Function
The KFU8-FSSP-1.D-Y frequency-voltage/current converter is a device for displaying and monitoring periodic signals, which occur in almost all areas of the automation and processing industry, i. e. frequencies in general and rotational speeds in particular.
Input pulses are evaluated according to the cycle method, i. e. by measurement of the periodicity, and are converted into a frequency or rotational speed by a µ controller. Depending on the measurement range value selected, the µ controller calculates a voltage or current value proportionate to the input frequency and exports this value via a digital-analog converter.
The following analogue signals are available for selection: 0 V ... 10 V, 2 V ... 10 V, 0 mA ... 20 mA, 4 mA ... 20 mA. The serially switched output provides the input frequency which can be subdivided by the adjustable factor (1 ... 9999).
Special consideration was given to the frequently occurring special case of rotational speed measurement during the development of the device. This makes it possible for the display and inputs to be either Hz or in min -1.
In addition, in applications with signal encoders that return multiple pulses per revolution, it is possible to operate automatically at the actual speed of the drive by assigning the number (1 ... 1200).
The frequency/voltage/current converter is supplied with 24 V DC.
All commonly available two- three- or four-wire proximity switches and incremental encoders on the input galvanically separated by an optical coupler are accepted as a signal source. The input signal frequency in Hz or the speed in min -1 - or the output signal voltage in V or current in mA -appears in a 4-place 7-segment LED display on the front of the device. Parameters can be set with 4 buttons underneath the display.
