These functions are applicable to rate or total after scalingto engineering units. The following are application examples:•Add two flows (A+B) for total flow or total volume.•Subtract two flows (A-B) for net flow or net volume.•Take the ratio of two flow rates (A/B) for chemical mixing.•Take the ratio of RPMs or belt speeds (A/B) to synchronizemoving machinery.•Subtract 1 from ratio (A/B-1) to control elongation of materialcompressed by rollers (draw).•Multiply belt speed by weight of material on the belt to for rateor weight of material delivered by the belt. A weighttransducer with frequency output is required.Ratio and draw are similar, except that 1 is subtracted from ratioto obtain draw. The frequency of channels A or B is measuredand converted to rate in engineering units by multiplying it by theappropriate scale factor for that channel. Either rate can bedisplayed. The A/B ratio is taken mathematically by the meter,and 1 is subtracted for draw. The result can be multiplied by amultiple or 10 from 0.0001 to 100000, and the decimal point canbe set to display the result with the desired precision up to sixdigits.Fast, High Resolution Measurements. Laureate countersdetermine frequency by timing an integral number of periods overa programmable gate time. The inverse period approach allowsgreater accuracy and faster update times than conventionalmeters which count signal pulses over a specified time interval.Channel A accepts pulses from 0.005 Hz to 1 MHz, while Chan-nel B accepts pulses from 0.005 Hz to 250 kHz. At the minimumgate time of 10 ms, update rates can be up to 25/second. Suchfast response is ideal for peak capture and for alarm and controlapplications. Variations in the displayed reading can be reducedby selecting a longer gate time. An adaptive digital filter canfurther reduce variations due to noise while rapidly responding toactual changes in the signal.Universal Signal Conditioner. The Laureate dual-channelsignal conditioner accepts inputs from proximity switches withPNP or NPN output, TTL or CMOS logic, magnetic pickups,contact closures, low-level outputs from turbine flow meters downto 12 mV, or high-level AC line inputs to 250 Vac. Jumper selec-tions provide optimum operation for different sensor types andnoise conditions. A built-in isolated 5, 10, or 24 Vdc excitationsupply can power proximity switches or other sensors, andeliminate the need for an external power supply.Designed for system use. Optional plug-in boards includeEthernet and other serial communication boards, dual or quadrelay boards, and an isolated analog output board. Laureatesmay be powered from 85-264 Vac or optionally from 12-32 Vacor 10-48 Vdc. The display is available with red or green LEDs.The 1/8 DIN case meets NEMA 4X (IP65) specifications from thefront when panel mounted. Any setup functions and front panelkeys can be locked out for simplified usage and security. A built-in isolated 5, 10, or 24 Vdc excitation supply can power trans-ducers and eliminate the need for an external power supply.All power and signal connections are via UL / VDE / CSA ratedscrew clamp plugs.SpecificationsDisplayReadout Display Range Zero Adjust Span Adjust Indicators 6 LED digits, 7-segment, 14.2 mm (.56"), red or green LED -999999 to +999999, XXXXEX notation beyond 999999-999999 to +9999990 to 999999Four LED lampsInputsTypesSignal Ground Channel A Frequency Channel B Frequency Minimum Signal Maximum Signal Noise FilterContact Debounce AC, pulses from NPN, PNP transistors, contact closures, magnetic pickups Common ground for channels A & B0.005 Hz to 1 MHz0.005 Hz to 250 kHzNine ranges from (-12 to +12 mV) to (+1.25 to +2.1V)250 Vac1 MHz, 30 kHz, 250 Hz (selectable)0, 3, 50 ms (selectable)Rate AccuracyTime Base Span Tempco Long-term Drift Crystal calibrated to ±2 ppm ±1 ppm/°C (typ)5 ppm/yearPowerVoltage, standard Voltage, optional Power frequency Power consumption (typical, base meter) Power isolation 85-264 Vac or 90-300 Vdc12-32 Vac or 10-48 VdcDC or 47-63 Hz1.2W @ 120 Vac, 1.5W @ 240 Vac, 1.3W @ 10 Vdc, 1.4W @ 20 Vdc, 1.55W @ 30 Vdc, 1.8W @ 40 Vdc,2.15W @ 48 Vdc250V rms working, 2.3 kV rms per 1 min testExcitation Output (standard)5 Vdc10 Vdc24 VdcOutput Isolation 5 Vdc ± 5%, 100 mA10 Vdc ± 5%, 120 mA 24 Vdc ± 5%, 50 mA50 Vdc to meter groundAnalog Output (optional)Output Levels Current compliance Voltage compliance Scaling Resolution Isolation 4-20 mA, 0-20 mA, 0-10V, -10 to +10V (single-output option) 4-20 mA, 0-20 mA, 0-10V (dual-output option)2 mA at 10V ( > 5 kΩ load)12V at 20 mA ( < 600Ω load)Zero and full scale adjustable from -99999 to +9999916 bits (0.0015% of full scale)250V rms working, 2.3 kV rms per 1 min test(dual analog outputs share the same ground)Relay Outputs (optional)Relay Types Current Ratings Output common Isolation 2 Form C contact relays or 4 Form A contact relays (NO)2 or 4 Form A, AC/DC solid state relays (NO)8A at 250 Vac or 24 Vdc for contact relays120 mA at 140 Vac or 180 Vdc for solid state relays Isolated commons for dual relays or each pair of quad relays 250V rms working, 2.3 kV rms per 1 min testSerial Data I/O (optional)Board Selections ProtocolsData Rates Digital Addresses Isolation Ethernet, Ethernet-to-RS485 converter, USB, USB-to-RS485 converter, RS485 (dual RJ11), RS485 Modbus (dual RJ45), RS232.Modbus RTU, Modbus ASCII, Laurel ASCII protocol300 to 19200 baud247 (Modbus), 31 (Laurel ASCII),250V rms working, 2.3 kV rms per 1 min testEnvironmental Operating Temp.

The sensing element is normally a turbine flowmeter, which outputs pulses at a frequency proportional to flow rate. The A/B ratio can also be displayed for totalized rate (or delivered volume). Comparing Fluid Inflow & OutflowThe ratio of the inflow and outflow rates of a tank is a measure of the relative filling or emptying rate. The same meter can also be programmed to display the net inflow or outflow rate in flow units, or to display totalized inflow our outflow in volume units. Any of these parameters can be alarmed using the dual relay board and be transmitted via 4-20 mA, RS-232 or RS-485. Controlling Coating Thickness on a FilmIn this application, Channel A measures the rate at which a coating material is applied, as measured by a flow meter, while Channel B measures the speed of the film based on pulses from a proximity switch. Displaying and alarming the A/B ratio assures that an even thickness of coating material is applied as the speed of the film is varies. Synchronizing Two Conveyor LinesThe dual-channel Laureate counter can measure the speed of conveyor lines by using the output of proximity switches which sense gear teeth or spokes of rotating drive wheels. Displaying the speed ratio of two lines allows line speeds to be adjusted so that material arrives at work stations when needed. Measuring Draw for ElongationDraw (Ch A / Ch B - 1) can be used to display the elongation of films compressed between rollers, the shrinkage films, and the RPM difference of rollers whose speed is varied to maintain tension. The six-digit resolution of the Laureate dual channel counter / rate meter is ideal for comparison of rates that are close to each other.Ordering GuideCreate a model number in this format: L70000FR, IPCMain Board L7 Extended Main Board, Green LEDsL8 Extended Main Board, Red LEDsNote: Extended capability is required for arithmetic functions, simultaneous rate and total in thesame counter, phase, stopwatch, batching, and custom curve linearization.Power0 Isolated 85-264 Vac1 Isolated 12-32 Vac or 10-48 VdcRelay Output (isolated) 0 None1 Two 8A Contact Relays2 Two 120 mA Solid State Relays3 Four 8A Contact Relays4 Four 120 mA Solid State RelaysAnalog Output (isolated) 0 None1 Single isolated 4-20 mA, 0-20 mA, 0-10 V, -10 to +10V2 Dual isolated 4-20 mA, 0-20 mA, 0-10VDigital Interface (isolated) 0 None1 RS-2322 RS485 (dual RJ11 connectors)4 RS485 Modbus (dual RJ45 connectors)5 USB6 USB-to-RS485 converter7 Ethernet8 Ethernet-to-RS485 converterInput Type FR Dual-Channel Pulse Input Signal ConditionerAdd-on Options CBL01RJ11-to-DB9 cable.

It can measure true RMS voltage or current of ACsignals where there is considerable distortion of the waveform,such as rectifier outputs or waveforms chopped by an SCR,TRIAC or transistor circuit, as illustrated.•True RMS readings in 0-16 ms after completion of one inputsignal cycle allow anomalies to be detected and alarmedbefore they become expensive problems. Fast on/off controland alarm can be achieved with optional dual or quad relays,either contact or solid state. The meter can also capture peakand valley readings that occur at 50/60 Hz.•Accuracy is 0.1% of full scale for signals from DC to 10 kHzand signal amplitudes down to 0.1% of full scale. The crestfactor (Vp / Vrms) is 3.0 at full-scale Vrms of 20,000 countsand a Vp of 60,000 counts. The meter starts to flashoverrange at 132% of full scale Vrms , at which point theavailable crest factor is 60,000 / 26,400 = 2.27. Meaningfulreadings with rated resolution continue to be obtained up to212% of full scale Vrms (42,433 counts) for sinusoidal signals,at which point the available crest factor is 1.414. For safetyreasons, the maximum RMS input signal should never exceed600V or 5A. ETL certification is for a maximum voltage of 300Vrms.AC or DC coupling is jumper selectable on the signal condition-er board. AC coupling accommodates signals from 10 Hz to 10kHz and is suitable for applications such as measuring AC rippleon a DC power supply. DC coupling accommodates signals from0 to 10 kHz. Multiple integral cycles are averaged for signalsabove 50/60 Hz. A single cycle is captured for signals from 3 Hzto 50/60 Hz. Below 3 Hz and at DC, thecapture rate is 3/sec.Use with current Transformers. Highcommon mode rejection allows stablereadings with current shunts located onthe high side of the line. Five amp inputcapability allows the output of 5A currenttransformers to be applied directly to themeter, with no need for a stepdowntransformer. The meter reading can easily be scaled for thecurrent transformer ratio. Digital filtering is selectable for noisysignals.Designed for system use. Optional plug-in boards includeEthernet and other serial communication boards, dual or quadrelay boards, and an isolated analog output board. Laureatesmay be powered from 85-264 Vac or optionally from 12-32 Vacor 10-48 Vdc. The display is available with red or green LEDs.The 1/8 DIN case meets NEMA 4X (IP65) specifications from thefront when panel mounted. Any setup functions and front panelkeys can be locked out for simplified usage and security.

Laureate meters and counters are low-cost means to instrument and alarm AC power lines withgreat accuracy:•AC RMS Voltmeter and Ammeter. True RMS capability allows the display of RMS voltage for non-sinusoidal waveshapes, such as square waves from a UPS. A built-in 5 A range can be used to displaycurrents up to 5.000 A with 1 mA resolution or accept the output of 5 A current transformers. The200.00 mV range can be used with external current shunts. With either transformers or shunts, scalingof the input current is easily accomplished via the meter's front panel pushbutton switches.•Frequency Meter. Inverse period is used to determine AC line frequency to six-figure accuracy(60.0000 or 50.0000) in a few line cycles plus 30 ms.•Phase Angle & Power Factor Meter. Two signals with identical periods are applied to Channels Aand B. A phase angle resolution of 1°, 0.1° or 0.01° is selectable.
