Overview

The NI PXI-2529, PXIe-2529, and SCXI-1129 are high-density matrix relay

modules built for applications with high-channel counts. The modules are

two-wire matrices that are configurable with front mounting terminal blocks to

achieve many different matrix configurations. Table 1 provides a complete list of

possible configurations. Expanding the matrix channel count is as easy as adding

more modules. With the SCXI-1129, you can pass analog signals between two

or more switch modules via a high-voltage backplane (HVAB), matrix expansion

cables, or matrix expansion plugs. Using these connections, you can instantly

expand your matrix without external wiring. The NI 2529 modules are designed

to work well with both low- and high- voltage levels. They use relays with low

thermal offset to ensure accurate low-voltage measurements. These relays can

switch up to 150 V

Matrix Operation

The NI 2529 modules are general-purpose,

two-wire matrices used to route differential

signals. Through software, you can control

the matrices to connect any row to any

column. One of the key advantages of

these modules is their adaptability to

your switching needs. You can configure

the SCXI-1129 in six different matrix

configurations and an NI 2529 in two

configurations by simply changing the terminal block. For example, you can

create an 8x32 two-wire matrix by using the NI SCXI-1335 terminal block with an

SCXI-1129 module. You can easily transform the same SCXI-1129 module into a

16x16 two-wire matrix by simply replacing the SCXI-1335 with an NI SCXI-1336

terminal block.

state of each matrix remains unchanged in the event of accidental power loss.

This feature prevents instruments and units under test from switching during

potentially damaging conditions. All relays open when power returns.

Automatic Scanning

NI 2529 modules can maximize throughput in automated test applications with

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 2529 or SCXI-1129 with an

instrument such as the NI PXI-4070 6½-digit FlexDMM, which issues a trigger

after each measurement.

Safety Disconnect

The SCXI-1129 incorporates a safety interlock that disconnects the SCXI

high-voltage analog bus from the matrix if the front terminal block is removed.

This arrangement prevents potentially hazardous voltages from appearing on

exposed front panel connector pins.

The NI 2529 modules use latching relays in the matrices to ensure that the
