10Pcs 1 Channel DC 3V/3.3V Relay Power Switch Module with Optocoupler Relay Module Isolated Drive Control Board for IOT ESP8266 Microcontrollers Development Board 3v Logic Level Boards
ℹ
Products from the USA may come with an input voltage of 110V–120V, requiring a step-down transformer. Check the device wattage to select the correct power converter.
•3V 1 channel relay interface board support photocoupler isolation control,has the output signal indicator,the signal input port can connect SCM IO port, high level signal drive
•Relay board provides a single relay that can be controlled by any 3V/3.3V digital input from your microcontroller IO, support dual power supply input ensure high anti-interference ability,high reliability of photoelectric isolation protection
•3V/3.3V power relay module supports photocoupler isolation control and dual power supply input ensure high anti-interference ability. with diode continuous flow protection,response time is less than 20 milliseconds,long life of relay can be absorbed 100,000 times continuously.
•You can select whether the relay and the signal use the same power supply or not by removing the jumper caps on the pins. And It is better to share the same power supply, because that is more convenient for using.
•Relay Module: SRD-DC03V-SL-C; Channel: 1 channel; Working Voltage: DC 3-3.3V; Compatible Load: 10A 250VAC / 10A 30VDC; Single Socket Length: 7.5mm
