4 CHANNEL AC LIGHT  TRIAC DIMMER 
CONTROL VIA I2C  PROTOCOL
 
Only 4 wires are  needed to control this board !

 
DEVICE FEATURES:

With this module  you can control the intensity of incandescent lamps,

LED  dimmable  bulbs, power heating elements or fan speed controlled through a microcontroller or Arduino/Raspberry boards.

Compatible with  any Arduino, Raspberry or microcontroller

Dimming method - leading edge

Working voltage -  110 or 240 VAC

Current per  channel - up to 3A

Compatible with  50Hz and 60Hz AC Line

AC Line  autodetect function

PCB dimensions -  140mm x 60mm

Distance between  holes: vertical 51mm, horizontal  131mm

Mounting holes  diameter: 3.2mm

100kHz I2C bus  interface

I2C bus pull up  switch on board

I2C device  address select switch on board

Can be connected  up to 8 devices on I2C bus (8  devices x 4 = 32 channels!!!)

50HZ LED - show  detected AC 50HZ Line

60HZ LED -  show detected AC 60HZ Line

BOTH LED Flashing - AC Line not detected

 

Microcontroller on-board. No programming required  !!!

 

PCF8574 is used  as I2C buffer

SDA and SCL I2C pull up  switch (pull upped with 5.6k resistors)

Note: 

I  recommend to use a  EMI filter with this device. Connect it before AC INPUT.

This board have pull-up switch  for  SDA and SCL lines.

I2C-bus must be  always pull-ups.

If you use more  than one device on  I2C-bus - one device must be pull-ups and others  not.
