ES30F27 ESP32 Industrial DIN Rail Expansion Board – 8DI 8DO 10A Relay 7ADC RS485 I2C SPI GPIO for PLC IoT Automation

ES30F27 is an ESP32 expansion board designed and produced by eletechsup. It has a DIN rail enclosure and rich onboard resources. In addition to 8 NPN opto-isolated inputs and 8 10A relays, it also leads to I2C SPI interfaces. Each functional port is clearly marked to facilitate the development of IOT projects.

Note: This board cannot work independently, must be under the control of the 30PIN ESP32 board to work,If you do not have a ESP32 board, purchase it separately

4 Size 175*90*40mm



5 Weight : 240g



Note: ES30F27 is an expansion board and cannot work alone. You need to prepare your own ESP32 board and program it.



As long as you write ESP32 code,You can use it to achieve a variety of delay timer function,such as:



WIFI remote control switch



PLC digital analog IO expansion board



I2C SPI input and output controller



RS485 Master-Slave Device(PLC MCU),



Motor forward and reverse,



Timing on,Timing off,



Power-up delay,Trigger delay,



Infinite loop delay,



A finite number of cyclic delays,



Power sequencer,



And so on.



This is an expansion board based on 30PIN ESP32 Board. We only provide some Arduiuo codes for testing the hardware. More codes and functions need to be developed by yourself.

ESP32 can be developed using ESPhome, and can develop the following but not limited to WIFI HTTP MQTT Modbus and other protocols (we do not provide these routines, you can find relevant learning materials on the ESP32 official website)
If you need more functionality, write your own code. We do not provide additional code and technical support



NOTE : Please use this specification ESP32 board:
1 30PIN IO;2 Pin width 25.4MM (board width about 28MM)




Note: ES30F27 can not work independently, must be under the control of the 30PIN ESP32 board to work,If you do not have a ESP32 board, purchase it separately
