ESP8266 10A 220V Network Relay WIFI Module will take charge of your electrical equipment by WIFI control.
In addition to the remote control of this relay has the advantage, it also has a wide input voltage range(DC7V-DC30V), and input over-voltage protection, input with TVS, as long as the input voltage exceeds 33v, it will automatically protect. Similarly, the input current exceeds a certain value will turn on automatic protection. The circuit board has an output status indicator and an input status indicator. It can be accessed through the TCP client server control can also be controlled through the HTTP protocol, the control of diverse and easy to operate.
