National Instruments USB-6212

The National Instruments USB-6212 is a versatile multifunction I/O device designed for a wide range of data acquisition applications including testing, control, and design. This device features two 32-bit counters and supports digital input, digital output, and analog input, making it suitable for field monitoring, embedded OEM projects, in-vehicle data acquisition, and portable data logging. The USB-6212 offers various connector options, including SCSI (part number 780169-01), screw terminal (part number 780107-01), and BNC (part number 781003-01). Additionally, the OEM Bus-Powered / Board Only version is available under part number 197504-03, with a pack of ten available as part number 780171-01.

Equipped with an integrated amplifier designed for rapid settling times at high scanning speeds, the USB-6212 ensures accurate and reliable data collection. Its signal streaming technology, similar to Direct Memory Access (DMA), facilitates bidirectional high-speed data streaming over USB, enhancing data transfer efficiency. The device connects effortlessly to a host computer through a USB 2.0 Hi-speed or full-speed interface, operating within a voltage range of 4.5V to 5.25V and handling a maximum inrush current of 500mA.

The analog input section supports 16 single-ended or 8 differential channels with 16-bit resolution, featuring a commendable common-mode rejection ratio (CMRR) of 100 dB and input ranges from -10 V to +10 V, ensuring reliable measurements in noisy environments. On the analog output side, the USB-6212 provides two channels with 16-bit DAC resolution, capable of delivering output ranges from -10 V to +10 V with overload protection up to ±30 V, all at a maximum update rate of 250 kS/s per channel.

Robustly built to meet multiple safety standards including IEC 61010-1, EN 61010-1, UL 61010-1, and CSA C22.2 No. 61010-1, the USB-6212 operates reliably in industrial conditions with an operational temperature range of 0°C to 45°C. Its outstanding input/output characteristics include minimal crosstalk (-90 dB for non-adjacent channels), low output impedance (0.2 Ω), and high input impedance (>10 GΩ), complemented by high-speed data transfer capabilities and an impressive timing resolution of 50 ns. The USB-6212 is backed by a three-year warranty and comprehensive user and maintenance manuals are available for download.
