Digilent PCI-DIO48H PCI Express Digital I/O Board

Digilent PCI-DIO48H PCI Express Digital I/O Board is a robust and versatile solution for digital interfacing in industrial and laboratory environments. The Digilent PCI-DIO48H board features 48 TTL-compatible digital I/O lines, organized into six 8-bit ports, each of which can be independently configured for input or output. Designed for high-current applications, the board supports sourcing up to 15mA and sinking up to 64mA per line, making it suitable for driving relays, LEDs, and other digital loads. The device includes advanced features such as change-of-state detection, event counting, and programmable pull-up resistors, enhancing utility in automation, monitoring, and control systems. With a PCI Express x1 interface, the PCI-DIO48H ensures fast and reliable communication with host systems, and the compact form factor allows easy integration into standard PC platforms. This board is ideal for applications requiring precise digital control, including embedded system development, automated testing, and process control.
