The 8004 PCI digital I/O interface provides 16 optically isolated inputs and 16 Reed relay outputs. The inputs protect the PC and other sensitive equipment from spikes and ground loop current that can be generated in industrial environments, while the outputs provide high quality, long-life, low-current (10 Watt maximum), dry contact switch closures. Reed relays are well suited for low current applications. The relays are normally open, and close when energized.

The inputs on the 8004 are rated for 3-13V. For 10-30V inputs, order the 8004H. For RoHS compliance, order the 8004-RoHS.

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