- This video describes How PLC field inputs and outputs are scanned or read and write operation is performed on Digital Input and output cards? and what is inside circuitary of digital cards. The field input output supply voltage and wiring has been explained in this video @dineshdiwani
This video also describe opto couple device and safety features, which is widely used in input output cards. Field communication system and how there input output card shares or send information to PLC DCS, addressing, and information back to output cards have been explained.

Rack type plc, bus type plc पर वीडियो बनाइए
Knowledgeable sharing
Thank you ...Do subscribe
Keep it up sir
Whether there is universal analog IP card, which can accept RTD and 4 to 20mA input.(Universal input card ).
Yes it is there which accepts all kind of inputs. You have to do hardware configuration for which input will be Connected at which channel
Sir please make video on P&ID diagram
Sure...
Make a video on sinking & sourcing concept of PLC
Sure.. thank you
Bro....If u control 24 volt DC so provide 0 volt on comon terminal it's called source type ......and if u control 0 volt and provide 24 volt on comon terminal so it's called sinking ..
@@Anil-jq4mn when you consuming current you sinking ... When you supplying current you sourcing...simple
Sir plz start online course for beginners sir
All my videos are for beginners who just entered industries and started their careers.If you are upto any specific topic please mention.
Please make video on PLC specifications given in its sheet
Sure.. noted.. next will be on Foundation Field Bus
Sir could you tell me। What is potential free contact?
Which has no potential or voltage w.r.t earth or ground.
@@dineshdiwani पर सर यही बात तो समझ नही आती है। कॉन्टैक्ट बनेगा तो बिजली पास होगी। बिना वोल्ट के कैसे स्विच संभव है
@@SantoshSingh-nm1pe इसीलिए इनपुट पर जैसा वोल्टेज रहेगा वैसे आउटपुट पर रहेगा। चाहे वो AC हो या DC.. बस करंट रेटिंग से लिमिट में होना चाहिए। इसीलिए पोटेंशियल फ्री है।
@@dineshdiwani Sir, if I am right, in this, u mean to say that these contacts are limited by current ratings and that's why they are called potential free,
Where as for current to pass, a potential has to be applied more than the ground, else job is not done, no?
@@SantoshSingh-nm1pe they are free from potential or voltage..so whatever you pass it is passed as it is.
Sir G120 drive ke peramerter kese dalte hai
There may quick manu option.. start entering motor name plate parameters and then performs auto tuning... Then program PLC or DCS interface signals
