In the following star-delta motor starting example, i use T1 as a delay in order to make sure that star contactor will be de-energised before delta contactor is energized. Even though i use electrical interlock circuitry to prevent short-circuit, i always prefer to provide also an electronic safety. Since response time of the PLC outputs is much faster than the response time of the contactor coils, T1 delay is required. Today i had a ca
