SeaI/O Stack

SeaI/O modules provide powerful digital, analog, and serial expansion to any computer.  Connect to the host via wireless, Ethernet, USB, RS-485, or RS-232 to add the functionality required for your particular application.

Multiple units can be daisy chained using convenient pass-through connectors to create a versatile distributed control and monitoring network.  For ease of installation, multiple modules can be combined in a local stack or separated up to 4000 feet using the RS-485 Modbus RTU expansion interface.  Choose from a variety of I/O configurations, each designed for maximum flexibility and easy field wiring. For quick software implementation, application programs or third-party software can use Sealevel’s SeaMAX libraries or industry-standard Modbus protocol.
