◾ ◾

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

with multichassis solutions, an NI 2531/2 is ideal for high-channel-count

automated test configurations. Featuring compact reed relays with switching

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.

Matrix Operation

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

Module Connector

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

information on creating custom configurations.

Relay Count Tracking

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.

Automatic Scanning

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.
