4 CHANNEL RELAY WITH ULN2003
This board is containing 4 channel relay which is operated by ULN2003 driver. This board is used in home applications and industrial purpose and many others. Input signals are given by microcontroller.
By using ULN2003 it can eliminate sudden voltage spike seen across an inductive load when its supply current is suddenly reduced or interrupted because there is a flyback diode which tack care of that.
• This Board can be used to Control Solenoids, Motors, Lamps etc.
• Input Logic -5v level from MUC.
• Interfaced with ULN2003.
• Input Pin connected to Burg stick.
