Series Hardware Overview
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
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.
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")
The same standard switching power supply board
handles inputs of 85-264 Vac for worldwide AC use, plus 90-370
Vdc. An optional low voltage power supply board handles 8-28 Vac
and 9-37 Vdc, allowing the meter to be powered by batteries. Isolated
5, 10 or 24 Vdc transducer excitation output is standard with
85 to 264 Vac and 90 to 370 Vdc
8 to 28 Vac and 9 to 27 Vdc
Four input boards available for DPMs:
DC (volts, amps, mV, mA, process such
as 4-20 mA, strain, pot follower).
(J, K, T, E, N, R, S thermocouple, Pt 100 ohm RTD).
True RMS (AC volts, mV, amps, mA).
Load cell (load cells, scale
meter, strain gauges, microvolts).
Three input boards are available for counters:
counter: AC frequency, period, rate, time interval, stopwatch,
phase angle, duty cycle, square root, up/down total, ratio or
draw, A+B, A-B, AxB, A/B, batch control, custom curves.
Voltage-to-Frequency: rate, rate and total, square root,
integrating totalizer, batch control, 1/rate (time), custom curves.
Quadrature: position or rate
from encoders with low-level differential or single ended logic
Setpoint Controller Boards
Two isolated setpoint controller options are
available to add control and alarm capability to DPMs, counters
and remote displays:
Dual 10 A relays
open collector transistor outputs
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 10A relays fill the socket of the analog output
0-10 Vdc and
0-20 mA analog output
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.
for Industrial Installation
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
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 an RJ-11 phone jack. The BCD option
uses a 30-pin, 0.1" mass termination ribbon cable connector.
