Description
The NI-9474 is a high-end digital output module that is part of the C Series Digital I/O category. It comes with part numbers 779003-01 and 783908-01, offering flexibility in connectivity with options for Screw Terminal and Spring Terminal respectively. This module is designed to work seamlessly with CompactDAQ and CompactRIO systems, ensuring broad compatibility.
Featuring 8 digital output channels, the NI-9474 is capable of handling logic levels of 12 V and 24 V, with an impressive channel-to-earth isolation of 250 Vrms, CAT II. This isolation level signifies a robust protection for your signals, enhancing the safety and reliability of your application. The module’s output voltage capacity ranges from 5 VDC to 30 VDC, accommodating a variety of industrial applications.
One of the standout features of the NI-9474 is its maximum update rate of 1 us, facilitating high-speed sourcing digital output, which is essential for applications requiring rapid response times and precise control. Despite its high performance, the module maintains a low output impedance between 0.07 Ω to 0.13 Ω, ensuring efficient power delivery to connected loads.
To facilitate installation, the NI-9474 requires specific accessories depending on the terminal type chosen. For the Screw Terminal version, the NI-9927 Backshell Connector Kit is necessary, while the Spring Terminal version requires the NI-9981 Backshell Connector Kit. It’s important to note that the module does not come with a conformal coating, which may be a consideration for applications in harsh environments.
In summary, the NI-9474 module offers a versatile and high-performance solution for digital output needs, with its rapid update rate, high voltage capacity, and robust isolation. Whether for industrial control, automation, or research applications, it provides reliable and precise control, making it an essential component of any CompactDAQ or CompactRIO system.
