LAUREATE™ Series
Hardware Overview
Modular Hardware
The design of the Laureate™ Series is modular for maximum flexibility at minimum cost.
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 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
fully-loaded Laureate.
Main Module
The main module (with
computer and display boards) defines the Laureate series (DPM, weight meter, counter, or
remote display), version (standard or extended), and LED display color (red or green). The
number of digits is 5 for DPMs or 6 for counters, weight meters and remote displays.
Digits are a full 14.2 mm (0.56") high.
Power
Supply Boards
The same standard
switching power supply board handles inputs of 95-240 Vac ±10% for worldwide AC use, plus 90-300 Vdc
(high voltage DC operation not UL approved). An optional low voltage
power supply board handles 12-30 Vac or 10-48 Vdc, allowing the meter to be powered by
batteries. Isolated 5, 10 or 24 Vdc transducer excitation output is standard with either
supply.
Signal Conditioner Boards
Four input boards
are used for DPMs:
- DC (volts, amps, mV, mA, process such as 4-20 mA, strain, pot follower).
- AC True RMS (AC volts, mV, amps, mA).
- Temperature (J, K, T, E, N, R, S thermocouple, Pt 100 ohm RTD).
- Load cell (load cells, scale meter, strain gauges, microvolts).
Three input boards are used for counters:
dual-channel counter, voltage-to-frequency, and quadrature. Click on each
link below to be linked to the
appropriate page.
Dual-channel counter:
- AC
frequency, period, rate
(includes
square root extraction and custom curve linearization)
- Digital
stopwatch
- Time interval
meter
- Phase angle
meter
- Duty cycle meter
- Up / down totalizer
(includes square
root extraction and custom curve linearization)
- Ratio, draw,
channels A+B, A-B, AxB, A/B, A/B-1
(arithmetic operation on dual input channels A & B)
-
Pulse input batch
controller
- Voltage-to-Frequency Converter
(rate, rate and total, square root, analog totalizer, analog
batch control, 1/rate (time), custom curves)
- Quadrature
Meter / Controller
(position or rate from quadrature encoders with
low-level differential or single ended logic level outputs)
Setpoint
Controller Boards
Two isolated setpoint
controller options are available to add control and alarm capability to DPMs, counters and
remote displays:
Analog Output
Board
An optional isolated analog
output board is available to provide 0-10 Vdc and 4-20 mA outputs for DPMs, counters and
remote displays. It is ideal to drive a chart recorder or for transmission to a control
room. The two outputs are linearized and independently scaled to the display. In the pulse
input batch controller, a 8A relays fill the socket of the analog output board.
Digital
Interface Boards
Optional isolated interface
boards allow the Laureate to communicate with a computer or PLC. The two serial boards
allow the Laureate to drive a remote display, or to serve as a remote display.
Designed for Industrial
Use
All Laureates are housed in a
compact and rugged 1/8 DIN case
which fits in a standard 45 x
92 mm panel cutout and requires only 102 mm (4.0") behind the panel (plus
connectors). In many applications, a Laureate can replace a larger, more expensive
instrument. The Laureate case is sealed to NEMA-4X
(IP-65) requirements from the front when panel mounted to allow high-pressure wash-down.
Connectors Included
All power and signal connections are via UL /
IEC / CSA rated screw-clamp terminals, which are standard. The RS-232 and RS-485 options
are connected via RJ-11 phone jacks.
Easy
Setup & Calibration
All Laureate meters and
counters are shipped fully configured, calibrated, and ready to run. All
ranges of Laureate DC, AC and temperature meters are calibrated at the
factory, with calibration factors stored in EEPROM. This allows different
ranges to be selected via plug-in jumpers, with no need to recalibrate the
meter for each new range.
Setup can be from the front panel or by using
powerful and easy-to-use Laureate Setup & Calibration Software, which can
be downloaded at no charge from our
Software Download Page. It can simplify setup whether
the PC is connected to the instrument or not. Absolute calibration of
Laureate panel meters requires temporary connection to an external
calibrator and to a PC running Laureate
Setup & Calibration Software. System-level scale and offset calibration can also be from
the front panel to produce specified readings from known signals, such as
4-20 mA = 0.00% to 100.00%.
Laureate Datalogging
Software
Datalogging Software
turns a
PC connected to up to 31 Laureate instruments into a powerful, low-cost
datalogging system. The Laureates can be any mix
of digital panel meters and counters, excluding only remote displays. Data can be displayed
on a computer screen in the form of up to 64 simulated panel meters, which
can include virtual meters that show an arithmetic combination of meter
readings or totalized readings, such as volume from flow rate. Data is can
be captured on disk in the form of comma-delimited ASCII files for analysis
and graphic by an external program such as MS Excel.
