SSR 8 Channel MicroController/MCU Ac Programmable Light Dimmer Module Controller Board for Arduino Raspberry Compatible 50/60hz
8 Channel Ac Programmable Light Dimmer Compatible AC dimmable LEDs, AC LED dimmer
PRICE BREAKS - The more you buy, the more you save
Module contains 8 Triacs with zero-cross detector for programming the intensity of incandescent lamps, heating elements, AC LED dimmable bulbs or fan speed controlled through a micro-controller.
Working AC voltage 80v 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 131mm x 91mm (5.16inch x 3.58inch). Four mounting holes diameter 3.2mm (0.13inch).
Connected LOAD current for each channel 5A long-term.
NOT appropriate to change the brightness of fluorescent lamps !!!
For inductive load controlling must be connected RC snubber
Dimming control via firing angle method.
Warning: This project deals with AC electricity which is dangerous if you don’t know how to treat it safely.
You must treat electricity with caution!

can you advise if unit 8Channel AC LED BULB DIMMER 110V 220V SMART HOME ARDUINO RASPBERRY PROGRAMMABLE is better please.Can you also confirm if I need the 8 Channel Multiplexer (74HC4051) to connect two units to Arduino. If this is better can you send me link to information please.
Answer: Multiplexer hc4051 is designed for input. In your case, best solution is to use shift registers hc595. It need only 2 wires - data and clock.
