The multi-function timing controller circuit is composed of the power supply circuit, pulse generator, delay control circuit and control implementation circuit, and it is shown in Figure 3-95. The power supply circuit consists of the step-down capacitor Cl, voltage regulator diode VS, rectifier diode VDl and filter capacitor C2. The pulse generator consists of the time-base ICl, resistors Rl, R2, potentiometer RP and capacitor C3. Delay control circuit consists of the decimal counting / pulse distributor circuit IC2, resistors R3, R4, diodes VD2-VD11, switches S1-S12. Control implementation circuit consists of transistor V, resistors R5, R6 and thyristor VT.
