National Instruments 785158-33 PXIe-8821 Dual-Core PXI Express Embedded Controller
The National Instruments 785158-33 (PXIe-8821) is a cost-effective 3U PXI Express embedded system controller engineered for automated test, measurement, and control applications. Built around a dual-core Intel Core i3-4110E processor running at a 2.6 GHz clock frequency with 3 MB of on-die cache, the module delivers dependable processing power and system-level management. Memory is pre-configured with 2 GB of single-channel 1600 MHz DDR3L SDRAM (expandable up to 8 GB), while a 2.5-inch 320 GB SATA hard drive serves as the non-removable primary storage medium. Fully compliant with PXI Express Specification 1.0, the controller delivers up to 2 GB/s maximum system bandwidth across the backplane, supporting both 4-link and 2-link PXI Express slot configurations.
Front-panel peripheral interface connectivity features two Hi-Speed USB 2.0 ports and two SuperSpeed USB 3.0 ports for connecting external drives, peripherals, and instruments, alongside integrated support for PXI trigger bus input and output operations. The controller comes pre-installed with a 64-bit Windows 7 Professional for Embedded Systems operating system, providing broad software compatibility with NI LabVIEW, TestStand, and standard Windows-based test environments.
Constructed as a four-wide 3U PXI Express module occupying one system slot plus three controller expansion slots, the 785158-33 weighs approximately 0.98 kg (2.16 lb). System power is drawn directly from backplane power rails, consuming 2.86 A typical (4.82 A maximum) at +12 V, 0.93 A typical (2.15 A maximum) at +5 V, 1.09 A typical at +3.3 V, and 0.19 A typical on the +5 V auxiliary line. Rated for indoor deployments up to 2,000 meters altitude, the controller operates reliably across an ambient temperature range of 5 °C to 50 °C (-40 °C to 65 °C storage) under relative humidity levels of 10% to 90% non-condensing (5% to 95% storage), with operational shock resistance rated to 30 g peak (11 ms half-sine) and random vibration tolerance of 0.3 grms from 5 Hz to 500 Hz (2.4 grms non-operational).
