Work of the circuit The circuit consists of +12V power circuit, monostable circuit and relay control circuits. (It is showed in the picture 8-136.) Power circuit consists of power transformer T, rectifier diode VDl, VD2, three-terminal voltage regulator integrated circuit ICl and filter capacitor Cl, C2. Monostable circuit consists of potentiometer RP, diodes VD3, capacitors C3, C4, time-base integrated circuit IC2 and the normally closed contact relay Kl. Relay control circuits consists of resistors Rl, R2, relay Kl, K2, diodes VD4 and LED VL.
