National Instruments PXI-2529 128-Crosspoint Matrix Switch

  • Multiple-Module Synchronization
  • 1A Switching / 2A Carry
  • 8 Matrix Configurations


The NI PXI-2529 is a high-density matrix relay module built for applications with high-channel counts. The modules are two-wire matrices that are configurable with front mounting terminal blocks to achieve many different matrix configurations. Table 1 provides a complete list of possible configurations. Expanding the matrix channel count is as easy as adding more modules. With the SCXI-1129, you can pass analog signals between two or more switch modules via a high-voltage backplane (HVAB), matrix expansion cables, or matrix expansion plugs. Using these connections, you can instantly expand your matrix without external wiring. The NI 2529 modules are designed to work well with both low- and high-voltage levels. They use relays with low thermal offset to ensure accurate low-voltage measurements. These relays can switch up to 150 Vrms or 150 VDC.
