Product Description: WiFi ESP8266 2-Channel Relay Module for ESP-01S

A compact 2-channel relay module designed specifically for ESP8266, and more precisely for ESP-01 and ESP-01S boards. It is an extended version of the standard 1-channel controller, offering the ability to control two independent circuits. The module is equipped with a dedicated mounting socket, which makes integration easier without the need for an additional microcontroller on the board. It has additional S1 and S2 inputs and GPIO and UART pins, allowing connection of external sensors or buttons.

This device is a ready hardware base for automation systems. Please note that the communication module plugged into the socket is not included in the set.

Key Technical Features

• Number of channels: 2 independent relays
• Control microcontroller: dedicated socket for ESP8266 (ESP-01 and ESP-01S boards)
• Maximum relay load: 10A at 250V AC or 10A at 30V DC
• Logic supply voltage: 5V DC
• Relay section power supply: dedicated screw terminal
• Output configuration: NC and COM (normally closed circuit only, the module does not have NO contacts)
• Available expansion connectors: S1, S2, RX, TX, RX1, TX1, CLK, DAT, RST
• Physical dimensions: 55 x 45 mm

Example Applications

• Automation of lighting systems in buildings and outdoors
