The Laureate™ Remote Displays accept RS-232, RS-485, or Modbus inputs from computers, programmable controllers, Laureate meters or Laureate counters. They blend in with 1/8 DIN Laureate digital panel meters, counters and timers to provide a numeric 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 case is environmentally sealed to NEMA-4X from the front when panel mounted. Standard features include input power from 95-240 Vac ±10% or 90-300 Vdc. Low voltage input power from 12-30 Vac or 10-48 Vdc is optional.

Interface to a Computer or PLC

Multiple Laureate remote displays can be connected in parallel to a single data line in multidrop fashion and be addressed from a single data port, thereby minimizing wiring. Each unit will only display the value transmitted for its unique address. The recognition character preceding the address is programmable. The data rate is selectable from 300 to 19,200 bps.

With the RS-485 interface, up to 31 remote displays can be individually addressed and be connected in parallel. With the RS-232 interface, only 5 remote displays can be connected in parallel for impedance reasons.

Interface to Laureates

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 low cost, 12-bit (4096 step) 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 a relay 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.
