    Help on Identifying a PLC and electro-magnetic commercial start/stop/retain relay system

    So for one of my tasks on my assessment I've bee asked this question: To ensure that the conveyor system is safe and complies with legislation, compare the construction and operation of an elecro-magnetic relay system with a PLC system that controls a 3-phase contactor. Include appropriate...

    Safety relay circuit diagram for a robot cell. Please Help

    That's mad, even though I watched the whole video I couldn't even contemplate how that works. Seems like you'd need ear defenders being in there all day doing scientific equations

    Safety relay circuit diagram for a robot cell. Please Help

    I didn't realize that they played such a crucial part in them sort of systems, it's fascinating how it all works! I'm currently doing a course in electrical and mechanical engineering. I work in the mechanical side of things so I though that I'd enjoy that more, but finding out how all the...

    Safety relay circuit diagram for a robot cell. Please Help

    Going threw it in order defiantly helps. I didn't think about relays sticking, it makes complete sense to me why this system is used now and I'm not going lie I didn't think that I'd get my head around it. Thanks, I really appreciate your help yet again :)

    Safety relay circuit diagram for a robot cell. Please Help

    Ah okay I get it so its only the relay system used for the robot cell as mentioned lol! I sometimes get stuff like this warped around my head my own fault for not reading it correctly and jumping to conclusions. It definitely makes a lot more sense knowing that they are all relays. SO the EQP...

    AC to DC motor thyristors speed and direction control

    Thanks! my course is quite basic so it's just touching on all the mechanical and electrical applications and devices so i wont need to go in to that amount of detail; for the time being any way. You have a vast amount of knowledge on this subject and I now understand this system to a level that...

    AC to DC motor thyristors speed and direction control

    Would the supplied image be the correct way to show this? I take it that it wouldn't be required of me to show where the gates of the thyristors were connected up to as long as i put a explanation about this? I'm not able to use a H- bridge system as it is part of this as it is part of my next...

    AC to DC motor thyristors speed and direction control

    Thank you! I have found a direction control circuit diagram and now see how that works. its surprisingly hard to find if you don't know what to search. However I can't find a diagram that both controls speed and also the direction, so to answer this question I'm going to have to use 2 different...

    AC to DC motor thyristors speed and direction control

    So i have been given this question: You have also been asked to produce a circuit design that can control the speed and direction of a conveyor with a AC to DC motor thyristor system. What are the the operational features (how it works with speed and direction circuit diagram/s) I am really...
