Overspeed trip — for SIL 3 with certificate

FlexSILon TMC



At the initiative of the application engineers, protection functions have been integrated in FlexSILon TMC. The X-MIO 7/6 O1, for example, performs the overspeed trip function at SIL 3 level.


  • Non-reactive and independent of the HIMax CPU

  • Reaction time of well under 20 milliseconds

  •  Parameter setting using the SILworX engineering tool

X-MIO is simply mounted on the HIMax backplane — also redundantly, on request. This certified function from the prevailing practice is a further unique attribute of HIMA. Applications can be implemented according to API 670.
