Balluff is the first in the world to offer equipment manufacturers a simple-to-integrate, cost-saving safety solution based on IO-Link.

Safety over IO-Link combines automation and safety in one system and represents efficient safety concepts from one source.

Safety over IO-Link offers the proven IO-Link advantages such as simple data transport and information exchange, high flexibility and universal applicability.

A logical step in the direction of economical Industry 4.0 for users and for Balluff.

With integrated safety solutions and their own safety components, Balluff is now able to meet the demands of automation and safety equally.

Safety over IO-Link from Balluff is open to the sensor level: Balluff safety components as well as safety devices from other manufacturers can be connected to the Balluff-developed I/O module, the yellow safety hub, using inexpensive standard M12 cable.

Even standard components such as binary sensors can be bundled via the new safety I/O module. The module is connected to an IO-Link master, with safe communication with the control level provided by Profisafe/Profinet.

Simple and transparent system structure

Safety-relevant data are transferred through the master directly to the safety controller using the so-called tunneling procedure. Safety requirements up to PLe /SIL3 can be achieved.


Parameters are configured centrally using the programming interface of the controller. The simple and transparent system structure saves time and money in cabling, reduces the space requirement in the control cabinet, and enables leaner system concepts. The high degree of standardization results in savings over the entire life cycle of the machine.

Safety over IO-Link applications can be adapted quickly and easily to changing requirements. Both equipment manufacturers and users thus benefit equally.

Balluff is a leading manufacturer of a wide range of inductive, optical, vision, capacitive and magnetic sensors as well as linear position transducers, industrial RFID systems, connectivity and safety solutions.
