Product Description
The National Instruments cDAQ-9178 CompactDAQ Chassis, with part number 781156-01, is a multifaceted data acquisition system that comprises eight slots for module integration and offers a generous input FIFO size of 127 samples per slot. The maximum sample rate of the chassis is determined by the specific C Series module being used, allowing for tailored performance based on measurement requirements.
Equipped with four 32-bit general-purpose counter/timers, the cDAQ-9178 is capable of a wide range of functions including edge counting, pulse width measurement, and position encoding, among others. It also facilitates the generation of pulses, pulse trains, and square waves, all with adjustable frequencies to suit diverse application needs. Users can access counter sources through hardware-timed digital I/O modules or via two dedicated PFI terminals on the chassis.
Integration with external systems is streamlined through two BNC connectors that enable sharing of clocks and triggers, while the option to use chassis trigger lines or a digital input module (such as the NI-9401 or NI-9411) provides additional versatility. The cDAQ-9178 operates using NI-DAQmx software, which supports an array of development environments like LabVIEW, LabWindows/CVI, C/C++, C#, and Visual Basic .NET, making it adaptable to various programming preferences.
Configuration is simplified with the Measurement & Automation Explorer (MAX) tool, and the presence of three AI timing engines allows the chassis to manage three analog input tasks concurrently, enhancing the throughput and efficiency of measurement systems.
