Modul ESP8266 ESP-01 4 Channel Relay Development Board

Detail Modul ESP8266 ESP-01 4 Channel Relay Development Board

ESP8266 WIFI 4-Channel Relay Module is 4 channel WIFI relay module carried a ESP8266 WIFI module and mature 8 bit MCU, with Professional switching power supply could control the relay by Android phone APP within the local area network (LAN).It is easy to set .

Fitur:
1>.Integrated design.
2>.APP remote control.
3>.DC 5V work power supply.
4>.On board high quality MCU and ESP8266 WIFI module.

5>.Support Two Work Mode:
Mode 1:cellphone carry on WIFI module directly.
Mode 2: cellphone and WIFI module carry on router together.
Additional features: USB Relay Module (without ESP8266).

6>.Transmission distance:
In the open environment,when mobile phone is carrying on the WIFI module ,maximum transmission distance is 100 meter.
When the WIFI module and cell phone carrying on the router at the same time the signal transmission distance depends on router signal.
7>.Use the Smartconfig technology to complete the configuration of the account and password of the ESP8266 WIFI module on the mobile APP. The configured account and password will be memorized after power off.
8>.Optocoupler isolated output, safe and reliable.
9>.The board contains 220V,10A/250V AC 10A/30V DC Songle original relay, which can continuously absorb 100,000 times, with the protection of diode current and short response time.
10>.PCB material and manufacturing process meets the standards of RoHS.
11>.On board relay LED indicator , mode option and working statue LED indicator.
12>.Reserved UART debug interface and MCU download port for program.
