NI PXIe-8840/QC | High-Performance Industrial Automation Controller

Description

PXIe-8840/QC: Product OverviewThe National Instruments PXIe-8840/QC is a flagship rugged PXI Express embedded controller designed to serve as the central “brain” of high-performance test, measurement, and automation systems. This quad-core controller combines powerful processing capabilities with industrial-grade durability, making it ideal for applications requiring reliable, real-time control in harsh environments

.As a critical component of NI’s PXIe modular ecosystem, the PXIe-8840/QC is engineered to unify and manage PXIe modules including digital I/O, analog acquisition, and timing modules. It leverages its Intel Core i7-8665UE quad-core processor to handle simultaneous tasks such as executing test sequences, processing high-volume data from connected modules, and synchronizing system-wide operations

.The controller’s rugged design features a -40°C to 70°C operating temperature range, 50g peak shock resistance, and 1.0g rms vibration tolerance, enabling operation in demanding industrial environments where commercial controllers would fail prematurely
