Example 10: Delay Circuit

X0
T10
When input X0 is ON, output coil Y1 will be ON at the same time due to the corresponding
normally close contact OFF makes timer T10 to be OFF. Output coil Y1 will be OFF after
delaying 100 seconds (K1000*0.1 seconds =100 seconds) once input X0 is OFF and T10 is
ON. Please refer to timing chart above.
Example 11: Output delay circuit, in the following example, the circuit is made up of two timers. No
matter input X0 is ON or OFF, output Y4 will be delay.
