Description
The NI 9474 model, specified by part numbers 779003-01 and 783908-01, falls under the C Series Digital I/O category. This module is designed to offer high-speed sourcing digital output, specifically providing 8 channels with a notable update rate maximum of 1 us. It is compatible with both CompactDAQ and CompactRIO platforms, ensuring versatile applications in various systems.
With its capacity to handle 12 V and 24 V logic levels, the NI 9474 ensures robust performance across a range of digital systems. It supports an output voltage range from 5 VDC to 30 VDC, catering to a broad spectrum of industrial requirements. Furthermore, each of the 8 digital output channels is characterized by a channel-to-earth isolation of 250 Vrms, CAT II, enhancing system safety and reliability.
Connectivity with the NI 9474 is facilitated through either Screw Terminal (779003-01) or Spring Terminal (783908-01) options, allowing for flexible integration into existing setups. Despite not being conformal coated, the module maintains a sturdy build. It is also compatible with NI LabVIEW software, simplifying the development of custom applications and interfaces.
For optimal functionality, the module requires specific accessories: the NI-9927 Backshell Connector Kit for screw terminal configurations and the NI-9981 Backshell Connector Kit for spring terminal configurations. Its output impedance lies between 0.07 Ω to 0.13 Ω, and it can continuously deliver 1.0 A per channel, with a transient overvoltage protection of 2,300 Vrms.
The module’s weight varies slightly between 4.9 oz for the spring terminal version and 5.3 oz for the screw terminal version. Designed to operate within a temperature range of -40 °C to +70 °C, the NI 9474 ensures reliable performance under a broad array of environmental conditions, making it an ideal
