Using the Reverse Function | Schneider Electric SR2MAN01 specification

Implementing a Basic Application

Using the Reverse Function

Description	The reverse function, noted i in the smart relay is used to obtain the reverse state of
	input I wired on the smart relay.
	To illustrate how this function works, we shall use a simple example:
