DC 12V 4-Channel 4-CH Relay Module with Optocoupler H/L Level Triger for Arduino

Product information

Module 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 12V;
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)
