The National Instruments part number 778693-01 refers to the PXI-1052, a robust 12-slot PXI Chassis designed for high-performance automation and control applications. This chassis integrates a 4-slot PXI subsystem with an 8-slot SCXI subsystem, providing a comprehensive solution for precision signal conditioning and switching tasks. Adhering to the PXI Hardware Specification, the PXI-1052 supports advanced timing and synchronization features essential for seamless data acquisition operations. The 8 SCXI slots are dedicated to both analog and digital signal conditioning, offering capabilities such as isolation and enhanced measurement accuracy within a low-noise environment. The integrated digital and analog bus facilitates direct communication between PXI and SCXI subsystems, enabling efficient control of the SCXI modules without the need for additional cabling when utilizing a DAQ or DMM module in the fourth PXI slot.

This chassis operates within an input voltage range of 100 to 240 Volts AC, with a required operating voltage of 90 to 264 Volts AC, and supports an operating frequency of 47 to 63 Hz. It has an input current rating of 3 to 6 Amperes and is equipped with a 10 Ampere circuit breaker for over-current protection, ensuring safety and reliability. The chassis is designed for operation in ambient temperatures between 0 °C and 55 °C and is capable of withstanding relative humidity levels from 10% to 90%, non-condensing. Its physical dimensions are 177 mm × 438.2 mm × 452.9 mm (6.97 in. × 17.25 in. × 17.83 in.), with a weight of approximately 10 kg (22.0 lbs). Constructed from sheet aluminum, extruded aluminum, cold-rolled steel, PC/ABS, Santoprene, and nylon, the chassis features a corrosion-resistant enclosure with a conductive clear Iridite finish on aluminum and an epoxy/polyester powder coat, ensuring durability in industrial settings.
