National Instruments 782069-01 Ethernet CompactDAQ Chassis

Part number 782069-01 describes the cDAQ-9184, an Ethernet CompactDAQ Chassis from National Instruments. This chassis has temperature, voltage, and extension-based sensor estimation capabilities, meaning that the 782069-01 excels in analog input, analog output, and digital waveform functionality. 

The 782069-01 supports a range of channels, based on the requirements of the specific C Series module or modules that are being used. Up to 16 channels of the chassis are capable of hardware-timed tasks- supported by onboard regeneration. The max update rate of the 782069-01 is 1.6 MS/s for multi-channel aggregate use. The chassis features 50 ppm of precise timing accuracy, as well as a timing resolution of 12.5 ns. The output FIFO size varies, ranging from 8,191 samples (shared among onboard regeneration channels) to 127 samples per slot (with non-regeneration). Additionally, the 782069-01 offers various analog output waveform modes, enabling both non-periodic and periodic waveform regeneration modes from the onboard memory, as well as periodic waveform regeneration from the host buffer. 

The 782069-01 cDAQ-9184 chassis offers extensive data acquisition capabilities through a waveform acquisition FIFO that accommodates varying capacities of samples per slot for both parallel and serial modules. The digital input and output sample clock frequencies range from 0 MHz to 10 MHz, catering to multiple applications. 

The physical characteristics of the 782069-01 include screw-terminal wiring that support a gauge ranging from 20 AWG to 14 AWG of copper conductor wire. The torque required for the screw terminals accommodates one wire per screw terminal, and lies within the range of 0.20 N · m to 0.25 N · m (equivalent to 1.8 lb · in. to 2.2 lb · in.). The torque specifications for the screw flanges align within the same defined range as the screw terminals, ensuring secure and stable connections. The temperature rating for the 782069-01 is 185°F (85°C).
