General Purpose Relay and Relay Driver Switch Modules: Switches Cable and Accessory Compatibility

Updated Sep 23, 2024

Overview

Use this guide to match your NI General Purpose Relay and Relay Driver 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 Relay Modules consist of multiple, independent, electromechanical armature relays and come in a variety of configurations, such as single-pole single-throw (SPST), single-pole double-throw (SPDT), and double-pole double-throw (DPDT) relays.

Note: This page does not include RF Relay Switches. To find compatibility information for NI RF Relay Switches see the RF Switch Module Compatibility Guide.

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

Known Limitations and Additional Information

This section is important to review because not every cable and accessory combination allows access to the full functionality of your NI General Purpose Relay device or module. This list contains notes about known limitations when using certain combinations of Switches cables and accessories. If your device or cable is not listed in this section, there are no known exceptions for it.


Review this table to identify potential limitations and known issues with your device or module.

Glossary of Terms Used

  • DIN (Deutsches Institut für Normung) Connector-  Industry standard connector that is used on 100-pin and 160-pin Switches cable and accessory connections.
  • 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.
  • LFH- Industry standard Low-Force Helix connector that is used on 160-pin and 200-pin Switches cable and accessory connections. 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.
