On this slide are the diagrams showing the areas where isolators can be used to protect and provide safety. The isolator on the right colored in teal is used between the local micro and the HV equipment will help prevent high voltage transients and noise generated from the HV field equipment from being coupled back to the micro. The isolator between System X and the local micro is used for a few functions. Firstly, it is used to translate different operating logic voltages. So, if System X operates from a 5V supply and the local micro operates from a 3.3V supply, the isolator can harmonize the two systems by translating the voltages between them. Additional benefits of the isolator are to break ground loops and ignore common mode voltage. The two aforementioned isolators in combination with the isolator between the local micro and the human machine interface, typically a control panel with a touch sensitive LCD, help protect the operator from electrical shock.
