TÜV certification achieved by AUMA confirms that the company’s SQ .2 part-turn actuators, SA .2 multi-turn actuators and AC .2 actuator controls in SIL version comply with the highest safety requirements. The actuators have achieved full latest IEC 61508 edition 2 certification and are approved for safety-related systems up to SIL 3 (for redundant system architecture). The TÜV certification also applies to low temperature versions for temperatures ranging from -60° C to +60° C.
The safety function of AUMA’s SIL actuators can be configured with different seating criteria, including forced limit or torque seating to protect the mechanical integrity of the valve. If required by the application, different seating criteria for the safety function and standard actuator functionality can be set. The investment in standards accreditation by the leader in modular electric actuation technology supports increasing demand for functional safety/SIL, particularly for installations with high risk potential for both people and the environment. The initiative underpins AUMA’s commitment to comply with the industry’s highest safety standards.
In addition to the company’s top-of-the-range SIL devices designed to meet the highest safety requirements, AUMA offers a Safety Figure Calculated (SFC) range of actuators that is extremely adaptable with a high degree of configuration capability and cost flexibility. These actuators, with safety parameters assessed by exida – a leading functional safety notifying body, are ideally suited for applications with modest SIL1 or SIL 2 safety requirements. The SFC product range comprises SA and SQ actuators with AM and AC (standard version) actuator controls plus GK, GST and GS gear boxes.
