2. Use Low Level Trigger
When ¡°IN¡± input Low Level Signal, the ¡°NO¡± connect with ¡±COM¡±
When ¡°IN¡± input High Level Signal, the ¡°NC¡± connect with ¡°COM¡±
3. High or Low Level Trigger Select
Jumper connect with L, Low Level Trigger
Jumper connect with H, High Level Trigger
Package ：
2* 12V 1 Channel Relay Module
This Relay Board provides a single relay that can be controlled by any 12V digital output from your microcontroller.
The module uses genuine quality relay, normally open interfaces , Maximum load: AC 250V/10A, DC 30V/10A.
SMD optocoupler isolation, strong driving capability, stable performance; trigger current 5mA.
The interface design of human nature, all interfaces are available through a direct connection terminal leads, very convenient.
These 12v relay board works well for Arduino/ ARM /PIC /AVR /MCU/Raspberry/CNC machine/ PS4 etc.
