Functional Safety

We are the leading provider of development services in the area functional safety covering measurement, drive, and control technology, medical engineering, for the associated control devices and for components of collaborative robot systems. embeX was the first company worldwide to be awarded the highest maturity level for Functional Safety Management (FSM) according to IEC 61508 by TÜV Rheinland.

embeX develops embedded systems ranging from SIL 1 to SIL 4, from PL a to PL e, from medical device class I to III. We advise and support our customers in all issues relating to functional safety, when implementing a functional safety management system and during assessment and certification.

Our safety experts actively work in the safety standardisation groups such as IEC 61508 (SIL) and maintain constant contact with all renowned notified bodies.
