The main function of this module: Default jog function: the phone is pressed to open, the relay is closed quickly (the default interval is 1S), and it is disconnected, and it also has the function of timing sharing. Press the inching self-locking selection button and the status light is on, at this time it is self-locking, the mobile phone presses to open the relay to pull in, and press to close the relay to disconnect.Fool-type wifi control module, no need to program, only need to download an APP, link WIFI to control the built-in cloud. As long as the module is connected to WIFI, the mobile phone can be controlled anywhere in the country.It has a signal indicator light and a relay pull-in indicator light. The board power consumption is less than 1W and the quiescent current is 80MA. The rated switching current is within 10A, and the switching voltage is within 250V.This product is a wireless switch supports momentary(inching) /self-locking/interlock work modes. Users can add the device to the APP eWeLink in order to remotely control connected home appliances or power circuits.Tap the work mode setting button manually, the product can change the working mode. When in inching mode, you can have two wiring ways to select: -Turn on 1s and then auto-off -Turn off 1s and then auto-on. When in self-locking mode, you can remotely turn on/off connected devices immediately. When in interlock mode(only 2-gang and 4-gang supports), you can remote control AC/DC motors.Main chip: WIFI moduleWorking voltage: DC 5V/7-3210A relayThe relay life is more than 1,000,000 times.Electrical insulation resistance 100MElectric shock withstand voltage 1000VThe maximum pull-in time of the relay is 15mS millisecondsThe maximum release time of the relay is 5mS millisecondsWorking temperature -40 degrees to +70 degreesWorking humidity 40% ~ 80%RHNote:The relays are switches without output, the power supply input (AC/DC) just for the PCBA.The product enables remote control of home appliances through the mobile application eWeLink, available on both Android and iOS.Supported functions include:Remote turn on/off *Timing SchedulesDevice SharingGroup ManagementCompatible with Amazon , Dot, Amazon TapWorks with Google Home, Google NestWorks with IFTTTThis product is compatible with Amazon .Style: CColour: GreenMaterial: PC+MetalPackage Contents:1 * Switch Relay Module (5V WIFI RF433)Only the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
