The Spectec Frequency to Current and Frequency and Voltage converter is adaptable to many applications with its capacity to operate in environments with a wide temperature range, plus their ability for field selection of a wide variety of input voltages from magnetic pickup speed sensors and transducers and output variables (as FTC or FTV converter configuration).
The power supply input on all the signal converters covers a wide range of commonly used DC power without any need to select or adjust with protection against reverse polarity wiring. All models have a SPAN and ZERO adjustments to make them easy to calibrate to almost any measurement range, with virtually no interaction between the adjustments. All outputs are fully protected against short circuits to supply, ground or signal out.
Model 4026 Freq to Current or Freq to Voltage Converter
The Model 4026 freq to current or freq to voltage converter is very versatile with field selectable inputs and outputs. The field selectable frequency to current output for it to be set at either as a 4-20mA converter (or 10-50mA output). In the freq to voltage converter configuration, the outputs are 0-5V or 0-10V. The scale of the output is proportional to the frequency of the input signal.
Model 4027 Frequency To Current Converter
The Model 4027 frequency to current signal converter is a 4-20 mA with a field selectable low or high frequency input configurations to fit most applications. This 4-20 mA converter can be used with either 2-wire or 3-wire power supply configuration.
Model 4028 Freq to Voltage Converter
The Model 4028 freq to voltage converter has field selectable inputs to fit high or low frequency applications. Power inputs can be configured for either a 2 or 3-wire power supply.
