8412

8ch ADC+Tacho, IEPE, Direct

Overview

This card is ideal for situations where higher sampling rates are not required, but high quality, repeatable, high resolution data captures are desired. Although the 8412 has a slightly lower specification than the 8402 it provides twice the channel density. This allows for example a P8020 chassis to support a total of 40 analog channels with two tacho channels. This card is used primarily in situations where high channel counts are required.
