The National Instruments SCXI-1129 is a high-density matrix built to serve high-channel-count switching applications. The module is a 2-wire matrix, configurable with front mounting terminal blocks to achieve many different matrix configurations, including 4x64, 8x32, 16x16, dual 4x32, dual 8x16, quad 4x16. For greater densities, matrix expansion is easily achievable with additional modules. Analog signals are passed between modules via a high-voltage backplane, a matrix expansion cable, and through analog plugs connecting terminal blocks, which virtually eliminate hours of complicated wiring. The NI SCXI-1129 is designed to work well with both low and high-voltage levels. For low-voltage measurements, the SCXI-1129 uses relays with low thermal offset to ensure accurate measurements. These same relays can handle up to 150 Vrms and 150 VDC.

Extended Warranties

National Instruments designs and manufactures all products to minimize failures, however unexpected failures can still occur. Extended warranties provide a fixed economical price at the time of system purchase, covering any repair costs for up to three years. In addition, they offer the following benefits:

  • Significant cost savings compared to individual repair incidents
  • Fault location, diagnostics, and repair by NI any time the system product fails
  • All parts and labor costs covered as well as any adjustments needed to restore the hardware to manufacturing specifications

For more information about your warranty options:

Calibration

NI recognizes the need to maintain properly calibrated devices for high-accuracy measurements. NI provides manual calibration procedures, services to recalibrate your products, and automated calibration software to calibrate many NI measurement products.

Training

NI training is the fastest, most certain route to productivity with NI tools and successful application development.

Repair Services

Return your registered product under warranty at no additional labor and parts cost. NI offers fault location, diagnostics, and repair any time the system fails as well as any adjustments needed to restore the hardware to manufacturing specifications.
