Wiring circuit

This is the Simple Comparator for Over Voltages Circuit Diagram. Comparator is a device that compares two voltages or currents and outputs a digital signal indicating which is larger. It has two analog input terminals V_+, and V_-, and one binary digital output V_o,. The output is ideally. To maintain an alarm condition when an overvoltage transient disappears, add an SCR to the comparator diagram. For SCR operation, voltages to the comparator inputs are inverted. (B) The triple-voltage monitoring schema detects transient power-supply over-voltages.If excessive voltage momentarily appears at the 5, 12 and -12 V inputs, the LED for that schema lights and the beeper sounds for as long as the .
