2 Application and validity
2.1 Range of application
AUMA actuators and actuator controls in SIL version are intended for operation of industrial
valves and are suitable for use in safety instrumented systems in accordance with IEC 61508
/ IEC 61511.
2.2 Standards
Actuators and actuator controls meet the following requirements:
• IEC 61508 ED.2: Functional safety of electrical/electronic/programmable electronic
safety-related systems
2.3 Valid device types
The data on functional safety contained in this manual applies to the device types indicated
hereafter.
Table 2: Overview on suitable device types
Hardware, software and configuration of actuator and actuator controls must not be modified
without prior written consent by AUMA. Unauthorized modification may have a negative
impact on both safety figures and SIL capability of the products.
Information
In applications with requirements on functional safety, only AUMA actuator controls and
actuators in SFC or SIL version may be used.
AUMA actuator controls and actuators in SIL version can be identified by the letters “SIL” on
the nameplate.
