PXI Matrix Switch Module
PXI Matrix Switch Modules are organized into rows and columns and provide maximum flexibility for switching systems by allowing you to connect any channel to any other channel. PXI Matrix Switch Modules use a variety of relay types, including electromechanical armature relays, reed relays, field-effect transistor (FET) relays, and solid-state relays, each with their own benefits, allowing you to choose a matrix that fits your requirements. To program the switches, you can use the IVI-compliant NI-SWITCH driver software, complete with help documentation, example programs, and a soft front panel application for interactive control of switches. For intelligent management of complex switch systems, NI Switch Executive provides additional software tools to help you design, build, and deploy your switching system.

PXI RF Relay Module
PXI RF Relay Modules offer single-pole double-throw (SPDT) and terminated switches. SPDT models include excellent insertion loss, voltage standing-wave ratio (VSWR), and isolation parameters to minimize signal degradation. You can use the onboard relay-count-tracking feature on these models to predict relay lifetime and reduce unexpected system downtime. SPDT models are also well-suited for passing high-order harmonics from PXI RF Signal Upconverter Modules or routing multiple sources to PXI RF Signal Downconverter Modules. Terminated switch models feature front-mounted SMA connectors and high-performance solid-state relays for fast switching time and unlimited mechanical lifetime. These models also include termination on every COM line and channel, which helps minimize reflections of the RF signal and protect your instruments.

PXI Relay Driver Module
The PXI Relay Driver Module controls up to 64 external relays with up to 50 VDC or 600 mA per channel drive capacity when using an external power supply. Modules can drive small DC motors or other inductive relay coils, and they include overcurrent, overvoltage, and flyback protection to ensure long operation. The PXI Relay Driver Module allows you to build custom switch configurations while using the standard IVIcompliant NISWITCH driver software.

PXI Signal Insertion Switch Module
PXI Signal Insertion Switch Modules, also known as fault insertion units (FIUs), provide a set of feedthrough channels, which make the switch transparent to the system when closed. You can open or short these channels to one of two fault buses, allowing you to simulate open or interrupted connections as well as shorts between pins, shorts to battery voltages, and shorts to ground on a per-channel basis. When controlled with the LabVIEW Real-Time Module, the PXI Signal Insertion Switch Module can validate the integrity of control systems including engine control units (ECUs) and full authority digital engine controls (FADECs). You can also use the FIU models for hardware-in-the-loop (HIL) applications and electronic reliability tests.

Matrix Module For SwitchBlock
The Matrix Module for SwitchBlock is for use with the PXI Carrier Module for SwitchBlock and can operate as an individual relay card, can combine with other Matrix Modules for SwitchBlock in the same PXI Carrier Module for SwitchBlock, and can combine with other Matrix Modules for SwitchBlock in other PXI Carrier Modules for SwitchBlock in the same PXI chassis. Each Matrix Module for SwitchBlock comes in an A-type version, which serves as the first matrix building block and offers row and column access through the front connector, and a B-type version, which serves as an expansion module and only provides column access through the front connector. Typically, SwitchBlock systems contain one A-type module and numerous B-type modules.
