AUMA offers sophisticated control for premium safety requirements with AC 01.2-SIL or ACExC 01.2-SIL actuators controls. SA .2 and SQ .2 actuators combined with these actuator controls can be deployed in safety-related system systems up to SIL 3. AC 01.2 actuator controls in SIL version are equipped with an additional SIL module designed for the execution of safety functions. In case of an emergency at the plant and when requesting a safety function, the standard logic of AC is bypassed and the safety function is performed via the safe SIL module. Consequently, the safety function always overrules standard operation. SA .2 and SQ .2 actuators equipped with these actuator controls have been certified by TÜV Nord. They are suitable for the following safety functions:
