I've been asked to write an essay where I will have to compare the construction and operation of two different types of stop/start/retain rela circuit for an AC or DC machine. I don't know how to go about it, how to start and I have no good circuits to compare. Can you help me please? Maybe some good websites that can explain me a bit more Thanks in advance
And got the following answer:
The only difference in a DC and an AC relay system you speak of is the voltage characteristics. One operates on AC current and the other operates on DC current. The system you speak of is a quite common relay circuit (primarily used to control motor starter contactors) which has two push buttons (one normally closed and the other normally open). The retain function is provided by a normally open contact on the relay itself. Thenormallyy open push button and the normally closed push button are both connected to the hot (or positive wire) of the circuit powering the relay. The other side of the normally open push button will connect to one side of the relay coil. The other side of the normally closed push button will connect to one terminal of a normally open contact on the relay, the other terminal of the normally open relay contact will connect the same side of the relay coil as does the wire from the normally opes push button. the other side of the coil connects to theneutrall (negative) wire. This completes the circuit. The operation is as follows: Pressing the normallyopenn (start)push buttonn will energize therelayy coil causing the relay to operate. This will lock-in the relay coil through the normally closed (stop) push button and the now closed normally open relay contact. The relay is now locked in (retained), and will remain so until the normally closed (stop) push button is pressed, This will open the push button contact and de-energize the relay coil. This removes the retained position of the relay. TexMav
