1-Channel 5V High Level Dual Power Relay Module - Red + Blue
1. Use of the original SMI type of double relay; 2. Input is two way to trigger£¬ but there are four output; 3. Output of the relay has two public side£¬ often beginning£¬ often closed£¬ and two independent work; 4. Use of high temperature resistance PA terminal£¬ the quality is very good; 5. With a working state indicator relay; 6. With the SS8550 original transistor to do the switch tube£¬ the big current is more quality assurance; 7. High level of the module is triggered£¬ that is£¬ with DC positive trigger.
