Distributed I/O

Expand the I/O of SEL relays and communications processors, reduce copper in substations by transferring I/O from remote locations over fiber, and provide electrical isolation to avoid ground paths and induced noise and interference.

Automation Controllers

These controllers provide advanced automation and control capabilities and extend the I/O of relays and communications processors.
