Product Introduction
The NI USB-6212 is a bus-powered USB multifunction data acquisition device designed for portable testing, laboratory measurement, industrial monitoring, automated validation, and embedded data acquisition. It combines analog input, analog output, digital I/O, counter/timer functions, triggering, and USB connectivity in one compact measurement platform.
The USB-6212 provides 16 single-ended or eight differential analog input channels with 16-bit resolution and an aggregate sampling rate of up to 400 kS/s. It also includes two 16-bit analog outputs, up to 32 digital I/O lines depending on the connector configuration, and two 32-bit counter/timers.
Product Overview
The USB-6212 belongs to the NI M Series multifunction DAQ family. It is designed for applications that require a combination of voltage measurement, waveform generation, digital control, event counting, encoder acquisition, and hardware triggering without installing an internal PCI or PCI Express board.
Its USB Signal Stream technology provides high-speed bidirectional data transfer between the DAQ device and a host computer. The onboard analog input amplifier is optimized for fast settling during multichannel scanning, helping maintain measurement accuracy when acquiring signals from several channels.
The USB-6212 is available in BNC, mass-termination, and screw-terminal versions. The selected version determines the physical connectors, digital I/O count, dimensions, and compatible cabling or terminal accessories.
