Description
The interface follows IEEE C37.94 at 64 kbit/s, and the terminal connects to the standard optical port of a multiplexer. Commands are input from protection terminal contacts and output as contacts at the far end of the line. The terminal is used in protection schemes with permissive or blocking signals, and for direct transfer tripping of a remote substation breaker.
