This is ready breakout board with four (4) 5V activated relays, with 3 screw terminals for each relay (NO, NC, COM) and screw terminals for control signal from microcontroller such as Arduino. Each control signal is opto-isolated, protected. It even comes with activation LED indicator for each relay. Easy to use and suitable for beginner, and of course student too.
If you need to control AC or high current, high voltage load, this will be the perfect board.
Features:
5V 4 channels relay module
Configureable Activation Logic, High or Low, via mini jumper
Maximum Current Rating: 10A
Maximum Voltage Rating: AC 250V
Can control various appliances with large current and high voltage
Can be controlled directly by microcontroller such as Arduino, 8051, AVR, PIC, DSP and ARM
Build in 4 units of Opto-Isolator for extra isolation and protection to controller.
