Description
The NI-9474 is a product that falls under the C Series Digital I/O category, designed to be compatible with both CompactDAQ and CompactRIO platforms. This module is identified by its part numbers, 779003-01 and 783908-01, catering to different connectivity requirements.
It is equipped with 8 digital output channels, supporting 12 V and 24 V logic levels, making it versatile for a range of digital I/O applications. The channels offer a channel-to-earth isolation of 250 Vrms, CAT II, ensuring safety and reliability in operation. The NI-9474 is capable of handling output channel capacities from 5 VDC to 30 VDC, with a maximum update rate of 1 us, allowing for rapid responses in control applications.
Connectivity is provided through either a 10-position Screw Terminal (779003-01) or a 10-position Spring Terminal (783908-01), giving users flexibility in wiring and connections. Despite its advanced features, it is important to note that the module is not conformal coated, which may affect its use in certain environmental conditions.
The module requires specific software for operation, namely NI LabVIEW, which facilitates programming and integration into larger systems. Additionally, users must procure certain accessories for optimal utilization, including the NI-9927 Backshell Connector Kit (Screw Terminal) or the NI-9981 Backshell Connector Kit (Spring Terminal), depending on the chosen connectivity option.
Finally, the NI-9474 boasts an output impedance range of 0.07 Ω to 0.13 Ω and is capable of delivering a continuous output current per channel, ensuring efficient power distribution and signal integrity across all applications.
