Light Controller Circuit Diagram using HT2040A IC
Light Controller Circuit Diagram using HT2040A IC - This schematic Light Controller Circuit using a low cost, low power CMOS LSI chip – HT204oA which provides 4 SCR outputs to control the lamps that can display 10 different lighting patterns appropriate to the input keys. It might be designed for use in Christmas lighting.
Up to 23 patterns can be programmed inside this circuit (12 patterns and 10 pre-programmed groups are provided by default). The IC substrate should be connected to VDD in the PCB layout artwork.
Note that R = 47KW/0.5W when the AC power supply is 110V and R = 91KW/1W when the AC power supply is 220V.
Or you might need to see the HT2040A datasheet regarding this Light Controller Circuit Diagram.
