Description
The NI-9474 is a C Series Digital I/O module, identified by part numbers 779003-01 and 783908-01, designed for high-speed digital output applications. This module offers 8 channels of sourcing digital output, with each channel capable of operating at logic levels of 12 V and 24 V digital I/O. It features a maximum update rate of 1 μs, ensuring rapid data processing and control tasks.
With its spring terminal design, the NI 9474 module can handle an output capacity ranging from 5 VDC to 30 VDC, and it supports a continuous output current of 1.0 A per channel. This makes it suitable for driving a wide range of devices directly. The module’s output impedance ranges from 0.07 Ω to 0.13 Ω, and it is capable of withstanding transient overvoltage protection of 2,300 Vrms between output channels and backplane, ensuring robust operation and safety in industrial environments.
For connectivity, the NI-9474 offers two options: a screw terminal (part number 779003-01) and a spring terminal (part number 783908-01), with respective weights of 5.3 oz and 4.9 oz. It is compatible with CompactDAQ and CompactRIO systems, providing flexible integration options for a variety of applications. The module’s channel-to-earth isolation is rated at 250 Vrms, CAT II, further enhancing its safety features.
Although the NI-9474 module is not conformal coated, it operates within a temperature range of -40 °C to an unspecified upper limit, indicating its suitability for harsh industrial environments. Required accessories for optimal use include the NI-9927 Backshell Connector Kit for the screw terminal version and the NI-9981 Backshell Connector Kit for the spring terminal version, ensuring secure and reliable connections.
