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 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 either supply.

         85 to 264 Vac and 90 to 370 Vdc

         8 to 28 Vac and 9 to 27 Vdc

Signal Conditioner Boards

Four input boards available for DPMs:

         DC (volts, amps, mV, mA, process such as 4-20 mA, strain, pot follower).

         Temperature (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:

         Dual-channel 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 level outputs.

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

         Dual isolated open collector transistor outputs

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 10A relays fill the socket of the analog output board.

         0-10 Vdc and 0-20 mA analog output

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.

         Isolated RS-232

         Isolated RS-485

         Isolated, parallel BCD output

Designed 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 high-pressure washdown.

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 an RJ-11 phone jack. The BCD option uses a 30-pin, 0.1" mass termination ribbon cable connector.
