LT2 DCA/DCV-to-4-20mA Series*

The Laurel Electronics LT2 DC Current and DC Voltage transmitter provides four current input ranges and six voltage input ranges, all factory calibrated and jumper selectable. The 200.00 mV and 2.0000 V ranges provide a high input impedance of 1 GΩ to minimize the load on the voltage signal. A 5.000A range measures the IR drop across a built-in 10 mΩ current shunt. The transmitters can be scaled in software for use with external shunts.

Fast read rate at up to 50 or 60 conversions per second while integrating the signal over a full power line cycle 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.

An unfiltered selection provides true peak and valley readings and aids in control applications. A batch average filter selection averages each 16 conversions for an update every 1/4 sec. An adaptive moving average filter selection provides a choice of 8 time constants from 80 ms to 9.6 s. When a significant change in signal level occurs, the filter adapts by briefly switching to the shortest time to follow the change, then reverts back to its selected time constant. An Auto setting selects the time constant selection based on signal noise.
