PCI Module, R-Series DIO

The NI PCI R-Series Digital I/O (DIO) Modules provide high-performance, FPGA-based digital input and output for PC-based test, control, and automation systems. Designed for applications that require precise timing and deterministic behavior, these modules enable direct, hardware-level control of digital signals. Built on the PCI Express architecture, R-Series DIO modules combine flexible digital I/O with reconfigurable FPGA technology, allowing engineers to implement custom timing, handshaking, and control logic directly in hardware. This makes them ideal for applications where standard software-timed I/O is insufficient. NI PCI R-Series DIO hardware is widely used in hardware-in-the-loop (HIL) simulation, industrial automation, aerospace and defense systems, embedded system validation, and advanced research environments. Their robust design and programmable architecture provide scalable and repeatable digital I/O solutions for demanding real-time applications.
