Example 11: The open/ close delay circuit is composed of two timers; output Y4 will have a delay
whether input X0 is On or Off.
Example 12: Extended timing circuit
In the circuit in the figure on the left, the total delay time from the moment input X0 closes to
the time output Y1 is electrified is (n1+n2)*T, where T is the clock cycle. Timers: T11, T12;
clock cycle: T.
