Functional description
Output Q changes its status; that is, 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
function when S or R = 1.
You set the current impulse relay with a signal at input S.
The output is set hi.
You reset the current impulse relay with a signal at input R.
The output is set lo.
