The NI-9474 is a high-performance module categorized under the C Series Digital I/O lineup, designed for seamless integration with CompactDAQ and CompactRIO platforms. This module is equipped with 8 Channels of digital output, capable of handling logic levels of 12 V and 24 V digital I/O, making it versatile for a wide range of application needs.
Each channel on the NI-9474 is safeguarded with channel-to-earth isolation rated at 250 Vrms, CAT II, ensuring robust protection against high-voltage transients. The module boasts an output voltage capacity ranging from 5 VDC to 30 VDC, accommodating a variety of load requirements. Furthermore, the NI-9474 can achieve an impressive update rate maximum of 1 us, enabling rapid response to control signals.
For physical connectivity, the module offers options for either Screw Terminal (779003-01) or Spring Terminal (783908-01), catering to different user preferences for wiring and maintenance. To complement these connectivity options, the NI-9927 Backshell Connector Kit is recommended for screw terminals, while the NI-9981 Backshell Connector Kit is suggested for spring terminals.
The NI-9474 is designed with an output impedance ranging from 0.07 Ω to 0.13 Ω and supports a continuous output current of 1.0 A per channel, ensuring efficient power delivery to connected loads. Enhanced safety measures include transient overvoltage protection, with the module capable of withstanding up to 2,300 Vrms between output channels and backplane, offering peace of mind in demanding industrial environments.
In summary, the NI-9474 combines robust electrical specifications with flexible connectivity and high safety standards, making it an ideal choice for engineers and professionals seeking reliable digital output solutions in their CompactDAQ or CompactRIO systems.
