DIGITAL I/O SOLUTIONS

Sealevel digital I/O solutions make interfacing to the real world easy. Whether you choose PCI, ISA, PC/104, USB, or our eI/O products, our software drivers and wide range of terminal blocks and cabling accessories simplify installation.

Check out our new SeaI/O family of digital I/O products. Choose from five I/O configurations, each designed for maximum flexibility and easy field wiring. Ordering options allow connection to the host device via Ethernet (Modbus/TCP), USB, RS-485 (Modbus/RTU), or RS-232 (Modbus/RTU). Up to 246 expansion modules can be daisy chained to the Base module to create a powerful I/O network.
