5V 2 Channel Red Color Relay Module
1. Maximum load:AC 250V/10A, DC30V/10A
2. SMD optocoupler isolation, strong driving ability, stable performance; trigger current 5mA
3. the module voltage 5V
4. each channel module can be set high or low triggered by jumper
5. fault-tolerant design, even if the control line is broken, the relay will not operate
6. power indicator (green), 2 relay state indicator (red)
7. interface design user-friendly, all interfaces are available through the wiring terminal direct connection leads, very convenient
