With the upcoming fourth generation STW relies on a new processor platform, the Infineon Aurix, which is available in different variants. Therefore a new platform concept arises that will be seen not only in control units and I/O modules of the fourth generation, but also in intelligent sensors.

The ESX IO-Modules are available as standard versions and variants of which in future also safety certified according to SIL2 / PLd.
