Key product information and technical features.
NI PXIE-8374 is a PXI Bus Extension Module that NI describes as a PXIe, x4, MXI-Express daisy-chain copper interface for creating multichassis PXI systems. It is a PXI Express peripheral-slot module rather than a host PC card, intended to extend a PXI Express system by linking additional expansion chassis over MXI-Express x4 copper cabling. NI identifies the commercial catalog model as PXIe-8374 with part number 781820-04, while the published specifications apply specifically to PXIe-8374 assembly 193970x-02L.
Within a system, the PXIe-8374 is used in the chassis expansion role. NI’s getting started material places PXIe-8374 in the “Connecting Additional Expansion Chassis to a System” position, and NI’s expansion guide lists its installation location as any PXI Express peripheral slot in the master or slave PXI Express chassis. The module uses a PXI Express bus connector, supports MXI-Express x4 communication, and NI lists a theoretical bandwidth of 1 GB/s over copper cabling.
Mechanical and environmental data in NI’s specifications support integration planning. The module requires one peripheral slot in a PXI Express or CompactPCI Express system. NI specifies maximum cable length of 7 m, dimensions of 10.0 × 16.0 cm, and typical weight of 0.16 kg. Power consumption is specified from the +3.3 V, +12 V, and +5 VAUX rails, and the module is rated for 0 to 55 °C operation with noncondensing humidity from 10 to 90%.

Product-specific answers based on available technical information.
NI identifies the PXIe-8374 as a PXI Bus Extension Module with a PXIe, x4, MXI-Express daisy-chain copper interface.
No. NI documentation places the PXIe-8374 in the role of connecting additional expansion chassis to a system, and the expansion guide lists it for installation in a PXI Express peripheral slot in the master or slave chassis.
NI specifies a maximum cable length of 7 m for the PXIe-8374.
NI states that the specifications apply to PXIe-8374 (193970x-02L) only, so assembly number confirmation may be necessary when matching a specific unit to the published spec sheet.
