Automation Controllers and Gateways

SEL Programmable Automation Controllers (PACs) are built for utility and industrial applications. They provide rugged and reliable I/O solutions at an economical price. SEL PACs are hardened to meet stringent IEEE and IEC tests for harsh environments, and all are backed by SEL’s no-questions-asked, worldwide, ten-year product warranty.

Microprocessor-based relays and controllers have information that people and organizations want, including relay operations, metering, event reports, self-test status, power quality reports, demand reports, and equipment maintenance reports. From the beginning, SEL has offered easy ways to get this information from the relays and controllers to the users. Today, we offer technologies, products, systems, and services that address the entire application spectrum, from communicating with a single relay to integrating and automating the metering, control, reporting, and protection for a large system.
