Keyence Analog Sensor Controllers RD Series

Cat. No. RD-CAnalog Sensor ControllerRD SeriesSix unique and useful functions give the RD superior flexibility andease-of-use to expand analog sensor applications.Features❏ Six unique functions including a linearizer,high-/low-pass filters... and moreThese six useful and convenient functions eliminate noise interferenceor other undesired components, ignore analog signal componentswith frequencies above or below a specified level, andlinearizes the analog input signal for increased accuracy.❏ High-speed sampling rate of 2,000 c/sEnsures accurate measurement even on high-speed lines.❏ Easy-to-read three-color LED displayDisplays green when the measurement value is within the tolerancelimits, orange or red when it is not. Large LED characters allow youto easily read measured values and to differentiate between acceptableand unacceptable products even from a long distance.❏ Quick and easy setting of tolerance andother valuesAll settings can be performed quickly and easily using the RD’s tenoperation keys.

RD SeriesA high- and low-pass filter combined with the linearizer functiongive the analog sensor signal unparalleled accuracyLinearizer functionThe RD series provides up to32-point calibration for analogsignals input from the sensor,enabling the input signal can beprecisely regulated. And up tofour sets of correction valuescan be stored.Raw dataLinearized dataLinearized data outside|measuring rangeRaw data outsidemeasuring rangeHigh-pass filterBy removing the low-frequencycomponents of the analog inputsignal, gradual changes in thesignal are ignored, allowing onlysporadic fluctuations to bedetected.Filtered data showing height differenceonly (height is ignored)Data showing heightdifference and heightData showing number ofgear teeth and eccentricityFiltered data showing number of gearteeth only (eccentricity is ignored)Low-pass filterBy removing the high-frequencycomponents of the analog inputsignal, high-frequency fluctuationsin the signal are ignored,allowing only gradual changes tobe detected.Filtered dataFiltered data showing eccentricity only(gear teeth are ignored)Data containing noiseData showing gear teeth and eccentricity

With the RD, tolerance limitscan also be set to the actualallowable dimensions.ApplicationActual target dimensions can bedisplayed, making visual checkseasier. This results in increasedefficiency for setting or checking.Automatic peak/bottomdetection functionThe RD will detect if the inputvalue falls below the peak value orrises above the bottom value by aspecified margin.ApplicationUseful for detecting a camshaftposition or for targets with eccentricity.Auto-peak/auto-bottomfunctionWithout the normally requiredsynchronous signal, the latestpeak or bottom value is alwaysretained.ApplicationUseful for controlling the peak orbottom values of all products ineach lot, or of all products manufacturedeach day.The input range can be switchedto ±5 VDC, ±10 VDC, or 4 to 20mA. The RD series has “X + Y”and “X - Y” functions, which areexcellent for measuring targetthickness or height difference.AXYFive-level tolerance settingsFive tolerance levels (HH, HI, GO,LO, and LL) can be set, and up toeight sets of tolerances can bestored. The current set of tolerancescan be easily switched toanother set, using an external signal,during target changeover. Inaddition, the current tolerance valuescan be displayed with a singletouch. The hysteresis for the tolerancescan also be set.RS-232C interface (RD-50R)The RS-232C serial port is convenientfor transmitting measuredvalues to a PLC or PC, or toremotely operate the RD-50R.. . . and moreThickness=A– (X+Y)
