NI USB-6212 Description
The NI USB-6212 is a Data Acquisition (DAQ) device from National Instruments (NI) designed for high-accuracy analog and digital signal measurements. With a plug-and-play USB interface, this device enables flexible data acquisition for various industrial, research, and automation applications.
Key Features:
- 16-bit Resolution: Ensures high accuracy in signal measurements.
- Sampling Rate up to 400 kS/s: Allows fast data acquisition for real-time analysis.
- 16 Analog Input Channels:
- Single-ended (16 channels) or differential (8 channels) configuration for flexible measurements.
- 2 Analog Outputs: With 16-bit resolution for signal control.
- 32 Digital I/O Channels: For monitoring and controlling external systems.
- 2 Counter/Timer 32-bit: Supports frequency measurement, pulse counting, and process synchronization.
- USB 2.0 Connectivity: Simplifies integration with a PC without requiring external power.
- Compatibility with NI-DAQmx and LabVIEW: Enables more efficient data processing.
