What Are Signal Conditioners?With the variety of process control systems available, it isoften necessary to convert an input signal into a formatthat the system will accept. Signal conditioners takesignals from an assortment of field instruments such asthermocouples and RTDs, and convert those signals intoany of several standard instrument signals (1-5 V,4-20 mA, etc.).
Signal conditioners are also beneficial to the accuratetransfer of these signals and the elimination of groundloops.
Ground LoopsThe key to process control is accuracy; both in measure-ment and in signal conditioning. The biggest and mostoverlooked threat to effective process control is thepresence of ground loops. Whenever analog data istransferred through long cable runs, there is a highprobability that ground loop problems will occur. A groundloop exists when multiple earth ground connections aremade in a system. A difference in potential between thegrounds (Vgnd) generates an extraneous current flow in thesignal conductor. The result is commonly known as noise.In its mildest form, noise in the signal line causes mea-surement offsets, incorrect sensor readings and generalsignal corruption. In its most severe form, however, noisecontamination can deteriorate communication to a pointwhere control of the process is lost.
P+F Signal ConditionersPepperl+Fuchs signal conditioners utilize the latesttechnology, offering unparalleled protection against groundloops while maintaining optimum signal accuracy. There arethree basic types of KF signal conditioners:
Loop Powered Repeaters/Isolators: Loop-poweredrepeaters do not require a separate power supply.Available in single and dual channel models, thesetransformer isolated signal conditioners transfer analogDC signals with each channel working as a DC isolator,providing 2,500 VDC isolation between the input andoutput.
Analog Isolators: These units require a separatepower supply and provide a linear DC outputproportional to the input signal.
Limit Alarms: This class of signal conditionersprovides two ‘Form C’ relay outputs with adjustablehigh and low switchpoints and selectable control safeand normal operation. They also require a separatepower supply.
The latter two categories are fully field-configurable andprovide 1,800 VDC isolation separating input, output andpower supply. Input and output ranges, modes ofoperation, switchpoints, etc., can be programmed in thefield via DIP switches on the side of the housing. Input,zero and span are adjustable by potentiometer to 50% forall input ranges. The wide-ranging capabilities and field-configurable settings allow for numerous options in adiverse range of applications.
All P+F analog isolators and limit alarms also contain theASIC chip for increased reliability. ASIC (ApplicationSpecific Integrated Circuitry) substantially reduces failuresby virtually eliminating discrete components and theirsolder joints where most faults occur. Printed circuit boardconnections are reduced by 70%.
Isolation between the ground circuits is essential to theprevention of ground loop currents and, therefore, theelimination of noise. Signal conditioners provide thenecessary isolation as well as amplification, filtering andlinearity corrections.
The KF HousingFor simplicity of installation and maintenance, P+F signalconditioners are designed in the compact KF housing,featuring snap-on DIN rail mounting and plug-in connectionterminals that eliminate lead coding and extensive hardwiring. Power is applied to the modules via conventionalwiring or through the use of the P+F Power Rail. In smallinstallations, the supply can be daisy chained from onesignal conditioner to the other. For medium to largeinstallations, however, Power Rail's compact designsimplifies installation and maintenance.
Power Rail snaps directly onto a standard 35 mmDIN rail and is designed to supply power to P+Fsignal conditioners and transformer isolatedbarriers. Contacts on the bottom of the KFhousing connect with two heavy power conduc-tors in the Power Rail. A power feed moduledelivers 24 VDC at 4 A to Power Rail whileprotecting the installation by way of a 4 A fuse.The modules are then automatically powered asthey are snapped onto the rail. Daisy chain wiringis eliminated, as is the possibility of lead break-age. Through Power Rail, the installation is wiredfor future system expansion (see UPR-02 PowerRail Mounting on page 57 for details).
Power RailModel: UPR-02
ApprovalsProducts displaying the CE mark comply with European Conformity directives; these products willoperate with other electrical components without causing or being susceptible to electromagneticinterference. Eventually all P+F signal conditioners will carry the CE mark. For more informationregarding CE and other approvals for signal conditioners, contact P+F.
ThermocouplesA thermocouple is a device used tosense temperature. It is inexpensiveand with the various types available,covers a wide range of measuredtemperatures. Thermocouples areconstructed of two dissimilar metalswhich generate a millivolt signalvarying with temperature.
I/P ConvertersAn I/P Converter is commonly knownas an electro-pneumatic transducer orcurrent to pressure converter. Itconverts a DC milliamp signal to aproportional pneumatic output signal.This pneumatic signal is frequentlyused to position a control valve.
TransmittersA transmitter can be described as a deviceused in a control system that senses andconverts a process variable such astemperature, level, pressure, flow, etc., toan electrical signal proportional to the valueof the sensed variable. The electrical outputis typically a 4-20 mA signal.
RTDsAn RTD (resistance temperature detector)converts temperature into resistance. Anexample of resistance change is 0.385ohms/°C for a 100 ohm platinum RTD.
SolenoidsA solenoid is an electrically actuated valvethat allows full flow or no flow of gases orliquids.
AlarmsAudible alarms (horns or buzzers) aredevices used to signal an event has takenplace.
Frequency InputsMany devices such as flow meters, sensorsand feedback loops use an alternatingpotential to transfer information. The rate atwhich the potential is changed, or frequencywill represent the speed, position orintensity of a process.
Voltage Current SignalsA signal conditioner transfers and isolatesinputs such as millivolt, pulse, 4-20 mAand other current and voltage signals.

The KFDX-HZ accepts a frequency input andprovides a fully isolated proportional DCcurrent or voltage output. This isolator alsoeffectively eliminates ground loops with 1,800VDC isolation separating input, output andpower supply.
OperationThe input range can be configured in the fieldfor any frequency span from 2 Hz to 10,000Hz via DIP switches on the side of thehousing. The output is configurable for fiveranges: 0-5 V, 0-10 V, 0-1 mA, 0-20 mA or4-20 mA.
The KFDX-HZ is simply configured viapushbutton rather than a zero and spanpotentiometer. Set the input frequency spanby applying the maximum and minimumfrequencies to the system and pressing theCAL button while the INPUT LED is lit.
Frequency InputCurrent/Voltage Output
Model NumberKFDX-HZ
Diagnostic LEDsThe KFDX-HZ is outfitted with three LEDs:LEVEL (green), INPUT (yellow), and OUT-PUT (red).
LEVEL (LVL) LED (Green) is on or flashingwhen an input signal is applied or when thecalibration mode is engaged. During normaloperation, the LED intensity varies with thefrequency of the input signal.
INPUT (IN) LED (Yellow) remains on whenthe unit is in the input programming mode.
OUTPUT (OUT) LED (Red) indicates outputprogramming modes.
ConfigurationThe KFDX-HZ isolator is factory configured as follows:
Input range: 0-1000 HzSensitivity: 1 Vp
Output range: 4-20 mA
To reconfigure the input/output parameters, refer to Table 1and Table 2 to adjust the SW1 switch to the desired inputand output characteristics.
WARNING!To prevent damage to the unit, turn off the power before
configuring the DIP switches.
1. Determine the desired output voltage/current rangefrom Table 1 and set SW1 positions 1-8 as shown.
2. Position SW1 switch 10 for the input sensitivity. Setthe sensitivity to LOW for input pulse signals from50 mV to 1 V (50 Vrms max.) amplitude or to HIGH forinput pulse signals from 0.5-10 V (150 Vrms max.)amplitude (see Table 2 ).

Calibration Flow Chart
Calibration1. After configuration is complete,
connect a calibrated frequencysource as the input. The outputterminals of the KFDX-HZ should beconnected to the field device or aload value approximately equal tothat of the device. Apply power.
Note: Calibration should take placein the application area. Allowapproximately 1-2 hours forsystem warm-up and thermalequilibrium. Removal of powerat any time prior to step 8 willrestore previous settings andcalibration.
2. Apply the maximum input frequency
to the system; the green LEVEL(LVL) LED should be on or flashing.If thisdoes not occur, turn thesensitivity potentiometer counterclockwise until the LVLLED flashes. Note the LVL LED may not appear to be onif the new range is less than 10% of the previouslycalibrated range.
3. While the green CAL LED is illuminated press the CALbutton once to initiate the calibration mode. The yellowand green LEDs should be illuminated.
4. Input the maximum frequency desired and store it (if notdone previously) by pressing the CAL button. Only theyellow LED should be lit.
5. Input the minimum frequency desired and store it bypressing the CAL button. Both the red and green LEDsshould be lit. The most reliable way to input 0 Hz is toshort circuit input pins 1 and 2. To omit the outputadjustment stage (steps 6 and 7), press the CAL buttontwice after completing step 5.
6. To precisely adjust the maximum output range, increasethe input frequency until the output reads within ±0.1%of the maximum voltage or current range selected andpress the CAL button to store. The red LED should nowbe lit.
7. To adjust the minimum output range, lower the inputfrequency until the output reads within ±0.1% of theminimum voltage or current range selected and pressthe CAL button to store. All three LEDs (green, yellowand red) will illuminate. The green LED will be dim.
8. Press the CAL button again to exit the calibration mode.The green LED should be flashing with increasingintensity as input frequency increases.
9. Check the minimum and maximum input to outputcalibration. Repeat steps 1-8 as necessary toachieve the desired accuracy.

These signal conditioners accept analogDC inputs and provide two independentform C contact outputs. They are fullyfield-configurable and offer 1,800 VDC3-way isolation. A separate DC powersupply is required.
The KFDA-DCI accepts a DC current inputand provides two adjustable contact outputs.This limit alarm also effectively eliminatesground loops with 1,800 VDC isolationseparating input, output and power supply.
OperationSetpoints can be configured as HI or LOin selectable controlsafe or non-controlsafeoperating modes. The KFDA-DCI relies ondeadband (hysteresis) and constant samplingof the input to prevent false switching whenthe input varies slightly on either side of thesetpoint. The input must remain beyond thesetpoint for 100 ms, uninterrupted, to qualifyas a valid trip condition. To return the alarmto an untripped condition, the input signal mustbe outside the deadband and remain there for100 ms. This time-based dynamic deadband, inaddition to the evaluation of hysteresis, improvessetpoint stability. Select unipolar operation forinputs that do not change in polarity.
For HI trip, the relay changes state when theinput current rises above the setpoint current,and remains in this state until the input signalfalls below the deadband. In the case of LO trip,when the input signal falls below the low setpointvalue, the relay changes state and remains thatway until the input signal climbs above thedeadband. For proper deadband operation, theHI setpoint must always be set above the LO.
In controlsafe operation, the output relaychanges state when the input current is belowthe HI setpoint or above the LO setpoint. Non-controlsafe operation is the opposite. Whenusing controlsafe mode, a loss of power causesan alarm state output.

Diagnostic LEDsThe KFDA-DCI is outfitted with three LEDs. Thefirst is a green INPUT LED which indicates DCpower and input signal status. If this LED is notilluminated upon power-up, check wiringconnections. When the input signal is over110% of the full scale range, the INPUT LEDflashes at 8 Hz; below 0% it flashes at 4 Hz.Each setpoint has its own red LED that indicatesthe relay state. An illuminated LED indicates atripped condition.

The KFD2-GS-1.2W is a trip amplifier for twoindependently field-configurable limit alarms.Three-way galvanic isolated units convert0/4-20 mA, 0/1-5 V and 0/2-10 V signals intotrip point outputs.
OperationFor high alarm indication, the status of thecontact output changes when the setpoint isexceeded and will not reset until a lowervalue is met. The difference between thesestates is the adjustable hysteresis.
The trip alarm is adjustable by a selectorswitch and potentiometer.
A monitoring voltage output of 0-10 V can beused to adjust limit values and hysteresiswithout interrupting the input signal.

2. Use potentiometers T1 or T2 to set switchpointsfor limit 1 or 2 respectively.
ExampleInput signal: 0-5 VSwitchpoint: 2.5 V
2.5 V represents 50% of the input measurement range.The voltage between terminals 5+, 3- or 6+, 3- should thenbe adjusted to 5 V (represents 50%).

2. Use potentiometers T1 or T2 to set switchpointsfor limit 1 or 2. The selected switchpoint (SP)represents y% of the input measurement range,where:
(SP - lower input value)
(upper input value - lower input value)
The limit value (LV) is calculated using the followingformula: LV = (y x 8 volts) + 2 volts
ExampleInput signal 4-20 mASwitchpoint 12 mA
y = (12 mA - 4 mA) / (20 mA - 4 mA) = 50%LV = (50% x 8 volts) + 2 voltsLV = 6 volts

OperationSetpoints can be configured as HI or LOin selectable controlsafe or non-controlsafeoperating modes. The KFDA-RTD relies ondeadband (hysteresis) and constant samplingof the input to prevent false switching when theinput varies slightly on either side of thesetpoint. The input must remain uninterruptedbeyond the setpoint for 100 ms to qualify as avalid trip condition. To return the alarm to anuntripped condition, the input signal must falloutside the deadband and remain there for 100ms. This time-based dynamic deadbandimproves setpoint stability.
For HI trip, the relay changes state when thethermocouple signal rises above the setpointvalue, and will remain in this state until the inputsignal falls below the deadband. In the case ofLO trip, when the input signal falls below thelow setpoint value, the relay changes state andremains that way until the millivolt signal climbsabove the deadband. For proper deadbandoperation the HI setpoint must always be setabove the LO.
In controlsafe operation, the output relaychanges state when the input voltage is belowthe HI setpoint or above the LO setpoint. Non-control-safe operation is the opposite. Whenusing controlsafe mode, a loss of power causesan alarm state output.
Connection Diagram
Diagnostic LEDsThe KFDA-RTD is outfitted with three LEDs.The first is a green INPUT LED which indicatesDC power and input signal status. If this LEDis not illuminated upon power-up, check wiringconnections. When the input signal is over110% of the full scale range, the INPUT LEDflashes at 8 Hz; below 0% it flashes at 4 Hz.Each setpoint has its own red LED thatindicates the relay state. An illuminated LEDindicates a tripped condition.

The loop-powered currentrepeaters are fully floatingisolators for standard 4-20mA instruments. A typicalapplication involves thedriving of I/P converters.The first application uses asingle-channel conditioner;the second uses a dual-channel version.
For the last application, avariable speed drive with a4-20 mA feedback loop isused as the input for aKFD0-CS-2.50. Note that inthis application a single inputis used to produce twooutputs. However, in such acase, a jumper must beinstalled.
A high-speed frequency drivewith a feedback loop deliversa 4-20 mA signal to the inputof the analog isolator. For aselectable analog output,use model KFDX-DCI. For0-20 mA inputs, use modelKFD2-CD-1.32-2.
In the second application, aKFDA-DCI limit alarmaccepts a 4-20 mA signalfrom a three-wire transmitterand provides two relayoutputs. Power for thetransmitter is provided by theKFDA-DCI via a 24 VDCexcitation terminal. The relayoutputs can be configured asHI and LO alarms andadjusted to trip at specificinput levels.
The last application is aconnection diagram forapplications where bothvisual indication and HI/LOalarms are required.
A high speed frequencydrive with a 0-10 Vfeedback loop is interfacedto a KFDX-DCV analogisolator that delivers ananalog signal to the meterfor visual speed indication.For 4-20 mA loop-poweredapplications, use modelKFD0-VC-1.10.
In the second application,a KFDA-DCV limit alarmaccepts a 0-10 V signalfrom a three-wire transmit-ter and provides two relayoutputs. The third wire ofthe transmitter is con-nected to a terminal thatprovides 24 VDC excita-tion. The relay outputs canbe configured as HI andLO alarms and adjusted totrip at specific input levels.
The last application shouldbe used when both visualindication and trip outputsare desired.
In the first application a drivegenerates an alternatingvoltage for feedback control.The KFDX-AC analogisolator delivers a propor-tional DC signal to themeasuring device or visualindicator.
In the remaining set ofapplications, a thermocouplemonitors the water tempera-ture. The signal conditioneraccepts the thermocouplesignal and converts it for usewith the analog temperaturemeter. For 4-20 mA loop-powered applications, usemodel KFD0-TT-1.
In the third application, alimit alarm provides anaudible alarm output and hotwater shut-off when thewater temperature reachesan unsafe level. Output A isconfigured as a HI/HI alarm;when a dangerous watertemperature is reached,relay A closes a solenoidvalve in the hot water line.Output B trips an audiblealarm warning as watertemperature approaches anunsafe level.
The last application usesboth an analog isolator and alimit alarm to provide directtemperature indication aswell as alarm trip points.
A frequency signal ismonitored for speed control.The KFDX-HZ provides aproportional DC signal to theinput frequency. Thisinformation is used for overor under-speed control orvisual indication of speed.
An RTD monitors thetemperature of a process forthe prevention of overheat-ing. In this application, aKFDX-RTD analog isolatorconverts the input signal foruse with an analog meter,providing visual indication oftemperature. For 4-20 mAloop-powered applications,use model KFD0-TR-1.
The signal conditioner in thethird application accepts theRTD signal and provides twoForm C relay outputs. OutputB is configured as a HI alarmand will trip at a customerconfigured ‘caution’ tempera-ture, activating a warningalarm. Output A is configuredas a HI/HI alarm set at thehighest temperature allowedwithout causing equipmentdamage. When this tempera-ture is reached, Output Atrips and cuts off power tothe field device.
The last application is acombination of the previoustwo applications, providinganalog temperatureindication, a visual alarm andan emergency shut-off.

Classification by Classes,Divisions and Groups
In the past, USA and Canada have relied on classification of hazardous areasby Classes, Divisions and Groups. Although this system is still in use, North Americais gradually beginning to adopt a classification system based on Zones as standardizedin IEC countries (countries accepting International Electrotechnical Commission based standards).
*North America only
Division 1: An explosive concentration of thehazardous material may be continuously, intermit-tently, or periodically present under normal operatingconditions.
Zone 0: An explosive gas-air mixture is continuouslypresent or present for long periods.Zone 1: An explosive gas-air mixture is likely to existunder normal operating conditions.
Division 2: An explosive concentration of thehazardous material is present only under faultconditions, and, if such a condition occurs, it will existonly for a short period.
Zone 2: An explosive gas-air mixture is not likely tooccur under normal operating conditions, and , if sucha condition occurs, it will exist only for a short period.
Explosive atmospheres are grouped according to theirignition capabilities.Representative atmospheres are:Group A: acetyleneGroup B: hydrogenGroup C: ethyleneGroup D: propane
Group E: metal dustGroup F: carbon dustGroup G: flour, starch, grain
