IEC 61800-5-3:2021, which is a product standard, specifies requirements and makes recommendations for the design and development, integration and validation of safety-related;encoder;(;Encoder(SR);) in terms of their;functional safety;considerations, electrical safety and environmental conditions. It applies to;Encoder(SR);, being sensors as part of a;PDS(SR);. This document can also be referred to and used for;Encoder(SR);in any other safety-related application, for example safety-related position monitoring. This document is applicable where;functional safety;of an;encoder;is claimed and the;Encoder(SR);is operating mainly in the high demand or continuous mode. The requirements of IEC 61800-5-2:2016 for;PDS(SR);apply to;Encoder(SR);as applicable. This document includes additional or different requirements for;Encoder(SR);. It sets out safety-related considerations of;Encoder(SR);in terms of the framework of IEC 61508 (all parts), and introduces requirements for;Encoder(SR);as subsystems of a safety-related system. It is intended to facilitate the realisation of the electrical/electronic/programmable electronic (E/E/PE) and mechanical parts of an;Encoder(SR);in relation to the safety performance of;safety sub-function;(s) of an;Encoder(SR);.
