Product Overview
The NI PXI-8186 is a high-performance embedded controller designed for the PXI and CompactPCI systems, serving as a critical computational core in industrial automation and test measurement applications. This module integrates a Mobile Intel Pentium 4 processor operating at 2.2 GHz or 2.5 GHz, supported by up to 1 GB of DDR memory, enabling robust data processing, control logic execution, and communication management within modular instrumentation platforms . As part of NI’s PXI ecosystem, the PXI-8186 aligns with the industry-standard architecture defined by the PXI Systems Alliance (PXISA), ensuring interoperability with a wide range of peripheral modules for applications requiring precise timing, synchronization, and high-speed data acquisition . Its compact, single-unit design consolidates standard PC peripherals—including Ethernet, USB 2.0, GPIB (IEEE 488.2), and serial ports—into a streamlined form factor, eliminating the need for external cabling and reducing system integration complexity .
By leveraging the PXI platform’s built-in triggering and synchronization capabilities, the NI PXI-8186 delivers reliable performance in harsh environments, with extended temperature tolerance and ruggedized construction suitable for aerospace, military, and automotive testing scenarios. The controller optimizes slot usage in PXI chassis by housing peripherals onboard, allowing all active slots to be dedicated to measurement modules such as digitizers, switches, or analog I/O cards . This approach enhances system scalability while maintaining low latency and high throughput, making the NI PXI-8186 a versatile solution for real-time control, data logging, and advanced analysis tasks in research and production settings .
