Defines the electrical interface characteristics (e.g. signals, impedances, and the like) which have to be met at the shared boundaries. It is one of a series of Standards applicable to telecontrol equipment systems. This Standard is identical with and has been reproduced from IEC 60870-3:1989.

This series of standards applies to telecontrol equipment and systems with coded bit serial data transmission for monitoring and controlling geographically widespread processes.
