fs
Switch-on delay
The digital signal x must have the value "1" without any interruption
during the time T before output y changes to "1".
Switch-off delay
The digital signal x must have the value "0" without interruption
during the time T before output y changes to "0".
Delay (switch-on and switch-off)
PT1 element
Delay element, first order.
pxxxx = time constant
PT2 low pass

Analog adder can be activated
The following applies to I = 1 signal: y = x1 + x2
The following applies to I = 0 signal: y = x1

Switch symbol
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).
The digital signal x must have the value "1" without interruption
during time T1 or must have the value "0" during time T2 before
output y changes its signal state.
