Hello,
I started my new job at a factory and I found that when I opened the PLC cabinet there are "ABB contactors" that are connected to the PLC. would you please explain to me how does the PLC interact with the contactors ? explain to me how they interact with the input and output of the PLC.
I will appreciate your time explaining that to me.
