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 pulse relay with a signal at input S, i.e. the out-
put is set hi.
You reset the pulse relay with a signal at input R, i.e. the
output is set lo.
