The SeaLINK® 8206FX digital I/O interface adapter provides 8 optically isolated inputs and 8 Form C relay outputs, which can be utilized for PC based control and industrial automation.

The 8 Form C relays support 2 Amp switch and carry current. Our unique serial string naming feature allows multiple USB digital I/O devices to retain their specific identity within the system. Onboard removable screw terminals are provided to simplify wiring connections. A DIN rail mounting option is available.

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

To simplify installation and configuration, a printed copy of the USB Digital I/O QuickStart Guide is included with all USB Digital I/O orders.

Important: If you are a previous customer of non-FX SeaLINK digital I/O adapters, you must update your SeaIO driver for proper operation of this 8206FX module. Please read this Support Article for details.
