Model 10A69-4 Four Channel AC RMS Input Card
accurately measures the true RMS amplitude up to four independent external analog AC signals, mixed as desired, from a wide range of voltage sources. Since the 10A69-4 does not provide excitation, the voltage 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 three millivolt ranges (50, 100, and 200 mV-AC) are intended primarily for current measurement by means of an external shunt.
The Model 10A69-4 will accept Transducer Types: AC signal sources (voltage only) Input Voltage and Current Ranges: 50 mV to 200 VAC; automatically selected—on an individual channel basis—when the channel is configured.
