National Instruments PCI-6225

The National Instruments PCI-6225 (Part Number: 779295-01) is a highly versatile multifunction data acquisition device designed for industrial automation applications, catering specifically to the requirements of research, design verification and testing, manufacturing testing, and laboratory automation. This device provides an extensive array of features to facilitate dependable and cost-effective data acquisition solutions across various applications. The PCI-6225 supports up to 80 single-ended or 40 differential analog input channels with 16-bit resolution and a maximum sampling rate of 250 kS/s per channel, making it suitable for accurately measuring diverse signal types due to its multiple input ranges (-10V to +10V), high input impedance, and built-in overvoltage protection. For analog output, the device offers two channels at a resolution of 16 bits and can achieve an update rate of 833 kS/s, ensuring reliable signal generation through precise voltage control, low output impedance, and overdrive protection.

In addition, the PCI-6225 features 24 digital I/O channels, each programmable as either input or output with voltage protection capabilities up to ±20V. This flexibility enables seamless integration with external sensors and devices, enhancing overall system control. The device includes two 32-bit counters/timers that facilitate accurate timing measurements and control functions, such as frequency division, pulse generation, and edge counting, which are critical for synchronizing events in complex automation settings. Furthermore, external digital triggers allow for synchronization with other devices and the initiation of analog operations based on specified events. The PCI-6225 integrates effortlessly into existing systems, offering compatibility with PCI, PXI, and USB interfaces, and supports multiple data transfer modes, including interrupts, DMA, and programmed I/O to optimize data throughput and efficiency. With its compact dimensions of 3.8 in. × 6.1 in. and a weight of 0.23 lb., the PCI-6225 is a highly efficient solution for advanced data acquisition and control needs in industrial environments. The device is backed by a three-year warranty, and user manuals are available for download. For pricing information, please contact a sales representative.
