The National Instruments PXI-1011 chassis (Part Number: 777965-01) is a versatile and high-performance solution designed for signal switching and conditioning applications. This chassis integrates an 8-slot SCXI subsystem with a 4-slot PXI subsystem, providing users with the capability to support a variety of modules, including digital I/O (DIO), multifunction I/O (MIO), and computer-based instrument modules. The chassis allows integration of multiple signal conditioning modules, which can provide digital and analog input conditioning and isolation. It features a maximum sampling rate of 333 kS/s and supports daisy chaining with additional SCXI chassis to enhance signal-conditioning channels. Its design incorporates advanced synchronization and timing capabilities, as well as integrated overcurrent and overvoltage protection for added reliability. The PXI-1011 also includes an interconnection for seamless integration of a DAQ or DMM module in the fourth PXI slot, enabling control of the SCXI subsystem without the need for extra cabling. The chassis operates within a broad input voltage range of 100 to 240 VAC with a power capacity of 140 watts. Its physical dimensions are 17.6 x 17.3 x 7.0 inches, and it weighs 20 pounds, providing flexibility for bench-top or rack-mounted configurations. The operating temperature range is 0 to 50 °C, while the storage temperature range is –20 to 70 °C. Although the PXI-1011 has been announced as obsolete by National Instruments, it remains available for purchase and repair through Apex Waves. The product is backed by a three-year warranty, and user and maintenance manuals are available for download. For pricing information, please contact a sales representative.
