IO-Link: IoT-Interface of the Sensors


What is IO-Link?

IO-Link is the first globally standardized IO technology (IEC 61131-9) for communicating with sensors and actuators. The powerful point-to-point communication is based on the well-known 3-wire sensor and actuator connection without any additional requirements for the connection technology.

IO-Link is THE intelligent interface for machine and process optimization in the sense of Industry 4.0. The system architecture can look as follows:

What can you expect from IO-Link?

• Interference-free digital communication at sensor level
• Inexpensive installation due to unshielded 4-pole cables
