Filter function recognizes only high frequency changes.
Filter function recognizes only low frequency changes.
The RD Series Analog Controllers interface to analog sensors and provide ten different measurement modes which can be used for control of machinery, inspection and production lines in an automation environment. High and low pass filters provide selective detection of desired frequency ranges and minimize the effects of high-frequency fluctuations in the analog signal. High-speed sampling rate of 2 kHz enables the detection of any abrupt changes in the input signal. Upper and lower limit set with alarm outputs. A high speed comparator performs differentiation at a 1 ms rate.
