Specifications

PCI board with 24 digital I/O, High output drive (64 mA sink/15 mA source). An 82C55 chip provides the 24 I/O lines on three 8-bit ports (A, B and C), C port can be divided into two 4-bit ports (C-HI and C-LO), DB37 port of 37 pins.

The PCI-DIO48H is a high-density digital I/O card compatible with PCI. The PCI-DIO96H offers 48 bits of digital I/O. Provides 24-bit I/O groups based on 82C55, mode 0. Each group provides an A port and an 8-bit B port as well as an 8-bit C port that can be divided into 2 4-bit C ports: Puerto C-Hi, Puerto C-LO.

The card provides a discrete logic emulation of the 82C55 mode 0, but offers an output capacity of high digital output current (64 mA sink, 15 mA source). This mode 0 emulation is compatible with the 82C55.

The PCI-DIO48H is plug-and-play. It does not have switches or jumpers on the card. All the addresses of the card are configured by means of the software.

Features:

24 digital I/O bits
High current output (64 mA sink, 15 mA source)
