National Instruments 780321-01 Multifunction PXIe Chassis

The 780321-01 is an identifying part number for the PXIe-1082, a high-performance 8-slot PXI Express (PXIe) chassis designed by National Instruments for versatile applications in test and measurement systems. With its sturdy structural design and high-performance power supply, this chassis provides the best possible reliability and usability. Because of its modular design, which guarantees simple maintenance, the mean time to repair (MTTR) is short.

The chassis is designed to accommodate a wide range of PXI Express modules and can handle data transfer rates of up to 8 GB/s, making it suitable for demanding test and measurement applications. It provides flexible module compatibility with 4 hybrid slots and 2 dedicated PXI Express slots. A PXI Express System Timing Slot is also available on the chassis for accurate synchronization in time-sensitive applications.

The 780321-01 has an operational voltage range of 90 to 264 VAC and an AC input range of 100 to 240 VAC, which guarantees compatibility with various power sources. A 10 A circuit breaker is used to provide over-current protection, which improves safety while in use.

In order to provide optimal airflow from the bottom to the top of the modules, the chassis uses two 110 cfm fans to drive air circulation for effective cooling. Exhaust is routed along the top, sides, and bottom of the chassis, with the module cooling intake located at the bottom rear. On the right and left sides of the chassis, respectively, are the intake and exhaust for the forced air circulation system used by the power supply cooling system.

In terms of operating environment, the chassis can function within an ambient temperature range of 0 °C to 55 °C and a relative humidity range of 10% to 90%, non-condensing. For storage, it can withstand temperatures ranging from -40 °C to 71 °C and a relative humidity range of 5% to 95%, non-condensing.

The 780321-01 chassis meets stringent shock and vibration standards, with operational shock resistance up to 30 g peak and half-sine pulse of 11 ms. It can withstand random vibrations ranging from 5 to 500 Hz.
