Table 1. Portable USB DAQ for High-Voltage Digital I/O Selection Guide Hardware Description Common Applications National Instruments USB-9421, USB-9472, and USB-9481 are data acquisition modules with integrated signal conditioning. They provide plug-and-play connectivity via USB for faster setup and measurements, offering four or eight digital input or output channels specifically designed for monitoring and control applications. The NI USB-9421 digital input module accepts high-voltage levels between 11 and 30 V for direct connection to 24 V systems. The NI USB-9472 can source up to 30 V externally powered at 0.75 A of current per channel, and the NI USB-9481 uses electromechanical relays that can switch 2 A at 30 VDC and 1 A at 60 VDC. In addition, these modules include channel-to-earth ground isolation for safety, noise immunity and high common-mode voltage range. The USB-9421, USB-9472, and USB-9481 are ideal for monitoring and control applications where easy connectivity and portability are essential, such as: • Portable industrial monitoring and controlling motors, fans, pumps, relays, and limit switches • Data logging • Small form-factor applications • Embedded OEM applications • In-vehicle data acquisition • Academic lab use Software Description The USB-9421, USB-9472, and USB-9481 all use NI-DAQmx high-performance, multithreaded driver software for interactive configuration and data acquisition on Windows OSs. Use NI-DAQmx to test channels, generate code, and apply custom functionality to any of your measurements. All NI data acquisition devices shipped with NI-DAQmx also include VI Logger Lite configuration-based data-logging software. Recommended Accessories The USB-9421, USB-9472, and USB-9481 all have built-in screwterminal connectivity, so no additional accessories are required. The USB-9421 and USB-9472 are also available with D-Sub connector options that connect to the NI 9934 strain relief accessory, or any other standard 25-pin D-Sub connector.
