Description
Laureate 4-20 mA output
transmitters are housed in a DIN rail case that is only
22.5 mm (0.89") thick. Signal connections are via detachable
screw terminal connectors. The transmitters duplicate the
performance and extensive programmable features of their
Laureate digital panel meter, counter and timer counterparts.
Features include exceptional accuracy at high read rate,
and optional dual solid state relays for local alarm or
control.
In addition to the 4-20 mA output
that would typically be used for signal transmission in
an industrial environment, a 0-10V analog output is selectable.
Either selection provides 12-bit (4096 step) resolution
of the output span, which is ultra-linear to well within
one bit. The output tracks the linearized digital reading
that would be transmitted digitally. This reading can
be scaled in software so that its resolution far exceeds
output resolution. As a result, rated transmitter output
accuracy is ±0.05% of span for all signal types, except
for AC rms, where accuracy is ±0.1%.
Output isolation from signal and power grounds is provided
by a separate on-board power supply, which can drive 20
mA into a 600 ohm load for 12V compliance. Output isolation
eliminates problems caused by ground loops.
Laureate 4-20 mA transmitters
are available with the same signal conditioners applicable
to Laureate digital panel meters, counters and timers.
This allows unique configurations, such as 4-20 mA transmitter
versions of pulse totalizers, analog totalizers, or quadrature
position meters. All transmitter configurations related
to counters come with a special three-terminal screw connector
for two control signals plus ground.
Transmitter programming is via a
three-terminal RS-232 port using Laurel's PC-based Instrument Setup Software. This software can be downloaded from this website at
no charge. The required transmitter-to-PC interface cable
is available from Laurel (P/N CBL03).
