The 3093 ISA digital I/O interface card provides 32 optically isolated inputs and 32 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 3093 are rated for 3-13V. For 10-30V inputs, order the 3093H.

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.
