Balluff IO-Link hub with integrated safety

Safety over IO-Link combines automation and safety in one system and represents efficient safety concepts from one source. Safety over IO-Link offers IO-Link advantages such as simple data transport and information exchange, high flexibility and universal applicability.

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 standard M12 cable. Even standard components such as binary sensors can be bundled via the safety I/O module. The module is connected to an IO-Link master, with safe communication with the control level provided by Profisafe/Profinet. Safety-relevant data is transferred through the master directly to the safety controller using the so-called tunnelling 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 standardisation results in savings over the entire life cycle of the machine. With Safety over IO-Link, applications can be adapted quickly and easily to changing requirements. Both equipment manufacturers and users thus benefit equally.
