Description
2 analog voltage inputsElectrically isolated analog channelsElectrically isolated sensor supplies16-bit digital converter resolutionVery high sampling rateNetTime timestamp: Moment of measurement
The module is equipped with 2 voltage measurement inputs with 16-bit digital converter resolution.Each voltage input has its own sensor supply. The two channels with their respective sensor supplies are electrically isolated from each other.
