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.
