NI PXI-2501

Low-Voltage Multiplexer/Matrix FET Switch

Configure Page for: Print PDF Rich Text
  • 48x1 (1-wire), 24x1 (2-wire), 12x1 (4-wire) modes with TB-2605
  • 4x6 (2-wire) matrix mode with TB-2606
  • 1024-step scanlist for deterministic scanning
  • Easy instrument synchronization with hardware triggers
  • Fully software programmable


The National Instruments PXI-2501 performs as a multiplexer or matrix switch. The NI PXI-2501 is ideal for applications that require high-speed scanning of low-voltage signals (±10 V) because it uses FET switches with very low settling times (30 µs).

Since your device does not have direct signal connectivity, you need a terminal block to act as an interface between your sensors/signals and your device. A terminal block provides easy access to the inputs and outputs of your hardware.
The chassis provides rugged, modular housing for the controller and modules and contains the high-performance PXI backplane, which includes the system's data, timing, and triggering buses.
The controller runs your application and interfaces with your PXI modules.
You need software to interface with your hardware and to collect, analyze, present, and store your measurements. This board is compatible with a variety of programming languages, including LabVIEW, C/C++, Visual Basic, and .NET. LabVIEW provides the easiest integration with all of your NI hardware and is recommended to maximize your hardware investment.

System Assurance Programs

Reduce your setup time and total cost of ownership, and get a system you can use out of the box with National Instruments system assurance programs. System assurance programs include:

  • Installation and integration test of all individual hardware
  • Courtesy installation of system driver sets and application development environments
  • Extended warranty and calibration coverage for up to five years
  • Custom documentation plus a custom restore and startup utility

This service is only available for PXI, NI CompactRIO, and NI Compact FieldPoint systems.

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.
