulse units and turbine meters.
The Pulse Isolator Type 112-51 isolates and
conditions the input signal and provides a noise-free pulse, open collector or
relay type output signal.
The Frequency Scaler Type 112-26 scales the
frequency of the input signal by a non-integer number and provides a pulse,
open collector or relay type output signal.
The Frequency Divider Type 112-25 divides the
frequency of the input signal by an integer number and provides a pulse, open
collector or relay type output signal.
The Digital Summator Type 112-60 sums up to five
pulse input signals and provides a pulse, open collector or relay type output
signal. |
