National Instruments 784781-01 10-Slot PXI Express Chassis
The National Instruments 784781-01 is a top-quality 10-slot PXI Express Chassis. It is also identified as the PXIe-1092 module and is designed for high-performance test and measurement applications. The chassis features a high-bandwidth backplane and offers up to 82 W of power and cooling per slot. The all-hybrid backplane provides flexibility by accommodating PXI Express modules in every slot and PXI hybrid-compatible modules in up to seven slots.
The AC input of the 784781-01 chassis supports a wide operating voltage range from 90 to 264 VAC along with a nominal input frequency of 50 Hz/60 Hz/400 Hz. It ensures efficient power usage with an 85% typical efficiency. Over-current protection is provided by an internal fuse, and the main power disconnect is facilitated through the AC power cable. The front-panel power switch controls the internal chassis power supply, while an optional rear-panel 15-pin connector and inhibit mode switch offer additional control options.
The NI 784781-01 includes a built-in oven-controlled crystal oscillator (OCXO) for precise timing and synchronization. This enhances clock accuracy and allows external clock and trigger routing. The chassis features a peripheral expansion slot in Slot 10, which supplies power for multiple-slot wide modules. In addition, it delivers a maximum total power of 988 W across various voltage rails, as DC output. This includes +5VAUX at 3 A, +12 V at 74 A, +5 V at 26.5 A, +3.3 V at 36 A, and -12 V at 1.75 A. The power supply offers over-current and over-voltage protection and has a mean time to repair (MTTR) of under one minute.
The cooling system of the 784781-01 uses forced air circulation with 2 x 210 CFM fans for module cooling and a secondary 70 CFM fan. This setup maintains efficient cooling from the bottom to the top of the modules. Proper cooling clearances are required to ensure optimal airflow and system performance.Environmental specifications of the NI 784781-01 module include a maximum operating altitude of 4,600 m and a wide operating temperature range (0 to +55 degree Celsius or 0 to 40 degree Celsius) that depends on the cooling requirements of peripheral modules. The chassis also meets several safety and electromagnetic compatibility standards.
