Awesome but we want to some more about relay

So the photo electric switch uses lets say 24 volts i guessing via a transformer.

Why do the headlights on the car have to go through a Relay? Is it also due to higher voltage and safety?

@realpars

5 жыл бұрын

Hi there, in this video we have simplified the process of turning on and off the headlights of a car as an example for you to get the gist of the relay application. Actually, when you give the command to turn on the headlights in your car, this command goes over to the relevant ECU (which stands for Electronic Control Unit) in the car. ECU itself cannot send the voltage directly to different parts of the car such as the headlights, but instead, it gives the command to the relay which is associated with that part. That means it converts the voltage to the voltage level which is required by the headlight to be turned on.

Just wondering, if the headlight switch in a car is a 12v connection and the headlights circuit is also 12v - why would you need a relay? I have a very basic understanding and I thought relays were used to control hvac circuits with lvdc/ac to prevent serious electric shock?

@realpars

There are a couple of reasons that a relay is used. The main reason is that with higher-powered headlights, it is necessary to use a relay to separate the low-power switching circuit (what turns your lights on and off) and the higher-power circuit to the lights. Most auto headlight relays have two NO contacts so that both headlamps can be powered from one relay. This allows each headlamp circuit to be individually fused and isolated.

Are older PLC models any different than the ones in your videos?

@realpars

2 жыл бұрын

Great question! PLC programming with ladder logic has changed very little since PLCs first appeared in the 1970's. The software has improved dramatically as PC's became more powerful, and more graphical. But even more recently, most manufacturers have provided backwards compatibility with their instruction sets. I can upgrade most Siemens S7-300 programs to S7-1500 with not much effort. If you can program an S7-300, you can program an S7-1500, and vice versa. You may need to become familiar with a few differences in the software versions, but that is like learning a new version of Excel. Newer PLC's are faster, have more memory, and can handle more I/O than older PLC's, but they are essentially the same useful logic processors.

At RealPars.com you learn more than just programming when you you subscribe to RealPars.com. I'm eagerly awaiting level 9 videos.

So basically, relays (contactors) are used when we do not intend to directly switch OFF/ON high voltage and high current circuits (AC motors)? Because what you are implying is that direct control of high voltage/current circuits pose potential danger to safety of operators? Let's say we have an air handling unit with a single feed electric panel feeding two supply fans (Each with 10HP AC motors). Would a panel disconnect switch still be required if we can use 24 V switch to operate the motor contactors?

@realpars

2 жыл бұрын

You may have misunderstood the premise. High voltage, such as 440VAC that is used to feed a motor circuit, cannot be switched on and off by a pushbutton directly. The pushbutton does not have a power rating sufficient to do that. That would pose a significant safety risk. Instead, we can connect a pushbutton to a relay (motor start relay) that energizes a low-power 24VDC or 120VAC relay that is able to pull in a larger set of contacts (motor starter) to start the motor. To answer your second question, it is good practice (and usually required by local codes) to have a main disconnect for a control panel. Power disconnect switches are able to be de-energized and locked out to prevent safety issues. Relays are also invaluable to keep circuits separated (for example, 24VDC from 440VAC, or two different 24VDC circuits),l also for safety reasons.
