Laureate LTA Series 4-20 mA DIN rail transmitters
provide a highly-accurate, 16-bit, 4-20 mA, 0-20 mA or
0-10V isolated analog output from a wide choice of
industrial signals. |
The Laureate LTS6 serial input transmitter converts an RS232
or RS485 serial data signal to an isolated 16-bit, 4-20
mA, 0-20 mA or 0-10V analog transmitter
output. |
Model QLS Quad Output Loop Splitter / Retransmitter
sources up to four independently adjustable 4-20 mA
current outputs from a single 4-20 mA,
1-5V, 0-5V or
0-10V input. |
Inputs for 4-20 mA current transmitters can be analog inputs (AC voltage or current,
DC voltage or current,
strain gauge,
load cell,thermocouple,
RTD,
resistance), pulse inputs (rate
& frequency,
totalizing,
quadrature position or rate,
process time,
sum, difference or ratio of two inputs,
AC phase angle or power factor,
duty cycle), or
a
serial data (RS232 or RS485) input.

Laureate LTM series DIN rail transmitters
provide an isolated RS232 or RS485 serial data output
for the same wide range of industrial analog and
pulse input signals as our 4-20 mA
transmitters. |
The Modbus protocol (RTU or ASCII), as well as
our simpler Custom ASCII protocol,
are fully supported.
Easy transmitter setup is via our Windows-based
Instrument Setup Software. |
Standard features of all Laureate
transmitters include two 130 mA AC/DC solid state
relays, an isolated analog output, and isolated serial
data communications. |
Inputs for Modbus serial output transmitters
can be analog inputs (AC
voltage or current,
DC voltage or current,
strain gauge,
load cell,
thermocouple,
RTD,
resistance), or pulse input s (rate
& frequency,
totalizing,
quadrature position or rate,
process time,
sum, difference or ratio of two inputs,
AC phase angle or power factor,
duty cycle).

Model LTNET485
is a DIN-rail mounted Ethernet-to-serial device server
which interfaces the Ethernet to up to 31 Laureate
transmitters and meters on an RS485 bus. Discovery and
configuration of Ethernet |
nodes and their connected devices can be via a Console
Mode, which uses Windows-based Node Manager Software, or
via a Webserver Mode, which uses a browser to access
software resident in the node itself. |
All
Laurel transmitters come
with RS485 I/O and can be connected to the LTNET485
using 3 parallel wires (half-duplex RS485) or 5 parallel
wires (full-duplex RS485), with no need for a hub. |

Laureate digital panel metersoffer high speed and 5-digit accuracy, plus hardware options and programmable features to solve complex industrial measurement and control problems at minimum cost. |
Laureate meter options (all isolated) include
contact or solid state relays, an
analog output, and serial communications (Ethernet, USB, RS485, RS232). The Modbus protocol is fully supported. |
Meter applications include AC voltage or current,
DC voltage or current,
process (e.g., 4-20 mA),
process totalizer,
strain gauge,
load cell,
thermocouple,
RTD,
resistance, and
weighing applications. |

The loop powered 88-PRO process meter can be connected directly to a 4-20 mA, 10-50 mA or 1-5 mA current loop,
with no need for additional power to the meter. |
The M-35 Microminiature process meter is powered by isolated 10-30 Vdc power for 4-20 mA, 0-10 mA, 0-2V,
1-5V, or 0-10V process signals. |
Junior Series digital panel meters are general purpose , economical, 3-12 digit indicators for AC, DC and
process signals. |

Laureate counter / timers are applicable to a wide range of applications with pulse or AC signals. They offer exceptional accuracy with a 6-digit display at high update rates. Hardware options (all isolated) include relays for alarm or control,
analog outputs, and serial communications (Ethernet, USB, RS485, RS232).
The Modbus protocol is fully supported. |
A frequency signal conditioner board accepts two signals from 0 Hz to 1 MHz at signal levels from 12 mV to 250 Vac. Applications include rate, frequency & period, totalizing, process timing,
batch control,
phase angle and power factor, and
duty cycle. The two channels can be combined
arithmetically, for instance to display the sum, difference or ratio of two flow rates or two totalized flows. |
A voltage-to-frequency signal conditioner board converts analog signals to a frequency, thereby converting the counter into a very accurate process meter and process signal totalizer. A quadrature signal conditioner board accepts A and B encoder signals for accuratedisplay of quadrature rate or position. |
