R REIFENG 6pcs/lot 1 Channel 12V Relay Module Board Shield with Optocoupler Isolation Support High/Low Level Trigger

R REIFENG 6pcs/lot 1 Channel 12V Relay Module Board Shield with Optocoupler Isolation Support High/Low Level Trigger

• The module uses genuine quality relay, normally open interfaces , Maximum load: AC 250V/10A, DC 30V/10A.
• The module can be set high or low triggered by jumper
• Using SMD optocoupler isolation, strong driving capability, stable performance
• Fault-tolerant design, even if the control line is broken, the relay will not move.The interface design of human nature, all interfaces are available through a direct connection terminal leads, very convenient.
• If the relay module have any question,please contact the seller support.
