Wireless remote control/touch dimming circuit (RCM1A/RCM1B)

Relevant key device information applied in this article: RCM1B CS7232 radio remote control/touch dimming circuit is an incandescent lamp dimmer switch composed of radio remote control component RCM1A/RCM1B and touch dimming integrated circuit CS7232 as the core. It can be used to control chandeliers and table lamps. and wall lamps, etc., which are compact in size, easy to use, and work stably and reliably. CS7232 is a CMOS integrated circuit used for dimming control of incandescent lamps. It controls the light brightness by controlling the conduction angle of the triac. It has the characteristics of low power consumption, multi-function, and high control sensitivity. It is suitable for AC 220/ Incandescent lamp circuit powered by 115V, 50/60Hz power supply. CS7232 adopts DIP-8-pin plastic package. Its pin arrangement and internal circuit block diagram are shown in the figure below.
