National Instruments 784058-01 PXI Chassis

The part number 784058-01 from National Instruments is the identifying part number for the PXIe-1084 PXI Chassis. The 784058-01 PXI Chassis combines a high-performance 9 PXI express slots supporting both PXIe and PXI modules. It features a high power backplane system with a 10MHz system reference clock and synchronization capability, ensuring high accuracy. The Backplane System is equipped with backplane connectors that conforms to IEC 917 and IEC 1076-4-101, UL 94 V-0 rated. This chassis has an input voltage rating of 100 to 240 VAC with an input frequency range of 50 Hz to 400 Hz. This chassis has an typical efficiency of 80%.

The 784058-01 PXI Chassis features backplane current slot capacity of 9 Amps at +5 Volts of PXI express system controller slot and 6 Amps at +5 Volts of hybrid peripheral slot with PXI-1 peripheral. The chassis supports universal AC input with auto-voltage and auto-frequency ranging. In case of overcurrent, all outputs are protected from short circuit and overload with automatic recovery.

For internal cooling, the 784058-01 PXI Chassis features module cooling with forced air circulation (positive pressurization) through three 210 CFM fans with High/Auto speed selector with module slot airflow direction from bottom of module to top of module. It has a slot cooling capacity of 58 Watts as well as secondary cooling forced air circulation (positive pressurization) through one 70 CFM fan.

This PXI chassis is designed to operate at an ambient temperature of 0 to 50 degrees Celsius up to 38 W per peripheral slot and 0 to 40 degrees Celsius up to 58 W per peripheral slot with a relative humidity range of 10% to 90%, noncondensing. It has a storage temperature of –40 to 71 degrees Celsius and Relative humidity range of 5% to 95%, noncondensing. The 784058-01 is engineered to endure harsh working conditions with operational shock of 30 g peak, half-sine, 11 ms pulse and operational random vibration of 5 to 500 Hz, 0.3 grms with non-operating vibration of 5 to 500 Hz, 2.4 grms. The PXI chassis also involves acoustic emission monitoring with auto fan that detects sound levels up to 34.4 dBA and high fan of up to 55.0 dBA.
