    sir…… generally the PLC output terminals are connected to heavy rating motors, equipment, ext.., but the working voltage of PLC is only 24v…. how it is saticefies

    sir…. the explanation given is easily understandable…. but i have a small doubt….is their any additional 230v direct supply is given to PLC module?? Iam using LX7 PLC module in its specification it mentionals it takes 12vdc inputs but iam not giving any 12dc but how it is possible…. any other internal components are their for 230vac to 24vdc and for 12dc..

    Thank’s Edvard
    I fully under stand the input’s can be either dc or ac my question is there a amperage limit rating on the dc or ac input? Is it possible to raise voltage on the Input Side with terminal’s? example T-1=12/vdc & T-2=24/vdc & T-3=36/vdc & T-4=48? And I fully under stand that the Out Put can be what ever is programed example line & load in a common house hold single pole switch. My question on Out Put is there a amperage limit rating? Thanks for your help I am a retired master electrician and am trying to find ways to switch 12 volt battery’s X 4 for 48/vdc but isolated by diodes from one other for protection from back feed is this program possible for the switching I purpose?
    Thanks Again

    great video.. i have a doubt that it is necessary that we keep in mind that whether we use toggle switch or spring loaded and what the major diff. btw these switches.

    thanks for this lovely course! still, i have one more little desire from you, buds. that’s a certain thing that i need an english subtitle. as being a non-english student, there is no way for me to understand completely these lessons given with an indian accent.
