National Instruments 777965-01 Chassis

The part number 777965-01 from National Instruments is the identifying part number for the PXI-1011 Chassis. The 777965-01 Chassis features a 4-slot PXI subsystem and an 8-slot SCXI subsystem which are compliant with the PXI Specification Revision 2.0. This subsystem offers clock and time synchronization features for higher precision measurements. The SCXI subsystem is designed for signal conditioning application making it crucial for accurate data acquisition from various sensors and transducers.

The 777965-01 Chassis is unique because it offers its own built in cooling system which employs forced air circulation with positive pressurization by using 2 fans to help cool all the modules installed in this chassis. The cooling system in the 777965-01 Chassis is designed to maintain the operating temperatures of the modules installed in this chassis even when the modules are running in heavy duty mode. This chassis has an input voltage range of 100 Volts AC to 240 Volts AC operating at 3 phase with a frequency rating of 47 to 440 Hertz making it compatible with power systems in different regions around the world. To prevent electrical accidents, the 777965-01 Chassis features both overvoltage and overcurrent protection features.

The 777965-01 chassis is designed to withstand operational shocks and vibration which meet the MIL-T-28800E Class 3 specifications. This module is designed to operate in an environment with temperatures ranging from 0 degrees Celsius to 50 degrees Celsius and can be stored in environments as harsh as -20 degrees Celsius to 70 degrees Celsius. The chassis is also designed for indoor use with a pollution degree rating of 2, ensuring it can handle a variety of operational environments.

This chassis does not come with an Ingress protection or the IP protection rating and hence is required to be operated in environments protected from dust and moisture as it can affect the internal circuitry and the overall performance of the module. For installation and maintenance refer to the guide provided by NI Instruments. The chassis should be mounted at a maximum of 2000 meters above the sea level for optimum operation and performance of the modules.
