MECO MFM-96 with MODBUS RTU Protocol

MFM-96 is a New Multifunction Power and Energy Monitor indigenously designed, tooled and manufactured by the Research and Development Department of MECO. This 96x96mm micro-controller based meter indicates TRMS values of more than 60 electrical parameters displayed on 21 display pages. Four rows of 4 digit LED displays provide good measuring resolution for any parameter. It is available in 3Phase 3Wire 2Element (3P3W2E) and 3Phase 4Wire 3Element (3P4W3E) configurations. The 4 keys on the front panel of the meter can be used to scroll through display pages and to program CTR, PTR & Instrument Address. It has built in isolated RS 485 (MODBUS) port that can be interfaced to the PC through a twisted pair bi-polar screened cable. Upto 256 such MFM-96’s can be connected in cascade on the same line at a time for upto 4000 feet distance.

The MFM-96 is supplied with MECO Power Master PC interface software which is ideal for remote monitoring and storage of the measuring parameters on the PC. The parameters can be grouped into tables or graphs for analysis and management of any electrical system. The software has various feature like real time display, tabular representation and graphical display of measured and stored values, history trends, alarms for Max./Min. values etc. These values can be converted to Excel format for further data processing and import into other software platforms.
