Industrial I/O Module with 2G Connectivity

Client Background


The client is a leading player into Industrial Automation Systems with interests in industries such as Paper, Cement, Oil & Gas and Power.

Project Information:


The project was to build a small I/O module with 2G Connectivity for remote monitoring and control. 2G connectivity was important as some of the I/O modules were in remote areas and the system needed monitoring. The specs were:

  • Digital and Analog Inputs
  • RS485 Interface
  • 2G Connectivity



Teq Diligent worked with client team to freeze the system specs.  The system designed based on the specs was:

  • STM32F4 Based hardware
  • 4x Isolated Digital inputs
  • 2x Single-ended Analog Inputs (5-20mA Current/0-5V Voltage)
  • 4x Relay outputs
  • 2G Module for remote connectivity
  • Firmware development
  • Application for remote data monitoring



Using this small remote I/O module, client was able to achieve improved system efficiency. The remote data monitoring helped client know the system status and predict as well as resolve issues in a much better way.
