Enabling the Energy Evolution

Sealevel reinvented the industrial I/O and computing industry with the first RS-422/485 communication adapter for the IBM PC. Since 1986, Sealevel has continued to redefine design, engineering and manufacturing for industrial computers, synchronous serial, Ethernet serial servers, and IoT hardware and software.

We are committed to a first-in-industry lifetime warranty on I/O and long-term availability of all products, beyond the life of your mission.

Sealevel’s team is excited to be at the forefront of control across the energy industry: from ruggedized computers to support wind turbines to drone I/O for power line inspection to touch panel PCs for oil and gas environments.
