Electrical variablesDigital ALMEMO® D6 measuring module for AC voltage and AC current For acquiring the true root mean square (RMS) value of a sinusoidal AC signal. Sampling rate of 1000 mops. Overvoltage proof measuring input. Galvanically isolated up to 6 kV. For connection to all ALMEMO® V6 / V7 measuring instruments Applications ALMEMO® D6 measuring modules can be used for a wide variety of applications. Examples: • Inexpensive monitoring of several AC voltage signals with a large number of measuring modules • Monitoring the supply voltage and the current consumption of machines, motors, and other consumers. • Checking switches. • Monitoring of the electrical parameters voltage, in addition to the physical measured variables such as temperature, pressure, air flow, flow rate, etc. • Voltage and / or current measurement of 1-phase user (230 V AC) through a touch-proof Schuko-socket outlet adapter (accessory). The digital ALMEMO® D6 measuring module uses its own integrated AD converter. The overall accuracy of the measurement is independent from the ALMEMO® display unit/ data logger. The AC signal with sinusoidal curve progression is digitalized at the integrated AD converter at a high sampling rate and based on that, the true RMS value will be calculated continuously. At the same time, the frequency of the AC signal will be determined. The measured values are digitally interrogated by the ALMEMO® measuring device at the conversion rate of the measuring device. The ALMEMO® measuring instrument saves the measured values and the measuring software WinControl will display them graphically. The measuring input is overvoltage proof and galvanically isolated from the ALMEMO® measuring device. 11/2025 • We reserve the right to make technical changes.
