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)

I2C Device Address select switch

Table show device addresses. Default address - 0x27 or 0x3F

I2C-Bus Address scanner for Arduino

Arduino demo sketch for I2C Slave address 0x27

Arduino demo sketch for I2C Slave address 0x3F

How to control board via I2C protocol? Only with 3 bytes!

Wiring diagram in high resolution

Note:

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

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.
