Product Description:

1. the module uses genuine quality relay, normally open interfaces Maximum load: AC 250V/10A, DC 30V/10A;

2. using SMD optocoupler isolation, driving ability, stable performance; trigger current 5mA;

3. the module Operating voltage 5V;

4. the module can be high or low by a jumper setting trigger;

5. fault-tolerant design, even if the control line is broken, the relay will not operate;

6. the power indicator (green), the relay status indicator (red)

7. the interface design of human nature, all interfaces are available through a direct connection terminal leads, very convenient
