The National Instruments USB-6225 is a multifunction I/O device designed for a variety of applications. Manufactured by National Instruments, this device is known for its reliability and advanced specifications. The model USB-6225 is available under part numbers 779974-01, 779973-02, 779973-04, 779973-01, and 779974-04, ensuring a wide range of availability for replacement or new setups.
Featuring a 16-bit Analog-to-Digital Converter (ADC), the USB-6225 is capable of a maximum sample rate of 250 kS/s, whether operating on single or multiple channels. This high level of accuracy is maintained with a timing accuracy of 50 ppm of the sample rate. To ensure optimal performance, a recommended warm-up time of 30 minutes is advised, with a calibration frequency of at least once a year to maintain accuracy and reliability.
When it comes to input capabilities, the device boasts 80 analog input channels, which can be configured as 80 single-ended channels or 40 differential channels. The input voltage range is quite flexible, offering ±0.2V, ±1V, ±5V, and ±10V options, with a maximum working voltage of ±11V. This is accompanied by an input FIFO size of 4,095 samples and overvoltage protection for all analog input and sense channels, ensuring the device’s durability and reliability in demanding environments. The specified input current during overvoltage is ±20 mA max, providing an additional layer of safety.
In terms of output, the USB-6225 provides 2 analog output channels, with a DAC resolution of 16 bit. The maximum update rate is impressive, reaching up to 833 kS/s for one channel and 740 kS/s for both channels simultaneously. The output range is ±10 V, with an output impedance of 0.2 Ω, ensuring high-quality signal transmission. Furthermore, the device includes overdrive protection, safeguarding against potential damage from excessive signal levels.
In conclusion, the National Instruments USB-6225 multifunction I/O device is a high-performance, versatile solution suitable for a wide range of applications. Its robust design, combined with advanced technical specifications, makes it a valuable tool for professionals requiring
