ITEM NAME:1 way relay module 1-Channel 5V low level trigger relay expansion board JR Description: 1. Power supply to meet the scope , DC 5V-12V 2. The power required by the by -line diagram , is not reversed , although the protection circuit , but not for a long time reversed ; 3. Product regulator slight fever is a normal phenomenon , long working hours have a normal relay heat phenomena are normal ; 4. Relay load power to give leave some margin should avoid high-power ( about 2000W) and long working environment , there will be some impact on the life of the product . Features : 1. Double panel design PCB; 2. Chips made using stable and reliable control , stable and reliable performance , strong anti-interference , not false triggering , performance is superior than the CD4013 ; 3. Regulator has the power to provide adequate and stable voltage , and have enough vents to ensure stable and reliable product for a long time to work ; 4. With anti- reverse protection diode power , reverse power for a short time without any damage to the product ; 5. Use SONGLE genuine relay control load in 250V 10A ( AC ) and 30V 10A ( DC ) under load can withstand ; 6. Has a touch switch as product testing , stability testing of products directly ; 7. Can also trigger an external trigger switch , the products have a connection with a good seat and lead , more convenient to use ; 8. Triggering sensor module can also be used to do other triggers , are valid as long as the trigger is low , there are more functional expansion; Usage: Press the trigger button , the relay is locked , press again , the relay off , you can also add the trigger switch , and the use of low-level trigger . Control appliances , home of various lighting control, factory equipment control , current control for a variety of small high-voltage power control products . Packing list: 1*1 Channel Self-locking Relay Module 5V 1* Trigger Line.Press the trigger button, the relay is locked, press again, the relay off, you can also add the trigger switch, and the use of low-level trigger. Can also trigger an external trigger switch, the products have a connection with a good seat and lead, more convenient to use ;.
