Comparator
Output y = a logical "1", if the analog
signal x > 0, i.e. is positive.
Threshold value switch 1/0
Outputs at y a logical "1" if x < S.
Simple changeover switch
The switch position is shown according to
the factory setting
(in this case, switch position 1 in the
default state on delivery).
Limiter
x is limited to the upper limit LU and the lower
limit LL and output at y.
The digital signals MLU and MLL have the
value "1", if the upper or lower limit is active.
