The 8018 Low Profile PCI digital I/O interface provides 24 channels of buffered drive digital I/O emulating 8255 mode zero. The board can be utilized for PC-based control and automation of equipment including sensors, switches, security control systems, and other industrial automation systems. 10K pull-up resistors are included and optional values are available. The 8018 contains three groups of eight-bit I/O ports. Each group is individually configurable as input or output to suit the automation task. The board is MD1 Low Profile and Universal Bus (3.3V and 5V) compatible and ships with a ribbon cable terminating in an industry-standard 50-pin IDC connector. The 8018 is for use in Low Profile PCI slots only. If you have a standard size PCI slot, order the 8018S. Sealevel's SeaI/O Classic software drivers and utilities make installation and operation easy using Windows 98, ME, NT, 2000, XP and Vista operating systems.
