National Instruments USB-6218 Multifunction DAQ Device
The National Instruments USB-6218 (Part Numbers: 781005-01, 196203-01, 779678-01, 780106-01, 196203-01, 194710C-01) is a flexible, isolated, multifunctional DAQ device intended for a range of industrial uses. Due to its many features, which include digital input/output, analog input/output, and counters, it can be used for a variety of applications, including portable data logging, field monitoring, embedded OEM, in-vehicle data acquisition, and academic purposes.
The difference between the part numbers for this device is that part number 779678-01 is an isolated driver, part number 196203-01 is an OEM board-only kit, and part number 780106-01 is designed for Linux and Mac. The 16-bit analog input resolution of the USB-6218, which supports up to 16 differential or 32 single-ended channels, is one of its standout features. It guarantees fast data capture with a maximum sample rate of 250 kS/s per channel.
With a timing resolution of 50 ns and timing accuracy within 50 ppm of the sample rate, the device stays accurate. With overvoltage protection up to ±30 V when the device is powered on, the USB-6218 supports numerous input ranges from ±0.2 V to ±10 V to suit a variety of input signals. Its input impedance is also greater than 10 GΩ, which guarantees minimal signal distortion. The device has two 16-bit channels with a maximum update rate of 250 kS/s each for analogue output. With a low output impedance of 0.2 Ω and overdrive protection up to ±30 V, the output ranges encompass ±10 V. As a result, output signals are reliable and accurate.
The USB-6218's adaptability also extends to the digital I/O and counter functionalities. It makes a variety of control and monitoring tasks easier with its two 32-bit counters and digital input and output capabilities. The USB-6218's isolation capabilities are a key feature; it provides 60 V CAT I isolation for increased precision and security. This guarantees dependable functioning in difficult settings as well. The NI-DAQmx driver and configuration tool are included with the device to simplify setup and operation and to speed up measurements and configuration.
A standout feature of the USB-6218 is its signal streaming technology, which allows for fast, bidirectional data streaming over USB that is comparable to DMA. For real-time applications, this guarantees effective data transfer.
