Model 10A68-2 Dual Channel AC RMS Card
accurately measures the true RMS amplitude of one or two independent external analog AC signals, mixed as desired, from a wide range of voltage or current sources—including engineering parameters conditioned by other Daytronic cards.
Since the 10A68-2 does not provide excitation, the analog source must supply its own power supply, if required (as is the case with many accelerometers, when used to measure the noise level or vibration factor of a dynamic process). The card is particularly useful in evaluating the efficiency of AC electrical power systems. The Model 10A68-2 accepts Transducer Types: AC signal sources (voltage or current) with Input Voltage or Current Ranges from 50 mV to 500 VAC or 50 mA to 5A; automatically selected—on an individual channel basis—when the channel is configured.
