The National Instruments cDAQ-9184, part number 782069-01, is an advanced Ethernet CompactDAQ chassis designed to enhance data acquisition capabilities across a variety of industrial applications. This chassis facilitates sensor estimation for temperature and voltage through its robust support for analog input, analog output, and digital waveform functionality. Depending on the C Series modules utilized, the cDAQ-9184 can accommodate up to 16 channels for hardware-timed tasks, with an impressive aggregate maximum update rate of 1.6 MS/s. The chassis is equipped with precise timing accuracy of 50 parts per million and a timing resolution of 12.5 ns.

The cDAQ-9184 features a waveform acquisition FIFO that supports varying sample capacities, thereby optimizing performance for both parallel and serial modules. The output FIFO sizes range from 127 samples per slot for non-regeneration scenarios to 8,191 samples shared among regeneration channels, allowing flexibility in waveform regeneration modes. Digital input and output capabilities offer sample clock frequencies from 0 MHz to 10 MHz, accommodating diverse operational requirements.

Constructed with durable screw-terminal wiring capable of accommodating copper conductor wire gauges from 20 AWG to 14 AWG, the cDAQ-9184 ensures secure connections with a torque specification of 0.20 to 0.25 N·m (1.8 to 2.2 lb·in) for optimal stability. It maintains a temperature rating of up to 185°F (85°C), making it suitable for demanding environments. The cDAQ-9184 is backed by a three-year warranty, underscoring National Instruments' commitment to quality and reliability.
