Electric Automation Simplified.sio

The SiO Controller is a simple input/output control system that makes electric automation accessible and easy for everyone.


Look at the ON/OFF status of an input device to send ON/OFF commands to an output device.


Use SiO Controller to set up the conditions of an output. When the status matches these conditions, the controller sends a command to the output device.

Here are a few examples of what SiO Controller can do:

  • Sound a buzzer when a button is pressed, for as long as it is pressed.
  • Activate a lamp when a pre-determined number of pieces have passed a sensor.
  • Silence a buzzer when a limit switch detects a workpiece.

SiO Controller is ideal for making simple improvements to situations where a full PLC would be considered “over-engineering.

SiO is designed with first-time programmers in mind.

  • Simple, Multiple-Choice Programming
    Use “SiO Programmer,” our dedicated software for Windows OS, to set up the output conditions. The system is logically designed so that anyone can write programs after a little practice.
