National Instruments PXIe-1081 PXI Chassis
The NI PXIe-1081 (part number: 790631-01) PXI Chassis supports PXI Express architecture with deterministic performance and controlled power delivery for modules. The unit operates from 100 to 240 VAC input sources with wide compatibility range. The chassis supports 100 to 120 VAC at 400 Hz operation for aerospace test systems. The operating voltage range extends from 90 to 264 VAC for global power standards. The input current ratings range from 10 A to 5 A operation under rated loads. The PXIe-1081 Chassis accepts nominal input frequencies of 50 Hz and 60 Hz standards compliance. It also supports 400 Hz nominal frequency for specialized power systems in aviation environments. The operating frequency range spans from 47 Hz to 440 Hz ensuring stable operation. The power supply achieves 85% typical efficiency during operation for reduced losses. Over current protection is provided by an internal fuse in line for safety assurance. Operating shock tolerance reaches 30 g peak with half sine pulses protection capability.
The specified pulse duration is 11 milliseconds for shock testing compliance verification procedures standards. The operational random vibration is rated from 5 to 500 Hz at 0.3 grms level. The NI PXIe-1081 uses design choices that maintain structural simplicity and its backplane slot comes with a 9 V current capacity. The PXI Chassis works with AC power supply design architecture. The chassis provides a total slot count of 18 for modules in PXI systems. It includes 17 hybrid slots supporting PXI and PXI Express modules simultaneously in systems. One dedicated slot ensures high bandwidth peripheral connectivity for controllers and switches.
The maximum system bandwidth is rated at 2 GB per second capacity. Slot cooling capacity is specified at 58 W per slot for thermal management efficiency. The unit uses a VCXO onboard clock for timing stability in synchronized measurements accuracy. It provides low phase noise and reliable frequency accuracy for PXI timing requirements. The PXIe-1081 PXI Chassis contains no external clocking. The external trigger access is also not available for synchronization purposes. The chassis does not include a redundant hardware power option by design specification. System timing slot functionality is not implemented in this configuration.
