NI Unveils Data Acquisition Devices with Integrated Signal Conditioning

7/23/2003 - National Instruments announced the PXI-4204 and PXI-4220, the first two products in the new SC Series of data acquisition (DAQ) devices with integrated signal conditioning. The new SC Series seamlessly integrates with LabVIEW 7 Express, making it faster and easier to acquire and analyze high-voltage and high-speed strain with 16-bit measurement accuracy.

Each device in the new SC Series integrates measurement-specific signal conditioning onto a 16-bit PXI data acquisition module and provides simultaneous sampling at rates up to 200 kS/s. Engineers and scientists can reduce development time and save space by connecting signals or sensors directly to these data acquisition modules, eliminating the need for external, front-end signal conditioning.

The PXI-4220 module is designed for structural test and aerospace applications, including high-speed strain, load and pressure measurements. The 100 V input range of the PXI-4204 module makes it ideal for high-voltage applications, such as 14 and 42 V automotive measurements.

In addition to providing new measurement capabilities in an integrated platform, these two PXI DAQ modules also deliver a lower price point than traditional systems for low-channel-count applications. For eight-channel solutions, SC Series devices provide a cost savings of up to 46 percent over NI and other leading market solutions, such as an E Series DAQ device connected to NI SCXI signal conditioning. NI SCXI signal conditioning is ideal for applications requiring additional sensor inputs or higher channel counts. The PXI-4204 and PXI-4220 modules also utilize the PXI bus, so you can synchronize timing and triggering signals between multiple devices.
