SERIAL 8 CHANNEL AC 230V SSR AND DIMMER BLUETOOTH INTERFACE

OVERVIEW

SERIAL 8 CHANNEL AC 230V SSR AND  DIMMER WITH BLUETOOTH INTERFACE


The board can be  used in application where dimming of  110-220v AC power is required like dimming of bulb or fan.The board can be control with Serial data from any microcontroller 0-100% dimming or ON/OFF control Main power(230v) completely isolated from  microcontroller.



FEATURES

  • Works on AC power supply 230V.
  • Load Capacity 12 Amp AC(Up to 2000 Watt)
  • Isolated from mains power
  • Works from any microcontroller.
  • Serial Control (TTL).
  • Simultaneous 8 load control with 0-100% dimming.
  • Act as 8 channel solid state relay with ON/OFF and  dimming.
  • Optional input for Microcontroller or Bluetooth, XBEE, and USB inteface pin TX,RX,5V,GND.

BTA12400 IC




Electrical Characteristics

  • Average Power Dissipation of 0.5W
  • Operating Temperature +120 degC
  • Holding Current  (maximum)-30mA
  • Latching Current(maximum)-60mA 

MOC 3021

It is a 6pin Random Phase optoisolators TRIAC  driver output

TRIAC
from Triode for Alternating Current, is a genericized tradename for an electronic component that can conduct current in either direction when it is triggered (turned on), and is formally called a bidirectional triode thyristor or bilateral triode thyristor.

Applications:
  • Solenoid/Valve Controls 
  • Static ac Power Switch
  • Lamp Ballasts
  • Solid State Relays
  • Interfacing Microprocessors to 115 Vac Peripherals 
  • Incandescent Lamp Dimmer
  • Motor Controls

Electrical Characteristics
  • Total Power Dissipation @ TA  is  25°is 4.4mW
  • Storage Temperature Range is -40 to +150 degC

Example
A100= load1 at 100% dimmer level.
A026=load1 at 26% dimmer level.
B065=load2 at 65% dimmer level.
C089=load3 at 89% dimmer level.
