The NI-9474 is an advanced module designed for digital output applications, featuring part numbers 779003-01 and 783908-01. This module falls under the C Series Digital I/O category, offering high-speed sourcing capabilities.
The NI-9474 is equipped with 8 sourcing output channels, supporting a voltage capacity range from 5 VDC to 30 VDC. It is characterized by an impressive update rate maximum of 1 us, ensuring rapid signal processing for demanding applications.
Channel-to-earth isolation is rated at 250 Vrms, CAT II, providing a robust safeguard against electrical noise and potential damage. For connectivity options, the module offers flexibility with screw terminals (part number 779003-01) and spring terminals (part number 783908-01), catering to different wiring preferences.
Compatible platforms for the NI-9474 include both CompactDAQ and CompactRIO systems, making it a versatile choice for various data acquisition and control applications. Despite its advanced features, the module is not conformal coated, indicating a preference for use in controlled environments.
To ensure optimal performance and reliability, the module requires accessories such as the NI-9927 Backshell Connector Kit for screw terminal connections and the NI-9981 Backshell Connector Kit for spring terminal connections. The output impedance range is specified between 0.07 Ω to 0.13 Ω, and it can handle a continuous output current of 1.0 A per channel.
In summary, the NI-9474 module offers a powerful, high-speed sourcing solution for digital output needs within CompactDAQ and CompactRIO systems, featuring robust channel-to-earth isolation and flexible connectivity options.
