Product Description
The MCM-V module provides an isolated, three channel measurement and scaling interfaced for AC voltage measurements. It features primarily features RS-485 (Modbus/RTU) communications for accurate (better than 0.1%) and convenient measurement of three-phase (or three single-phase) circuits. In addition, it provides an isolated, scaled AC voltage output, which can be used be multiple outputs option proportional to the input signal.
The Modbus interface includes measurement of Voltage (line-to-neutral in addition to line-to-line), phase angle measurement, and frequency measurement. The data is available in both 16-bit integer, as well as 32-bit floating point measurements. PT ratios may be entered to automatically scale the readings.
In addition to its own, convenient register map, the MCM-V shares the WattsOn-Mark II register map, making it an easy addition to any system that supports the WattsOn-Mark II.
High input bandwidth and linearity ensure that all relevant harmonics of the measurement signal are captured.
