Sobre este producto
- NO(Normally open) maximum load: AC 250V/10A, DC 30V/10A. Equipped with power indicator light (green) and relay status indicator light (red).
- This 2-channel relay module uses DC12V relay and SMD opto-isolator, supporting high / low level trigger, widely apply to control various AC / DC appliances, and other devices with large current.
- Adopting patch optocoupler isolation, strong driving ability, and stable performance; Trigger current 5mA. The module can be triggered at high or low levels through jumper settings, also it can be controlled directly by 12V logic signals from microcontroller.
- Fault tolerant design, even if the control line is broken, the relay will not act.
- The wiring terminals are directly connected, making it convenient to use. There are 4 fixed bolt holes (with a diameter of 3.1mm) for easy installation.
