The DNA-AI-224 and DNR-AI-224 are high speed, four channel strain gage input boards for UEI's data acquisition and control Cubes and RACKtangle™ Chassis respectively. Suitable for use in a wide variety of applications, these boards provide an ideal combination of high speed, accuracy and connection flexibility. The analog inputs offer 18-bit resolution at sample rates up to 100 kilosamples per second. Each channel has an A/D converter, and all four channels are sampled simultaneously. The combination of the 18-bit resolution with the board's automatic offset zeroing and automatic gain calibration ensures extremely accurate measurements. Each channel also includes an anti-aliasing filter that automatically is configured to match the sample rate.
