NEWS RELEASE – Sept. 13, 2005 – National Instruments today announced the release of the NI PXI-4224, a 60 V DC, Cat. I, channel-to-channel isolated data acquisition module that provides eight channels of 16-bit analog input measurements. This new module is especially useful for industrial applications requiring highly accurate, small-signal measurements with a high common-mode voltage and protects the measurement system from possible voltage spikes or power surges, ensuring the safety of users and protection of expensive equipment. With the new PXI-4224 data acquisition module, scientists and engineers now can take measurements in an industrial setting where voltage spikes and transient signal inputs often occur.
In addition, the included channel-to-channel isolation eliminates ground loops and provides better noise immunity. Designed to work with LabVIEW 7 Express and NI-DAQmx measurement services software, the new module features integrated signal conditioning and provides programmable gain settings per channel to ensure maximum measurement accuracy. The 333 kS/s sampling rate and 16-bit resolution offer the flexibility to measure a broad range of signals with highly accurate voltage measurements.
