  • The PCIe-DIO-48S is a 48 channel PCI Express (PCIe) card designed for use in a variety of digital I/O applications. It uses the high speed PCI Express bus to transfer digital data to and from the card. The digital I/O is compatible with 8255 PPI (mode 0), making it easy to program. This also allows for simple and trouble-free migration from other ACCES PCI digital I/O cards . The card features a x1 lane PCI Express connector which can be used in any available x1, x2, x4, x8, x12, or x16 PCI Express expansion slot.

    Change of State Detection allows the PCIe-DIO-48S to interrupt the host computer when an input changes state.

    The PCIe-DIO-48S Features Include:
    • 48 channel high-current TTL digital I/O lines
    • Change of State (COS) detection and interrupt capabilities
    • Compatible with industry standard 8255 PPI
    • Two 50-pin male headers with 24 digital lines each
    • User interrupt pin on each DIO connector
    • All 48 digital I/O lines buffered with 32mA source / 64mA sink current capabilities
    • Four and eight bit ports independently selectable for inputs or outputs
    • 5V VCCIO (3.3V optional)
    • VCCIO available to the user on each I/O header
    • Compatible with industry standard I/O racks like Grayhill, Opto 22, Western Reserve Controls, etc.
