PCI 16 Reed Relay Output / 16 Isolated Input Digital Interface (10-30V)



Optimized for sensing up to 24V inputs, the 8004H PCI digital I/O interface provides 16 optically isolated inputs and 16 Reed relay outputs. The inputs protect the computer 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. The relays are normally open, and close when energized.

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

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