PCI-DIO24 Series

More Info

The PCI-DIO24 Series are low-cost, 24-bit, logic level digital I/O boards for PCI bus compatible computers. Each board is based on the industry standard 82C55 chip, and the 82C55 I/O pins are brought directly to the board’s I/O connector. The 82C55 is a powerful 24 bit chip and functions as two 8-bit ports, (Ports A and B) and a third 8-bit port (Port C) that may be further divided into two 4-bit ports (Port C-HI and C-LO). The CMOS outputs of the 82C55 are suitable for driving a wide array of logic devices.

The PCI-DIO24 Series is connector and software compatible with Measurement Computing's highly popular ISA based CIO-DIO24 Series boards as well as a host of other 8255 based boards from other vendors. The board is also supported by the same wide variety of external relay and solid state I/O module racks as the CIO-DIO24 boards.

The PCI-DIO24H provides a discrete logic emulation of the 82C55 mode 0, but offers significantly higher output drive capability (64 mA sink, 15 mA source). This mode 0 emulation is fully compatible with the 82C55, and code written for 82C55 mode based boards will function perfectly on the PCI-DIO24H.

The PCI-DIO24 Series is completely plug-and-play. There are no switches, or jumpers on the board. All board addresses, interrupt channels etc. are set by your computers plug-and-play software.
