Description
The NI-9474 is a high-speed sourcing digital output module that falls under the C Series Digital I/O category. It has two part numbers: 779003-01 and 783908-01, which correspond to different connectivity options. This model is designed to operate with CompactDAQ and CompactRIO platforms, providing flexibility in application.
The module features 8 digital output channels that support logic levels of 12 V and 24 V. It is capable of delivering a high update rate of up to 1 us maximum, making it suitable for applications requiring fast digital signal processing. The output voltage capacity of the NI-9474 ranges from 5 VDC to 30 VDC, allowing it to handle a variety of loads.
For enhanced safety, the module offers channel-to-earth isolation rated at 250 Vrms, CAT II. This feature ensures the protection of both the module and connected devices from potential electrical hazards. The device’s output impedance is specified between 0.07 Ω to 0.13 Ω, ensuring efficient signal transmission.
Connectivity is facilitated through two options: screw terminal (part number 779003-01) and spring terminal (part number 783908-01). However, it is important to note that the NI-9474 is not conformal coated, which means it may not be suitable for extremely harsh environmental conditions without additional protection.
To complete the setup, certain accessories are required. For the screw terminal version, the NI-9927 Backshell Connector Kit is necessary, whereas the NI-9981 Backshell Connector Kit is needed for the spring terminal version. These kits ensure secure and reliable connections for the module.
The description of the NI 9474 as an 8-Ch 24 V, 1 us, High-Speed Sourcing DO module succinctly encapsulates its primary characteristics and capabilities, highlighting its suitability for fast-paced and demanding digital output applications.
