Operating & trigger Voltage :
3V or 3.3V = Support High signal trigger only.
5V = Support Low signal trigger only.
12V =Support High / Low Signal Trigger (change with jumper cap)
Maximum Current Rating: 10A
Maximum Voltage Rating: AC 250V / DC 30V
Can control various appliances with large current
Can be controlled directly by microcontroller such as Arduino, 8051, AVR, PIC, DSP and ARM
Optocoupler isolation, drive capability, stable performance; trigger current 5mA.
2-8 ways Relay come with Opto-isolator
DC+ = DC Voltage input , 5V Module input voltage is 5V, 12V Module is 12V, 3V Module is 3V or 3.3V.
DC- = Ground
IN1 = Signal to trigger
NO1 = Normally Open Terminal
