Hi sir I have a doubt, Limit switch gives digital signal to PLC. On other hand PLC gives a analog signal to vary the speed of the lift right? Correct me if iam wrong
Sir that's k.but temperature variations ah vachi 700'c reach aana udane plc kku input pogum and then output burner off seira mathiri thana set panrom. and ithulaiyum operation break or make thana aguthu 🙄🙄🙄. I say anything wrong and clearly my doubt sir
SMPS - Switched Mode Power Supply. It converts 230V AC into 24V DC. If PLC works with 230V AC, you don't need SMPS. If PLc is operating with DC then you need SMPS for 24VDC.
