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 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 the relay to disconnect. Fool-type wifi control module, no need to , 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 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- and 4- supports), you can remote control AC/DC motors.
