For new designs, NI recommends the NI PXI-2530B.
The NI PXI-2530 is a high-density, multiconfiguration multiplexer/matrix switch module. With four multiplexer and three matrix configurations, the PXI-2530 is an effective solution for complex or high-channel-count systems. Multiplexer configurations include 128x1 (1-wire), 64x1 (2-wire), 32x1 (4-wire), or eight banks of 16x1 (1-wire). Matrix configurations include 4x32 (1-wire), 8x16 (1-wire), or 4x16 (2-wire). You can implement these configurations by selecting the appropriate terminal block. With the speed of reed relays, the PXI-2530 is an ideal front-end component for high-speed measurement devices such as the NI PXI-4070 6½-digit FlexDMM. For parallel operations requiring lower-channel counts, consider the NI PXI-2576.
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
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.
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.
