Work of the circuit The circuit consists of power circuit, the input control circuit, timing circuit and output control circuit. (It is showed in picture 8-93.) Power circuit consists of Buck capacitor C6, discharge resistors R6, bridge rectifier, UR, filtering capacitor C5, C4 and Zener VS. The input control circuit consists of the piezoelectric ceramic BC on Electronic alarm clock, capacitor Cl, resistors Rl and transistor Vl. Timing circuit consists of Resistors Rl-R5, reset button, Sl, regular timing switch S2, capacitor C2 and C3, light-emitting diode VL and time -based integrated circuit IC. Output control circuit consists of transistor V2, the relay K, the diode VD and AC contactor KM.
