Features 1、Adopts double-panel design PCB, single-chip microcomputer as control, stable and reliable performance, strong anti-interference, no false trigger, performance is far superior than CD4013 2、The high‑power Zener tube provides sufficient and stable voltage, and has enough heat dissipation holes to ensure stable and reliable operation of the product for a long time. Other sensor modules can be used for triggering, as long as it is a low‑level trigger 3、Has a protection diode for preventing the power supply from being connected reversely. The product will not be damaged if the power supply is reversed for a short time, and the relay is used to control the load. The load can withstand 10A (AC) and 30V 10A (DC) 4、With a touch switch as a product test, it can directly check the stability of the product. The product is equipped with a terminal block and lead, the relay is closed and locked, press it again, the relay is disconnected, or an external trigger switch 5、Household appliances control, various household lamps control, factory equipment control, used for the control of various small current control high-voltage high-power products Specification Item Type: Relay Module Power Supply Current: More Than 100mA Life: 1 000 000 Times Package List 1 x Relay Module
