DESCRIPTION
10Pcs 1 Channel DC 3V/3.3V Relay Power Switch Module with Optocoupler Relay Modu
- 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-
