Alinan 10pcs 1 Channel 3V Relay High Level Relay Power Switch Board, Optocoupler Module Opto Isolation High Level Trigger for IOT ESP8266 Development Board
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. Photocoupler Isolation Control High Level Trigger Long Life Specifications Working Voltage: DC 3-3.3V Load: 10A 250VAC / 10A 30VDC Working Current: 65mA Trigger Current: 3mA Load Current: 10A max Single Socket Length: 7.5mm Response Time: <20ms Jumper Caps JP1 is used to connect VCC of the signal terminals and V+ of the relay. JP2 is used to connect GND of the signal terminals and V+ of the relay. The high- level signal that over 1.3V to IN can trigger the relay.
Product Features
- High ReliabilityDouble power selection design anti-interference ability is strong, photoelectric isolation protection of high reliability.
- 30VDC 250VAC LoadThe power switch is compatible with 10A 250VAC and 10A 30VDC load.
- Optocoupler Isolator 3V/3.3V power relay module supports photocoupler isolation control.
- High Level TriggerThe relay module is triggered by high level signal, which can be input from microcontroller IO.
- Jumper CapsYou 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.
