YH2902A based multi-functional lighting control circuit with delay timing control

By the timing control modules YH2902A versatile multi-functional lighting control circuit YH2902A delay constitutes a versatile lighting control circuit delay. Where Rx=120kO, Cx=1pF, the t=1 / 1 (0.7 ~ 1) · Rx · Cx], then the delay of the circuit can realize 5 minutes, 15 minutes, 30 minutes or irregular four working process.
