AC Phase Control Circuit (Dimming Circuit)

For resistive and inductive loads with snubbers on board!

Module contains two Triacs with zero-cross detector
for programming the intensity of incandescent lamps, AC LED dimmable bulbs, heating elements or fan speed controlled through a micro-controller.

Working voltage from 110v to 240v.
Auto detect 50Hz or 60Hz.
Zero-Cross detection (with zero/cross output pin SYNC).
Compatible with any ARDUINO, RASPBERRY boards.
Low voltage side and high voltage side is completely isolated.
Dimensions of the PCB 110mm x 50mm (4.33inch x 1.97inch). Four mounting holes diameter 3.2mm (0.13inch).
Connected LOAD 2A long-term and 5A short-term.

Descriptions of pins:

GND -> ground of low voltage side
VCC -> device power, DC 5 volts
SYNC -> zero-cross detector output positive impulse (pulse length 200us)
CH1 -> triac gate input pin for 1 channel
CH2 -> triac gate input pin for 2 channel
CH3 -> triac gate input pin for 3 channel
CH4 -> triac gate input pin for 4 channel
AC INPUT -> AC voltage input 110/220
AC LOAD -> Connect your load here for 1ch, 2ch, 3ch and 4ch

NOT appropriate to change the brightness of fluorescent lamps !!!
