The highest functional safety level is ensured by the combinations of AC .2 SIL with multi-turn actuators of the SA .2 range or part-turn actuators of the SQ .2 range, certified by TÜV according to IEC 61508 (ed.2). These combinations can be used up to SIL 2 and in redundant version (e.g. 1oo2) even up to SIL 3. They comply with the latest and most demanding issue of IEC 61508 and offer superior flexibility when adapting the safety function within the respective safety instrumented system (SIS).
