4 DIN RAIL Channel Ac Programmable Light Dimmer

Leading Edge Dimmer for resistive and inductive loads
Module contains four triacs with zero-cross detector for programming the intensity of incandescent lamps,
LED dimmable bulbs, heating elements or fan speed controlled through a micro-controller.
Working AC voltage from 80v to 240v.
Auto detect 50Hz or 60Hz.
Zero-Cross detection (with zero/cross output pin ZRC).
Compatible with any MCU or ARDUINO and RASPBERRY boards.
Device power supply - 3.3V and 5.0V.
Low voltage side and high voltage side is completely optoisolated.
Dimensions of the PCB 100mm x 72mm. Four mounting holes diameter 3.2mm.
DIN RAIL mountable.
Connected LOAD power for each channel 500W long-term and 1000W short-term.
Long-term current per channel - 2A.
NOT appropriate to change the brightness of fluorescent lamps !
Control dimming level 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!
NOTE: please observe the polarity of the network
