A relay accomplishes this by using the 5V outputted from an Arduino pin to energize an electromagnet which in turn closes an internal, physical switch attached to the aforementioned higher power circuit. Undervoltage and Overvoltage shutdown. Using the 1M resistors as shown above gets you input voltage protection to +/-1000VDC, which is enough to connect 220V AC mains directly to an Arduino input pin to do zero-cross detection for high-power/low noise relay-switching on AC lines!Writing a zero-cross detection algorithm lets you switch the relay when the AC power is at ~0VDC, thereby reducing the wear-and-tear on your mechanical. The buffer capacitor. High is adjusted at 260V and low is adjusted at 160V or as per your requirement. For example setting the limit for the over voltage protection and under voltage protection value. When input voltage goes high then the relay will activated and also when the input voltage is below then required level then relay activated. Thus the relay energizes in two conditions: first, if the voltage at pin 3 of IC2 is above 6. Over Voltage Generator over voltage may occur during a load rejection or excitation control failure.
