MLT-P | 4-20 mA & Serial Data Output | Process & Ration Signals | DIN Rail Transmitter

The Micron Meters 4-20 mA and RS232/RS485 output, process signal input transmitter provides zero and span adjustment for use with a wide range of industrial transducers. Six DC voltage and four DC current input ranges are jumper selectable. The two most sensitive voltage ranges, 200.00 mV and 2.0000V, provide a high input impedance of 1 GΩ to minimize the load on the voltage signal.

The transmitter can be set to a ratio mode (or potentiometer follower mode) by making selections at the connector and in software. In this mode, the transmitter output tracks a ratio of the applied excitation voltage and is unaffected by changes in the excitation voltage. This capability is used for resistive bridge sensors and voltage dividers, such as potentiometers which track wiper position. Ratiometric measurements provide an exceptional accuracy of 0.01% of reading ± 2 counts.

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

Standard features of Micron LT transmitters include:

  • 4-20 mA, 0-10V or -10V to +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.
  • Serial communications output, RS232 or RS485 (half or full duplex), jumper selectable. Three protocols are user selectable: Modbus RTU, Modbus ASCII, or Custom ASCII. Modbus operation is fully compliant with Modbus Over Serial Line Specification V1.0 (2002). The Custom ASCII protocol is simpler than the Modbus protocol and is recommended when all devices are Micron units.
  • Dual solid state relays, isolated, for alarm or control. Rated 120 mA at 140 Vac or 180 Vdc.
  • Transducer excitation output, isolated. User selectable 5V@100 mA, 10V@120 mA or 24V@50 mA.
  • Universal 85-264 Vac power. Low-voltage 10-48 Vdc or 12-32 Vac power is optional.

Easy Transmitter programming is via the 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. (P/N CBL04).
