Abstract

Electro-optical shaft encoders with a Profibus-Interface have been proved of value for many years. For the application in safety-relevant areas, a variant has been developed fulfilling the requirements of IEC 61508 and meanwhile certified according to SIL2. The paper describes the configuration of shaft encoders and their specific design according to this standard.
