The National Instruments PCI-6520 is a high-performance digital I/O module designed for demanding industrial applications. This device features a locally available time base that functions as the internal clock, enabling precise timing for advanced electronics. With 16 channels offering ±30 VDC, it includes 8 source/sink input lines and 8 electromechanical relay outputs capable of handling up to 60 V. The PCI-6520 enhances measurement accuracy with a 100 MHz time base, providing testing frequencies that are up to five times more precise than previous models, allowing for rapid response times of 10 ns when triggered.

To maintain optimal performance and reliability, the PCI-6520 utilizes NI-MCal technology, which advances self-calibration standards and reduces the maintenance burden of deployed systems. This capability allows most multifunction I/O devices to operate with a two-year external recalibration cycle while ensuring tight measurement tolerances. It is important to connect all ground pins when interfacing the PCI-6520 with high-current loads to adequately distribute current and minimize potential issues on individual wiring connections.

This digital I/O module integrates seamlessly with the NI-DAQmx software driver, making it suitable for a wide range of applications. The PCI-6520 is compact in design, measuring 6.9 inches by 3.9 inches, and weighs just 0.33 lbs, ensuring flexibility in various environments.
