MLTE-RM DIN Rail Transmitter | AC RMS Voltage or Current Input

MLTE-RM | Ethernet & 4-20 mA Output | AC RMS Voltage or Current | DIN Rail Transmitter

The Micron Meters  AC RMS input transmitter provides six voltage input ranges and four current input ranges, all factory calibrated and jumper selectable. A special 5.000A range utilizes a built-in 0.01 ohm shunt resistor to accept the output of 5A current transformers, with no need for a stepdown transformer. The current readings can be scaled digitally as needed. High common mode rejection allows stable readings with current shunts located on the high side of the line. Digital filtering is selectable for noisy signals.

LT transmitter AC

True RMS precision circuitry is used to determine the root-mean-square of complex waveforms from DC to 10 kHz. Spikes up to 3.0 times the maximum of each range are accurately measured.

Accuracy is 0.03% of full scale for the transmitters with 1 Megohm input resistance, signals from DC to 10 kHz, and signal amplitude down to 0. The crest factor (Vp / Vrms) is 3.0 at full scale, increasing to 300 for a signal amplitude of 1% of full scale. A version with 10 Megohm input resistance is available as a factory special, but decreases the maximum frequency from 10 kHz to 1 kHz for three of the voltage ranges.

True RMS readings in as little as one 50/60 Hz AC line cycle are unmatched in the industry. Such a high read rate allows anomalies to be detected and alarmed before they become expensive problems. On/off control and alarm can be achieved dual solid state relays, which are standard. Transmitter can also capture peak and valley for times as short as one 50/60 Hz AC power line cycle.

Standard features of Micron MLTE transmitters and signal conditioners include:

  • Ethernet I/O, isolated. Supported protocols are Modbus RTU and ASCII (tunneled via Modbus TCP) and Custom ASCII. The latter is simpler than the Modbus protocol and is recommended when all devices are Micron units. Note that RS232 or RS485 data I/O in lieu of Ethernet is provided by MLT Series transmitters.
  • 4-20 mA, 0-20 mA or 0-10V analog transmitter output, isolated, jumper-selectable and user scalable. All selections provide 16-bit (0.0015%) resolution of output span and 0.02% output accuracy of a reading from -99,999 to +99,999 counts that is also transmitted digitally. 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.
  • Dual solid state relays, isolated. Available for local alarm or control. Rated 120 mA at 130 Vac or 180 Vdc.
  • Universal 85-264 Vac power. Low-voltage 10-48 Vdc or 12-32 Vac power is optional.
  • AC or DC coupling is jumper selectable. AC coupling is suitable for applications such as measuring the ripple on a DC power supply. Multiple integral cycles are averaged for signals above 50/60 Hz. A single cycle is captured for signals from 3 Hz to 50/60 Hz. Below 3 Hz and at DC, the capture rate is every 333 ms.

Discovery and configuration of the Ethernet Nodes is easily achieved with the Node Manager Software, and the discovered transmitters can then be programmed using the Instrument Setup Software. Both software's run on a PC under MS Windows and can be downloaded from this website at no charge.
