Notice Please:
When the jumper cap connected, the relay working power supply will also as the signal power supply, when not connected, the relay and signal power supply is isolated.
【Optocoupler Isolator】 3V/3.3V power relay module supports photocoupler isolation control.
【High Level Trigger】The relay module is triggered by high level signal, which can be input from microcontroller IO.
【Jumper Caps】You are free to select whether the relay and the signal share the same power supply or not by removing the jumper caps on the pins or not. It is recommended to share the same power supply, because that is more convenient for using.
【30VDC 250VAC Load】The power switch is compatible with 10A 250VAC and 10A 30VDC load.
