Model LTE42P includes:
Model LTE42P by Laurel Electronics is a 4-20 mA process input = 0-100.00 output, Ethernet I/O plus 4-20 mA or 0-10V analog output and dual relays. DIN rail transmitter. Model is configured for Extended main board and Power over Ethernet.
The Laureate process transmitter provides six voltage input ranges and four current input ranges, all factory calibrated and jumper selectable. The 200.00 mV and 2.0000 V ranges provide a high input impedance of 1 Gohm to minimize the load on the voltage signal. A 5.000A range measures the IR drop across a built-in 10 mW current shunt. The transmitters can also easily 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 provided by Concurrent Slope (Pat 5,262,780) analog-to-digital conversion. 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.
The Extended version of process transmitters allows linearization of non-linear inputs.
Three analog transmitter output settings 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. The output tracks the reading from -99,999 to +99,999 counts that would be transmitted digitally. For DC signals, this reading has a rated accuracy of ±0.01% of full scale input and can be scaled in software. Output isolation from signal and power grounds eliminates potential ground loop problems. The supply can drive 20 mA into a 500 ohm (or lower) load for 10V compliance, or 10V into a 5K ohm (or higher) load for 2 mA compliance.
