PXIe-1086DC

The PXIe-1086DC is a PXI Express Chassis from National Instruments, designed for high-availability automated test, measurement, control, RF validation, data acquisition, and modular instrumentation systems. As an 18-slot PXI Express chassis, the NI PXIe-1086DC provides a large modular platform for building high-channel-count PXI test systems. It includes 16 hybrid slots, 1 PXI Express slot, a DC power supply, and up to 12 GB/s system bandwidth. NI lists the PXIe-1086DC with part number 787137-01.

The NI PXIe-1086DC is designed for systems that require high uptime and reliable long-term operation. Unlike standard PXI chassis with a basic power and cooling configuration, the PXIe-1086DC incorporates hot-swappable redundant DC power supplies and hot-swappable front-accessible redundant cooling fans. These high-availability features help improve system serviceability by reducing downtime when maintenance or replacement is required.

One of the main advantages of the PXIe-1086DC PXI Express Chassis is its hybrid slot design. The chassis provides 16 hybrid slots, which gives engineers flexibility when combining PXI, PXI Express, CompactPCI, and CompactPCI Express modules in one system. This makes the PXIe-1086DC suitable for users who need to integrate legacy PXI modules with newer high-bandwidth PXI Express instruments in a single chassis. NI’s PXI Express chassis brochure also highlights hybrid slot compatibility as an important feature for instrumentation flexibility.

The National Instruments PXIe-1086DC provides up to 12 GB/s total system bandwidth, allowing high-speed data communication between the controller and installed PXI Express modules. This bandwidth is useful for systems using digitizers, oscilloscopes, RF instruments, signal generators, source measure units, switch modules, and high-speed DAQ modules. For applications that generate large datasets or require fast instrument communication, the PXIe-1086DC provides a strong PXI Express backplane for scalable test system integration.

The PXIe-1086DC also includes system monitoring features that help users track chassis health during operation. It monitors power supply health and voltages, air intake temperature, and fan health and speed, with failure feedback provided through chassis status LEDs. These monitoring functions are valuable for test, measurement, and control applications where system uptime, thermal management, and power reliability are important.

For power input, the PXIe-1086DC supports a DC operating voltage range of 210 VDC to 300 VDC. Its specifications also list an AC operating range of 90 VAC to 264 VAC, which means it can support both DC and AC input configurations depending on the system setup and power cabling. This power flexibility makes the chassis useful for industrial, aerospace, defense, and field-deployed systems where DC power infrastructure may be required.

The PXIe-1086DC PXI Express Chassis is suitable for demanding applications such as automated production test, high-channel-count data acquisition, RF and wireless validation, semiconductor test, aerospace and defense systems, hardware-in-the-loop testing, and industrial measurement platforms. Its 18-slot capacity allows engineers to install multiple measurement, switching, timing, RF, and signal-processing modules in one chassis, making it a practical choice for large and complex PXI systems.

Overall, the NI PXIe-1086DC PXI Express Chassis is a high-availability 18-slot chassis for advanced PXI and PXI Express test platforms. With 16 hybrid slots, 1 PXI Express slot, DC power supply support, hot-swappable redundant power supplies, redundant cooling fans, system health monitoring, and up to 12 GB/s system bandwidth, the PXIe-1086DC is well suited for mission-critical automated test, modular instrumentation, and high-reliability measurement applications.
