3 Channel DC 3.3V 5V Relay Module Relay Expansion Board with Optocoupler Insulation for Arduino

Product Introduction:
1.Size:63*42*20mm
2.Power Supply Voltage:5V
3.Trigger Level:3V-7V trigger
4.Trigger Current:5mA
5.Control Voltage:AC 0-250V or DC 0-30V
6.Control Current:0-7A
7.Function:weak current control strong current (low voltage control high voltage;level signal control mechanical signal)
8.Using Method:this module is high level trigger,on-board pin marked GND(RGND)5V is respectively relay 5V power negative and positive;CH1,CH2,CH3 is control port,high level trigger;that is to say,after module power on,control port receives high level,the relay will be connected
