Vogurtime 5V Relay Module with Optocoupler Isolation Support High and Low Level Trigger Relay Red Board (8 Channel 5V Relay)

Module Interface: 1.DC+: Connect the positive pole of the power supply 2.DC-: connected to the negative pole of the power supply3.IN1-IN8: According to the setting of each way, the corresponding relay can be controlled by high or low level.1.NO1--NO8: The relay normally open interface, the relay is suspended before the suction, and it is short-circuited with COM after the suction.2.COM1--COM8 relay common interface3.NC1--NC8: The relay normally closes the interface, and the relay is shorted to COM before the suction is closed.1.> S1-S8 are the high and low level trigger selections of relays 1 to 8 in sequence, 2.> com is shorted with low, the corresponding relay is triggered by low level, and when com is shorted with high terminal, it is triggered by high level.Relay version: 5vQuiescent Current: 5mAMaximum current:190mA Trigger current: 2-4mALow trigger voltage: 0-1.5VHigh trigger voltage: 2.5-5Vsupport@foxmail.com.Always at your service,-) '
