Signal conditioners
Frequency transducers for conditioning and converting
frequency type inputs
This range of frequency or pulse type input conditioners / converters can be configured for many types of frequency type inputs including volt-free contacts, current pulse, open collector, sine, square or triangular waveforms, from e.g. proximity switches, flowmeters, water meters, etc.

Frequency to analogue converters
107-10B Frequency to Analogue converter
A frequency transducer for converting frequency and volt-free switch/ open collector outputs into an analogue current of voltage signal. Wide frequency range from less than 0-1Hz up to 0-10Khz. Optional PC software enables range changing, e.g. to suit a turbine meter replacement, and optimisation of digital filtering to suit site conditions. Wall or DIN rail mounting.
Typical applications include converting water meter pulse outputs into a 4-20mA analogue signal.
Pulse isolators / conditioners
112-51 Pulse isolator / conditioner
Conditions a variety of types of pulse input signals and provides a clean, optically isolated and shaped pulse or relay contact output. A pulse splitter version with two relay outputs is also available.Wall or DIN rail mounting.
Typical applications: pulse shaping / stretching, cleaning up noisy signals or contact bounce on mechanical switches, signal level changing.
Frequency dividers
112-25 Digital divider
Divides the frequency of the input signal by an adjustable integer. Two versions are available: two decades (0-99), adjustable via internal switches and four-decades(0-9999), selectable via internal switches and a further ÷10 or ÷100 adjustable by a jumper link. Wall or DIN rail mounting.
Frequency scalers
112-26 Frequency scaler
Scales the frequency of the input signal by an adjustable non-integer number. The scaling factor is set by internal switches, four decades of division (0-9999) and four decades of rate multiplication (0-0.9999). Wall or DIN rail mounting.Two further divisions of 10 and 100 are selected via jumper links.
Typical applications: flowmeter scaling to provide one pulse per unit volume.
Pulse summators
112-60 Pulse summator
Sums up to five digital (pulse) signals.
An optional version of the unit operates as an adder / subtractor. In this mode two outputs are provided for use with an external add / subtract counter.
Wall or DIN rail mounting.
Typical application: summation of integrator pulses from several flow meters.
