Description
The National Instruments USB-6225 is a multifunction I/O device that is designed to meet a wide range of automation and measurement needs. This device is equipped with 80 analog input channels, which can be configured as either 40 differential or 80 single-ended channels, providing flexibility for various application requirements.
The device boasts a 16-bit Analog-to-Digital Converter (ADC) resolution, ensuring high precision in data acquisition. It is capable of a maximum sample rate of 250 kS/s for both single and multiple channel configurations, offering efficient data collection for time-sensitive applications. The timing accuracy is guaranteed to be within 50 ppm of the sample rate, highlighting the device’s reliability in timing-critical operations.
Users can select from multiple input ranges, including ±0.2V, ±1V, ±5V, and ±10V, allowing for versatility in handling various signal levels. The maximum working voltage is rated at ±11V, providing a margin for signal fluctuations. Additionally, the device is designed with an input FIFO size of 4,095 samples, enabling efficient data buffering during high-speed acquisition.
To ensure durability and reliability, the USB-6225 is equipped with overvoltage protection for all analog input channels, safeguarding the device against unexpected voltage spikes. Furthermore, it includes 2 analog output channels with a 16-bit Digital-to-Analog Converter (DAC) resolution, facilitating precise control signals or generating specific waveforms as needed.
The USB-6225, with its part numbers 779974-01, 779973-02, 779973-04, 779973-01, and 779974-04, represents National Instruments’ commitment to providing high-quality, versatile, and reliable measurement and automation solutions.
