What is IO-Link?

IO-Link communication covers the "last meters" to the industrial end device, e.g. a sensor or an actuator, as a point-to-point connection. The connection of the end devices is carried out via an intermediary IO-Link-Master and at least a 3-core cable with standardised connectors.



The majority of end devices can be powered directly via the mains power of 24V.



Who needs IO-Link?

  • Manufacturers of sensors and actuators
  • Manufacturers of interfaces between field bus systems and field devices
  • Complete solution providers in control technology

What advantages does IO-Link offer?

IO-Link sensors and actors are connectable to different fieldbus systems, if a appropriate IO-Link master gateway is available. Cost effective microcontrollers allow to integrate more sophisticated functionality into even simple devices. IO-Link offeres a standardized mean to access these functions.

Standardization according to ISO 61113-9 guarantees extensive compatibility between devices from different manufacturers. The advantages of IO-Link are based on three points:

  • Simplification of installation
  • Simplification of configuration and parameterisation
  • Additional diagnosis capabilities
