IO-Link

Simpler and more reliable operation with IO-Link

With IO-Link there is no longer a need to install a separate cable in order to communicate with sensors, transducers and actuators. IO-Link transmits bi-directional status and configuration data over the device's existing 4-lead connection.
In a typical application devices are connected via an IO-Link Master, which in turn is connected to a PLC or industrial PC via a standard field bus, such as EtherCAT, ProfiBus, ProfiNet or Ethernet/IP.
IO-Link standard supports a device description for each device (IODD - IO Device Description), allowing it to be identified and also to get information on its properties when connected to the system.
This is ideal both when commissioning a new installation and when replacing a device with a spare part. As the devices can be configured, fewer variants must be kept in stock.

RS Components can deliver both the products and the expertise allowing you to get up and running quickly, and make use of the advantages of IO-Link. See a selection of IO-Link products below.
