MLT-DC | 4-20 mA & Serial Data Output | DC Voltage or Current | DIN Rail Transmitter

Micron Meters DC input transmitters 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 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.

Standard features of Micron MLT 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 Transmitters or Digital Panel Meters.
• Dual solid state relays, isolated, for alarm or control. Rated 120 mA at 130 Vac or 170 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  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).
