โมดูลรีเลย์ 3 ช่อง เปิดปิดด้วย logic 3.3V-5V Relay 3CH module with optocoupler isolation fully compatible with 3.3V ESP32/ESP8266/STM

3-Channel Relay Module With Optocoupler Isolation Compatible 3.3V 5V Signal

 

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
