The PCIe-DIO-24HC is an x1 lane PCI Express digital I/O board with basic DIO, Counter/Timers and interrupt generation capabilities. The card uses an 8255 compatible chip, providing 24 DIO lines. The DIO lines are grouped into three 8-bit ports: A, B, and C. Each 8-bit port is configured via software to function as either inputs or outputs. Port C is further broken into two 4-bit nybbles via software, configured as either inputs or outputs.

Each DIO line is buffered and capable of up to 32mA source/sink. The VCCIO logic level is globally configured via jumper selection as 5V or 3.3V. Also, ports A, B, C low nybble, and C high nybble are individually jumper configurable as pull-up or pull-down through 10kO resistor networks.

There are three 82C54 counter(s) that each include three 16-bit counter/timers factory configured in an optimal mode for use as event counters, frequency output, pulse width, and frequency measurement.

The card is 4.824 inches in length and 4.2 inches seated height. I/O wiring for this board is via a right angle 50-pin latching male header connector. A ribbon cable can be used to connect this card to termination panels.

Accessories

Available accessories include a broad range of ribbon cables, screw terminal boards and optically isolated adapters and DIN-rail mounts for a variety of quick and easy connectivity options. Use ribbon cables with a female header on one end and a 50-pin female edge connector on the other to connect with industry standard solid state module racks.

SOFTWARE

The card comes with a free DOS/Linux/Windows (XP and newer) software package containing drivers, utilities, a graphical settings program to help configure option jumpers etc., and sample programs (with source) in Visual Basic, C#, Delphi, and Visual C++ for Windows. Linux support includes basic Comedi and direct-register source with tips on using the card from Python and other modern environments. Our Windows-standard DLLs can be used from all the most popular application programs including LabVIEW and even most “office applications”. Embedded OS support includes XPe, all flavors of Windows Embedded Standard, and more…including VxWorks and QNX.
