The National Instruments PXI-2527 is a high-voltage multiplexer switch module designed for medium- to high-density automated test systems. With a switching capacity of up to 300 VDC/300 VAC andup to 2 A, the NI PXI-2527 is the perfect front end for the NI 4070 and NI 4072 digital multimeters, offering simple channel expansion for voltage, current, resistance, capacitance, or inductance measurements. Multiple-channel configurations are available including 64x1 1-wire, 32x1 2-wire, and 16x1 4-wire. Each channel,using robust electromechanical relays, is capable of scanning up to 120 channels/s. A cold-junction compensation (CJC) sensor is also included in the front-mounting terminal block to assist in thermocouple scanning applications.

NI PXI-2527 Packages
To use the NI PXI-2527 , you need all items in the diagram below. Select Option 1 if you already own a PXI System, or Option 2 if you do not already own a chassis, controller, or software.
Roll over the icons below to learn why you need each item in the system
Choose from hundreds of specialized instruments to create a PXI System that suits your measurement needs and can scale for future applications. Then, we'll help you choose the right hardware and software to complete your configuration.
Add More Measurements and I/O Modules Use the PXI Advisor to choose from a variety of modules including analog I/O, digital I/O, switching and more. Then, complete and price the PXI System.
Preview a Complete System View and price a complete PXI configuration including the NI PXI-2527, chassis, and controller. Starting from the default configuration, you can add modules, accessories, and software and customize your system.
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.
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.
