Description |
| The
Laureate™ Remote Displays accept RS-232 or RS-485 inputs
from computers, programmable controllers, Laureate meters
or Laureate counters. They blend in with the other Laureate
products and provide a visual display from -999,999
to +999,999. They can also provide remote alarm and
analog output capabilities.
The display consists of six 14.2 mm (.56") high
LED digits, available in red or green. The 1/8 DIN front
panel is environmentally sealed to NEMA-4X when panel
mounted. Standard features include input power from
85-264 Vac or 90-370 Vdc. Low voltage input power from
8-28 Vac or 9-37 Vdc is optional.
Interface to Computer or PLC
All Laureate meters and counters
allow the display of the sending unit to be duplicated
by a remote display
The simultaneous display of multiple parameters using
multiple remote displays is possible if the sending
unit is a Laureate counter equipped with an FR (frequency)
or VF (voltage-to-frequency) signal conditioner board.
The sending unit may be set up to display any of up
to four parameters: Item #1, Item #2, Item #3 or peak.
These four parameters are transmitted in sequence, and
a remote display can be set up to display any one item
in that sequence
One possibility is to install up to three remote displays
in the same control panel as the main Laureate counter
to augment its single display. For example, a Batch
Controller can show the batch total. The remote displays
can show rate, peak rate, and either grand total or
number of batches. A yellow indicator light shows which
item in the transmitted sequence has been chosen for
display.
Isolated Analog
Output Option
A Laureate remote display can
be equipped with an optional isolated analog output
board with 0-10 V and 0-20 mA outputs to serve as a
very low cost, 12-bit digital-to-analog converter. Either
output can be scaled to the displayed value. With this
board, the remote display can drive a chart recorder
or serve as a highly accurate, isolated 4-20 mA transmitter.
Alarm & Setpoint
Control Options
Each Laureate remote display can
also be equipped with an output board with dual contact
relays or dual optoisolated AC/DC solid state relays
to provide remote alarm and setpoint control capability
The relays can respond to the data values transmitted
via RS-232/485. The setpoints can be programmed locally
from the front panel of the remote display or remotely
via RS-232/485.
The relays can respond to any of eight control characters
transmitted via RS-232/485. These characters can be
transmitted by a Laureate meter or counter, thereby
assuring that the local and remote alarm points are
identical.
With the addition of the scaled analog output and alarm/setpoint
capabilities, Laureate remote displays can become significant
components of any supervisory monitoring and control
system.

Remote
Displays Augmenting a Laureate Counter |
|
The
display of a Laureate counter can be augmented by up to
three local displays to show up to four parameters
simultaneously: Items #1, #2, #3 and peak rate (if rate
was one of the selected items). All four parameters can
also be displayed at a remote location.
