Feature:1. The relay module is a doublesided PCB design, made of resin material, hard and durable.2. Using singlechip microcomputer as control, stable and reliable performance, strong antiinterference ability.3. The highpower regulator provides sufficient and stable voltage, and has heat dissipation openings to ensure longterm stable and reliable operation of the product.4. Using antipower reverse protection diodes, shortterm reverse power supply, safer circuit control.5. Equipped with a junction box and leads, which can be connected to an external trigger switch.Specification:Item Type: Relay ModuleMaterial: ResinPower Supply Voltage: DC12VLoad: 250V 10A (AC) or 30V 10A (DC)Life: 1 million timesBoard Size: Approx. 50 x 25mm / 2 x 1inProduct Usage: 1. Press the trigger button, the relay is closed and locked, press again, the relay is disconnected, you can also connect an external trigger switch, and trigger with a low level.2. Household appliances control, various household lamps control, factory equipment control, used for the control of various low-current control high-voltage high-power products..Package List:1 x Relay ModuleNote:The voltage of the DC input terminal must be consistent with the voltage of the relay, and should not exceed the voltage range of the relay, otherwise the module will be burned.
