The National Instruments SCXI-1143 Lowpass Filter Input Module (Part Number: 776572-43) is designed to deliver high-performance filtering in industrial applications. This module features an 8th-order Butterworth filter response across eight differential channels, ensuring optimal antialiasing and maximum flatness within the specified passband. The SCXI-1143 supports a programmable cutoff frequency range between 10 Hz and 25 kHz, with specific frequencies selectable at fc = 100 kHz/n, where n can range from 4 to 10,000. Additionally, users can control the cutoff frequency with an external clock and have the ability to bypass the filters on each channel under software control as needed.

With a maximum sampling rate of 333 kS/s and ±30 V overvoltage protection while powered on, the SCXI-1143 is built for robustness and reliability in demanding environments. This module requires an SCXI-1304 or SCXI-1305 terminal block, an SCXI chassis or a PXI/SCXI combination chassis, an E/M Series DAQ instrument or SCXI-1600, and appropriate cabling. Users must also have NI-DAQ 7 driver software and a compatible software suite, including VI Logger, LabVIEW, Measurement Studio, or LabWindows/CVI, along with relevant manuals for proper operation. While National Instruments has announced that the SCXI-1143 is obsolete, it remains available for purchase and repair through Apex Waves. This module is backed by a warranty of 2 to 3 years. For detailed specifications and user support, manuals are available for download. For pricing, please contact a sales representative.
