Description
The part number 776572-29 is associated with PXI Switches, specifically the model SCXI-1129. This model is designed with a highly versatile configuration, capable of functioning as a 4 x 64, 2-wire switch matrix at its maximum capacity. It also offers flexibility by being able to operate as four 4 x 16, two 4 x 32, or two 8 x 16, 2-wire matrixes, catering to a wide range of connectivity needs.
It boasts a maximum scan rate of 100 crosspoints per second, ensuring efficient and rapid signal routing. The SCXI-1129 utilizes various relay types, including electromechanical, latching, and nonlatching, to accommodate different application requirements. Notably, the thermal offset is exceptionally low, at less than 9 µV, minimizing signal distortion and ensuring high measurement accuracy.
Analog bus support is available with the SCXI-1357/1358 high-voltage analog bus backplane adapter, enhancing the module’s functionality and integration capabilities. Compatibility is further extended to various terminal blocks, including SCXI-1336, SCXI-1333, SCXI-1335, SCXI-1337, SCXI-1334, and SCXI-1339, offering a wide array of connection options to meet diverse system requirements.
Software support includes NI-SWITCH and NI-DMM; the module is also compatible with popular programming environments such as LabVIEW, Measurements Studio, and Visual Basic, enabling easy integration into existing systems and simplifying the development process.
The physical dimensions of the SCXI-1129 are 7.8 x 1.2 x 6.8 inches, with a weight of 1 lb., making it compact and lightweight for easy installation in various setups. Although its obsolete status has been announced by National Instruments, it remains available for purchase and repairs through Apex Waves, ensuring continued support for existing users.
