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
The dc ac relay work really nicely with unique applications that are distinct to power distribution and protection. The relays come with wide adjustment ranges using a scale which is easy to read either in 3 or 4 digits according to the model. These dc ac relay enable in growing the flexibility of your applications, decrease the overall power and maintenance costs. You can find relays which are utilised for general purposes which come in trusted styles with rapid replacement selections. And you can find models which are applied for industrial applications and heavier duty applications that operate on significant loads. These products are created to meet the lifetime industrial handle wants from the applications.
Their most current goods are the Time counter, Timer Delay, dc ac relay, Speedy Connect Couplings, Electronic Motor Couplings, Aluminum Couplings, Morse Couplings and numerous others. The website delivers a detailed description of each and every model in various categories of dc ac relay couplings and sensors. These items are incredibly beneficial for high-risk applications. The dc ac relay are also out there with options like several timing ranges and functions. The company is at present trying to find agents and dealers who can market and sell their factory produced solutions. They are usually on a lookout for developing new and more trustworthy merchandise based on the requirements and requirements from the business.
