Signal conditioners - frequency/pulse
For isolating, converting, splitting, scaling and summing
process signals from frequency / pulse sensors
This range of frequency or pulse type input conditioners / converters can be configured for many types of pulse type inputs including volt-free contacts, current pulse, open collector, sine, square or triangular waveforms, from e.g. proximity switches, flowmeters, water and energy metering, etc.

Frequency to analogue converters
B12-10C Frequency to Analogue converter
Converts outputs from pulse generating transducers into 4-20mA and other analogue signals. Wide frequency range from less than 0-1Hz up to 0-5Khz. 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.
NB The B12-10C replaces the discontinued 107-10B unit
C16-10 Frequency to Analogue converter
Providing a current or voltage output proportional to the frequency of alternating voltage or pulsed input signal, the C16-10 has many uses in applications including water and energy metering and rotational measurements.
- Frequency ranges from 0 - 0.1Hz up to 0 - 5kHz
- Transducer power supplies
- User selectable inputs
- User configurable outputs
- Optional programmable filtering and ranging
- Universal AC/DC powered (85-260 VAC, 24-200 VDC)
- Removable terminals
Pulse isolators / conditioners / splitters
C16-51 Pulse isolator (multi-function)
The pulse isolator may be user configured to provide either:-
- - three separate pulse isolator channels
- - triple output pulse splitter
- - dual output splitter + single channel isolator
Typical applications: water and energy metering, building management systems, etc. where a measurement is required by multiple monitoring systems.
Outputs may be either open-collector (npn) or relays or a mix of the two types.
- - Inputs: Voltage open-collector transistor or volt-free contact.
- - Universal AC/DC powered (85-260 VAC, 24-200 VDC)
- - Removable terminals
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.
