National Instruments 785065-01 CompactDAQ Ethernet Chassis
Often called the cDAQ-9189, the National Instruments 785065-01 is a sophisticated 8-slot CompactDAQ Ethernet chassis intended for distributed sensor measurement systems. Users can mix and match different modules to create a flexible combination of analog I/O, digital I/O, and counter/timer measures due to this chassis, which controls timing, synchronization, and data transfer between C Series I/O modules and an external host. The 785065-01 is perfect for widely dispersed measurements over long distances because it uses Time-Sensitive Networking (TSN) to provide accurate, synchronized time over a network. The inbuilt network switch also makes setup simpler by facilitating simple daisy-chaining.
The 785065-01 can function well and use a maximum of 16W of power within a voltage input range of 9V to 30V. Its small size of 10.74 inches by 3.47 inches by 2.45 inches, along with its IP40 ingress protection and working temperature range of -40°C to 70°C, guarantee dependable operation in a variety of settings. For field and industrial applications that need reliable performance in challenging circumstances, its sturdy design is appropriate.
Because it is compatible with C Series modules, the 785065-01 offers a wide range of measurement possibilities. Each slot provides an input FIFO capacity of 127 samples for analog input, with the installed modules dictating the maximum sample rate. With its many internal base clocks—80 MHz, 20 MHz, 13.1072 MHz, 12.8 MHz, 10 MHz, and 100 kHz—it guarantees accurate timing at 50 ppm of sample rate.
For analog outputs, the 785065-01 supports hardware-timed tasks with onboard regeneration for up to 16 channels and non-regeneration, where the number of supported channels depends on the C Series module(s). Non-hardware-timed tasks are also supported with the number of channels again determined by the modules in use.
The digital waveform characteristics include a waveform acquisition (DI) FIFO of 511 samples per slot for parallel modules and 63 samples per slot for serial modules. The 785065-01 includes four 32-bit general-purpose counters/timers, which are ideal for applications involving quadrature encoders, PWM, pulse train generation, edge counting, pulse width measurement, and more. These counters/timers support edge counting, pulse, semi-period, period, two-edge separation, pulse width, and position measurements with resolutions up to X4 quadrature encoding with Channel Z reloading. Output applications include pulse, pulse train with dynamic updates, frequency division, and equivalent time sampling, with an output frequency range of 0 MHz to 20 MHz.
