The interval operational circuit of starting time delay

Published:2011/7/5 20:12:00 Author:Borg | Keyword: operational circuit, time delay | From:SeekIC

Working process: the power supply switch of QS is closed first, then the hand switch S is closed. At this moment, M is not starting immediately, but the relay 1KT is getting power and the timing is starting, when it is the regulated time of 1KT, its delaying contactor is closing, when the time relay coil of 2KT gets power and is starting to time, the coil of the AC contactor KM is getting power, the main contactor of KM is taking action, M is starting. After some time, the contactor of 2KT is taking action, the relay K is pulling in, and the normally open contactor is cut off.
