Florence, KY – Balluff’s IO-Link™ system enables quick and easy expansion or simplification of Profibus and Profinet networks. Users and OEM equipment builders can now achieve a higher level of flexibility and easier system modification for their networks at significantly lower costs.

A Balluff IO-Link Expansion module attaches directly to the Profibus or Profinet network, either as a new node or by substituting for an existing node. Then, using standard low-cost three-conductor M12 cordsets, users attach up to four intelligent IO-Link sensors up to 20 meters away from the IO-Link expansion module. Hardware includes network expansion modules, sensor hubs, standard M12 non-shielded three-conductor cordsets, standard sensors, and intelligent IO-Link sensors which are available in a range of different sensing technologies, including distance feedback, RFID, and pressure monitors, among others. This provides less expensive Profibus/Profinet solutions in automation applications for building and retrofitting machines with an overall cost savings in components, cabling, installation and integration effort.

For instance, one Balluff Profibus IO-Link expander and four discrete sensor hubs can replace five discrete Profibus modules, with 30-40% savings including network components, network cabling, and integration time, while providing 78 inputs. One expansion module and a combination of IO-Link sensors and/or sensor hubs can replace up to five nodes, reducing expensive network cabling and time-consuming controller configuration without the need for node addresses or expensive Profibus chips or software.

The heart of the Balluff system is the sensor hubs which allow connection of 16 standard discrete sensors to the network per hub. Up to four hubs per expansion module can be put on each node, giving a total of 76 sensors per Profibus node.
