We ‘d like to see something help us to have a nice home automation application, or develop some smart home products, this 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.
Features
- More safe with relays PCB pin anti-climb design.
- With ESP8266 Wifi module,4-layers board design.
- One output status indicator, one input status indicator.
- 220V 10A relay, one normally open, one normally closed.
- One way optocoupler isolation input, TVS input protection.
- Access control server via TCP CLIENT mode Via HTTP protocol control.High-current terminals.
- Input overvoltage protection, input with TVS, when voltage exceeds 33V, automatic protection will operate.

Jargon buster
Plain-language definitions for the technical terms used above.
- DC
- DC means direct current, where electricity flows in one constant direction, as supplied by batteries, USB ports and many plug-pack power supplies. When a product specifies DC, it runs from a DC supply rather than mains AC, so you need to provide the correct voltage and polarity.
- over-voltage protection
- Over-voltage protection is a safety feature that shuts down or limits the circuit if the input or output voltage becomes too high. It matters because excessive voltage can damage both the power supply and the device being tested.
- PCB
- A printed circuit board (PCB) is a board, usually rigid, with etched copper tracks that connect electronic components together without loose wiring. Components are mounted on the board and signals route between them through the copper layout.
