Overview
The NI PXI-2531, PXIe-2531, PXI-2532, and PXIe-2532 are 512-crosspoint,
high-speed matrix switch modules. With the ability to create up to a 4x2176 or
8x1088 one-wire matrix in a single PXI chassis and even larger configurations
modules are built with sixteen 2x16 matrices, you can also create matrix sizes
outside the standard terminal block configurations. Other one-wire configurations
include a 16x32 matrix or four independent 4x32 matrices. In a two-wire
configuration, you can build a dual 4x32 or 16x16 matrix. Contact NI for more

speeds up to 2,000 cycles/s and the ability to synchronize with instruments,
these modules provide maximum throughput in a test system for signals up to
100 VDC/100 VAC or 0.5 A.
An NI 2531/2 counts relay closures on each of its 512 relays. Relay counts are
incremented each time a relay is actuated. You can programmatically retrieve
the counts, which are stored on board the module, and use them for predictive

maintenance to reduce unexpected system downtime.
The NI 2531/2 modules are general-purpose matrices used to route referenced

or differential signals. Through software, you can control the modules to connect
any row to any column. One of the key advantages of these matrices is you can
adapt them to your switching needs. You can configure them in many different
matrix configurations by using NI terminal blocks listed. For example, you can
create a 4x128 one-wire matrix by using the TB-2640 terminal block with an NI
2531/2 module. You can easily transform the same module into an 8x64
one-wire matrix by using a TB-2641 terminal block. Because the NI 2531/2
These modules maximize throughput in automated test applications by the
use of scanning. Scanning improves throughput by downloading a list of up to
32,000 connections to the switch and cycling through the list using an event
(trigger) without any interruption from the host processor. You can most
efficiently implement scanning by mating an NI 2531/2 with an instrument
such as the NI PXI-4070 6½-digit FlexDMM, which issues a trigger after
each measurement.

Signal Connections
You can choose from several solutions for your signal connections. Terminal
blocks provide connectivity to strain-relieved 0.050 in. pitch headers ideal for
ribbon cable or to 68-pin VHDCI connectors with cabled breakout accessories.
You also can use mass interconnect solutions from industry leaders such as
Virginia Panel and MAC Panel. Contact NI for details on these products or for
information on creating your own custom connectivity solutions.
