Analog Input Transmitters, 4-20 mA or 0-10V Output:

DC voltage or current

AC rms voltage or current

Process signal (wide range of DC voltage or current signals)

Process signal totalizer (for 0-1 mA, 4-20 mA or 0-10V signals)

Thermocouple temperature (ultra-linear output for 7 thermocouple types)

RTD Temperature (ultra-linear for Pt 100, Ni 120 and Cu 10 RTDs)

Resistance in ohms (five resistance ranges from 20.000 Ω to 200.00 kΩ)

Pulse Input Transmitters, 4-20 mA or 0-10V Output:

Dual Channel Frequency (for frequency, rate, or period)
Dual Channel Pulse Input Totalizer (Rate or total. Selectable square root extraction)
Arithmetic Functions (applied to rate or total with 2 channels: A+B, A-B, AxB, A/B, A/B-1)
Duty Cycle (transmits ON or OFF period in percent of total period)
Stopwatch (timing for single events or accumulated events)
Time Interval (average time of periodic events)
Phase Angle (for angular phase offset in degrees of AC waveforms)
Quadrature (position or rate from quadrature encoder signals)

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.
