Programmable Resistor Switch Modules: Switches Cable and Accessory Compatibility

Updated Jan 4, 2023

Overview

Use this guide to match your NI Programmable Resistor Switch models PXI or PXI Express (PXIe) device with a compatible cable and accessory to meet the needs of your application, whether you are creating a new configuration, replacing or expanding your current configuration, or verifying that existing parts can be used in a different configuration.

PXI Programmable Resistor Modules replicate the behavior of resistance‐based devices by controlling a series of relays that varies resistance across each channel. The ability quickly and accurately vary resistance, with resolution down to 0.25Ω, makes these devices well‐suited for simulating environmental conditions in hardware‐in‐the‐loop (HIL) validation.

This page is part of the NI Switches Cable and Accessory Compatibility Guide.

How to Use this Guide

It is important to work through this guide sequentially to identify and then pair up your device with compatible cables and accessories. To do this, complete the following steps:

Find your module or device in the Device List.
Use the Cable and Accessory Compatibility Tables to identify your device.
Note: Using the page search functionality in your browser to locate your model may speed up this process, typically CTRL+F on Windows or ⌘+F on MacOS.

Device List

Begin by using the following tables to locate your device or module. Once found, note your connector type, pin count, and any other notes for reference, and then move to the Cable and Accessory Compatibility Tables.

Important Note: "Group" used in this context is solely to categorize devices together that use the same cables and accessories. It does not necessarily indicate similar functionality, specifications, or other commonalities between the devices.

Group 1: Programmable Resistor Device And Modules

Identify your Programmable Resistor device or module, then click to jump to the compatibility table.
Model	Connector Type
PXI-2720	D-Sub 37-pin
PXI-2722	D-Sub 37-pin
PXIe-2725	D-Sub 37-pin
PXIe-2727	D-Sub 37-pin

Cable and Accessory Compatibility Tables

Find the compatibility table that matches the pin count and connector type of your device. If you have questions on terminology, refer to the Glossary below.

Glossary of Terms Used

D-Sub (DSUB) - Industry standard D-shaped connector that is used on 8-pin, 37-pin, 62-pin, 78-pin Switches cable and accessory connections. Click here for an example.
Front Mounted Terminal Block- An accessory solution that connects directly to the front of a module. These accessories can be shield or unshielded, they also can allow for the user to directly access the signal on the front of the module or may require additional cabling or accessories to access the device signals. Click here for an example.
Remote Terminal Block- An accessory solution that requires a cable to connect to the module. This accessory can be connected, using the cable, directly to the module, or it can be connected, using a cable, to additional accessories. Click here for an example.
