Description
The NI-9474 is a high-speed sourcing digital output module that belongs to the C Series Digital I/O category. The part numbers for this module are 779003-01 and 783908-01, indicating two different connectivity options: Screw Terminal and Spring Terminal, respectively. This module is designed to deliver precise and reliable performance with its 8 digital output channels, supporting logic levels of 12 V and 24 V digital I/O.
One of the key features of the NI-9474 is its channel-to-earth isolation rated at 250 Vrms, CAT II, providing enhanced safety and system reliability. The module is capable of handling an output capacity ranging from 5 VDC to 30 VDC, with an impressive update rate maximum of 1 us. This allows for high-speed operation in demanding applications.
Despite its advanced capabilities, the NI-9474 does not come with conformal coating. However, it does require specific accessories for optimal operation, including the NI-9927 Backshell Connector Kit for the Screw Terminal version and the NI-9981 Backshell Connector Kit for the Spring Terminal version. These accessories ensure secure and reliable connections.
The output impedance of the module ranges from 0.07 Ω to 0.13 Ω, and it can support a continuous output current of 1.0 A per channel. This combination of features makes the NI-9474 an ideal choice for applications requiring high-speed and high-quality digital output signals.
