The Laureate™ 1/8 DIN Digital Panel Meter for bidirectional position, length or angle measurement
with the Standard counter main board accepts the A & B quadrature signals from shaft encoders or linear encoders to provide a highly accurate, scaled display of position, length, or angle in engineering units, such as ft, cm or degrees. The A & B quadrature signals are 90° out of phase, and their phase relationship determines whether up counts (+) or down counts (-) are counted. The meter totalizes the counts and then scales the total in software for display and control. A zero index signal, or Z signal, can be added as a third input to the A & B signals.
Bidirectional Rate Measurement
The Laureate™ quadrature meter with the Extended counter main board can be set up for scaled position or rate, but not for simultaneous position and rate. For example, it can display the speed of a moving slab in ft/sec. The display and control output update rate for position or rate is normally set to a maximum of 25/sec, as determined by a user-programmable gate time.
Quadrature Meter Capabilities One, two or four quadrature transitions may be counted at a maximum combined rate of 250 kHz and be mathematically scaled for display in engineering units from -999,999 to +999,999. Maximum pulse rates are 250 kpulses/sec at X1, 125 kpulses/sec at X2, and 62.5 kpulses/sec at X4. Single-ended input signals up to 5V or balanced line driver signals up to 10V are accommodated by the quadrature signal conditioner board. Anti-jitter circuitry eliminates errors due to vibration of the encoder. An excitation output from the meter can be used to power the encoder, thus avoiding the need for an external powr supply. Jumper selectable levels are 100 mA at 5V or 120 mA at 10V.
A zero index pulse, if available from the encoder, is interpreted by the meter as a zero reference for an integral number of revolutions of a rotary encoder, or as the home position of a linear encoder. It is used by the meter for initializing and correcting any cumulative pulse count errors. Special circuitry corrects for width of the zero index pulse. In the event of a power failure, the latest total can be stored in non-volatile memory and be used as the starting point for counting when power resumes. Power fail save or zero index capabilities are alternate meter setup choices.
Unidirectional Position and Rate
If the counts are only for one direction, for example for extrusions measured by an encoder wheel, only the encoder's "A" channel can be used and be output to an Extended Laureate totalizer. This model accommodates very high pulse rates up to 1 MHz, and unlike the quadrature meter, it can simultaneously track rate and total. It can also be programmed for batch control, which allows it to simultaneously track rate, batch (or current) total, and grand total or number of batches.
Laureate Digital Panel Meters are easily programmed with Laurel’s free Instrument Setup Software, downloadable from our website and compatible with Windows PCs, requiring a data interface board for setup.
All signal conditioner board ranges are factory-calibrated, with calibration factors for each range securely stored in an onboard EEPROM. These factors can be scaled via software to accommodate external shunts, enabling field replacement of signal conditioner boards without necessitating recalibration of the associated digital panel meter. For optimal accuracy, factory recalibration is recommended annually. All Laurel Electronics instruments undergo factory calibration using the industry-leading Fluke calibrators, which are recalibrated yearly and certified traceable to national standards, ensuring the highest level of precision and reliability.
Digital signal filtering modes can be selected to ensure stable readings in electrically noisy environments.
An unfiltered selection provides true peak and valley readings and aids in control applications.
A batch average filter selection averages each 16 conversions.
An adaptive moving average filter selection provides a choice of 8 time constants from 80 ms to 9.6 seconds. When a significant change in signal level occurs, the filter adapts by briefly switching to the shortest time to follow the change, then reverts back to its selected time constant. An Auto setting selects the time constant selection based on signal noise.
Peak and valley values are automatically captured. These may be displayed via a front panel pushbutton command or control signal at the rear connector, or be transmitted as serial data.
Two rear panel control Inputs (CMOS/TTL levels, logic 0 = tied to digital ground, logic 1 = open) or dry contacts that can be set to control / activate 14 meter commands.
An (isolated) 5, 10, 12, or 24 Vdc excitation output is standard to power transducers or two-wire transmitters. Ratiometric operation, which automatically compensates for changes in the applied excitation, is jumper selectable for applications, such as bridges, where the signal to be measured is proportional to the excitation level.
Modular Design for Maximum Flexibility at Minimum Cost
All boards are isolated from meter and power grounds. Optional Plug-in-Play boards for communications and control include Ethernet, WiFi, serial communication boards, dual or quad relay boards, and an analog output board. Laureates may be powered from 85-264 Vac or optionally from 12-32 Vac or 10-48 Vdc. The display is available with bright red or green 0.56" (14.2mm) high LED digits. The 1/8 DIN case meets NEMA 4X (IP65) specifications from the front when panel mounted. Any setup functions and front panel keys can be locked out for simplified usage and security. A built-in 5, 10, 12, or 24 Vdc excitation supply can power transducers, eliminating the need for an external power supply. All power and signal connections are via UL / VDE / CSA rated screw clamp plugs.
The Laureate™ Series features modular design with up to 7 isolated plug-in boards, applicable to all Laureate 1/8 DIN Digital Panel Meters.
Modular Hardware
The design of the Laureate™ Series is modular for maximum flexibility at minimum cost. All boards are isolated from meter and power grounds. The base configuration for a panel meter or counter consists of a main module (with computer and plug-in display boards), a power supply board, and a signal conditioner board. Optional plug-in-play boards include an isolated setpoint controller board, an isolated analog output board, and an isolated digital interface board. Modular design and a choice of plug-in options allow the Laureate to be customized for a broad range of applications from simple monitoring to control and computer interface. There can be up to five plug-in boards in a 1/8 DIN Laureate.
Connecting Laureate Digital Panel Meters to a Local Area Network (LAN)
Up to 30 Laureate Digital Panel Meters and/or LT Transmitters can be configured for RS485 and daisy-chained to an LT Transmitter using Laurel’s High Speed Ethernet-to-RS485 converter board for seamless LAN integration. Alternatively, Laurel LTE series Ethernet transmitters can connect directly to a LAN via an Ethernet cable. Setup for both configurations is streamlined using Laurel’s free Instrument Setup Software, which simplifies node discovery and transmitter configuration.
Flexible Communication Options for Digital Panel Meters
Laureate Digital Panel Meters can be equipped with Laurel communication boards to support various interfaces and protocols. These include serial interfaces with ASCII or Modbus RTU protocols, and Ethernet interfaces with web access, ASCII, or Modbus TCP/IP protocols, ensuring versatile connectivity for your commercial applications.
