4ch ADC+Tacho, IEPE, Direct, Bridge


The 8X04 is an ultra-flexible general purpose acquisition card. It encapsulates Prosig’s 30-years of test and measurement experience and is the only card you’ll ever need! The 8404 has all the functionally and full specification of the 8X02 card. But additionally each channel includes bridge completion configurations of ¼, ½ and full bridge, internal calibration shunt resistors and selectable bridge resistance configurations of 120, 350 or 1000Ω. Further each channel provides program selectable supply voltage for transducer excitation.
