National Instruments 784193-33 PXI-8840 Dual-Core PXI Embedded Controller
The National Instruments 784193-33 (PXI-8840) is a versatile 3U PXI embedded system controller designed for industrial automation, automated test bench setup, and data acquisition applications. Engineered around a dual-core Intel Core i5-4400E processor operating at 2.7 GHz with 3 MB of on-die cache, the module consolidates high-performance computing and essential peripheral I/O into a four-wide form factor that occupies one PXI system slot and three controller expansion slots. Memory performance is driven by 4 GB of single-channel 1600 MHz DDR3L SDRAM (PC3-12800) installed in a standard SO-DIMM socket, expandable up to 8 GB using NI-verified memory modules. Primary storage is anchored by a 2.5-inch 320 GB SATA hard drive, while an onboard watchdog timer provides configurable safety resets and trigger generations for continuous, unattended execution.
The front panel of the PXI-8840 offers a comprehensive array of connectivity options for test system integration. Visual outputs feature two DisplayPort 1.2 interfaces for dual-monitor configurations, supplemented by four Hi-Speed USB 2.0 ports and two SuperSpeed USB 3.0 ports for external drives and benchtop instruments. Dedicated networking and instrument control are handled via dual 10/100/1000Base-T Gigabit Ethernet ports with automatic crossover detection, an RS-232 serial port, a parallel port, and an integrated PCI-based IEEE 488.2 (GPIB) controller. For direct multi-module timing synchronization, the front-panel PXI trigger bus enables software-controlled routing of triggers across the chassis backplane, while an integrated ExpressCard/34 slot allows rapid expansion for specialized third-party I/O modules and additional storage. The controller comes pre-installed with a 64-bit Windows 7 Professional operating system for immediate software integration.
Mechanically constructed as a four-slot 3U PXI/CompactPCI module, the 784193-33 weighs 1.26 kg (2.77 lb) and draws operational power directly from backplane rails, consuming 1.12 A typical (1.84 A maximum) at +3.3 VDC and 8.92 A typical (14.97 A maximum) at +5 VDC. Built for continuous industrial service, the unit operates across an ambient temperature range of 5 °C to 50 °C (-40 °C to 65 °C storage) with an operational shock rating of 30 g peak (11 ms half-sine pulse) and a random vibration tolerance of 0.3 grms (5 Hz to 500 Hz) when configured with a solid-state drive.
