The 8005 digital I/O interface provides 48 channels of buffered drive digital I/O emulating 8255 mode zero, which 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. Optional values are available.

The PIO-48.PCI digital I/O interface board contains 6 groups of eight-bit I/O ports, configurable as inputs or outputs to suit the automation task.

Sealevel’s SeaIO Classic software drivers and utilities make installation and operation easy using Microsoft Windows operating systems.
