LTA
Series 4-20
mA, 0-20 mA & 0-10V
Analog Output
DIN Rail Transmitters
DIN Rail mounted, digitally
programmable.
Exceptional accuracy at high update rates.

Models by Input
Signal:
Loop Splitters:
- QLS Quad Loop Splitter. Splits on
analog input into up to four independently scalable 4-20 mA output
loops. Outputs can share the same ground.
- TLSA Triple Loop Splitter. Splits one
analog input into up to three independently scalable 4-20 mA output
loops. Outputs cannot share the same ground. Replaced by QLS for new
applications.

Three analog outputs are
jumper selectable: 4-20 mA, 0-20 mA or 0-10V. All selections provide
16-bit (0.0015%) resolution of output span and 0.02% output accuracy. Output isolation from signal and power grounds
eliminates potential ground loop problems.
Fast read rate at up to 50
or 60 conversions per second while integrating the signal over a
full power line cycle is provided by Concurrent Slope (Pat 5,262,780)
analog-to-digital conversion for analog input signals. High read
rate is ideal for peak or valley capture and for real-time computer interface and control. Digital
signal filtering modes are selectable
for stable readings in electrically noisy environments. The internal digital readings
and analog output can be individually selected to be either unfiltered or filtered.
Easy Transmitter programming is via
Laurel's Instrument Setup Software,
which runs on a PC under MS Windows. This software can be downloaded from this website at no charge. The required transmitter-to-PC interface cable is available from
Laurel (P/N CBL04).
Laureate
LTA Series 4-20 mA output
transmitters duplicate the performance and extensive programmable
features of their Laureate digital panel meter, counter and timer
counterparts. This allows unique configurations, such as 4-20 mA transmitter
versions of pulse totalizers,
analog totalizers, or quadrature position meters. A unique product is
Laurel's TS6 serial-to-analog
converter transmitter, which converts serial data to an isolated analog
output.
