National Instruments USB-6212 Multifunction I/O Device  

National Instruments' USB-6212 (Part Numbers: 781003-01, 197504-03, 780171-01, 780169-01, 780107-01, 198402B-03L, 197493B-03L, 190630B-01L) is a flexible, multipurpose DAQ (Data Acquisition) tool intended for a variety of test, control, and design uses. Because it has two 32-bit counters, digital input, digital output, and analog input, it can be used for a variety of applications, including field monitoring, embedded OEM, in-vehicle data acquisition, and portable data logging.

The USB-6212 is available in various connector types, including SCSI (part number 780169-01), screw terminal (part number 780107-01), and BNC (part number 781003-01). Part number 197504-03 describes the OEM Bus-Powered / Board Only version of the device, which can also be found listed as a pack of 10 (part number 780171-01). With its integrated amplifier, which is designed for quick settling periods at high scanning speeds, this device ensures precise and dependable data gathering. Furthermore, similar to DMA (Direct Memory Access), its signal streaming technology allows for bidirectional high-speed data streaming across USB, improving the efficiency of data transfer.

A host computer may connect to the USB-6212 seamlessly thanks to its USB 2.0 Hi-speed or full-speed interface. It is compatible with multiple systems since it runs between 4.5V and 5.25V input voltage range and 500mA maximum inrush current. Impressive capabilities are offered by the analog input section, which supports 16 single-ended or 8 differential channels with 16-bit resolution. It ensures reliable measurements even in noisy surroundings with its strong CMRR (Common-Mode Rejection Ratio) of 100 dB and numerous input ranges of -10 V to +10 V.

The USB-6212 has two channels with 16-bit DAC (Digital-to-Analog Converter) resolution on the analog output side. With overload protection up to ±30 V, it covers output ranges from -10 V to +10 V and has a maximum update rate of 250 kS/s per channel. The device satisfies multiple safety standards, such as IEC 61010-1, EN 61010-1, UL 61010-1, and CSA C22.2 No. 61010-1, and functions reliably in industrial settings. Its operational temperature range is 0°C to 45°C. The USB-6212 has exceptional input/output properties, including minimal crosstalk (-90 dB for non-adjacent channels), output impedance (0.2 Ω), and input impedance (>10 GΩ), along with high-speed data transfer and exact timing resolution of 50 ns.
