IDEC SmartRelay Manual
Functional description
Output Q changes its status, i.e. the output is set or reset,
with each 0 to 1 transition at input Trg and if the inputs S and
R = 0.
The signal at input Trg does not influence the special func-
tion when S or R = 1.
You set the current impulse relay with a signal at input S, i.e.
the output is set hi.
You reset the current impulse relay with a signal at input R,
i.e. the output is set lo.

**: Triggering signal is effective, because S and R = 0.
