SeaI/O Products Win ECN 2005 Technology Award

Sealevel Systems’ SeaI/O family, a modular I/O system that offers selectable connectivity and a wide variety of I/O types for distributed control and data acquisition requirements, has been selected by ECN magazine as a 2005 Technology Award winner for boards and modules. SeaI/O was chosen for this honor as a result of editorial review and ECN reader inquiries of products featured in ECN during 2005.

SeaI/O modules connect to a host PC or controller via Ethernet, USB, RS-485, or RS-232, and multiple units can be daisy chained using convenient pass-through connectors to create a powerful distributed control and monitoring network.

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.

 Powerful software configuration & diagnostic tools
Address selectable via software or switch
 Easily daisy chain multiple units
 Selectable RS-485 line conditioning
 Flexible mounting options
 Modbus TCP and Modbus RTU compatible
