3V 1 Channel Relay Power Switch with Opto Isolation High Level Trigger
Optocoupler Isolator: 3V/3.3V power relay module supports photocoupler isolation control.
High Level Trigger: The relay module is triggered by a high-level signal(1.3V), which can be input from microcontroller IO.
Long Life: Fast response time less than 20ms and long lifetime up to 100,000 times snap action with diode freewheel protection.
