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<\/em> (Encoder(SR)<\/em>) in terms of their functional safety<\/em> considerations, electrical safety and environmental conditions. It applies to Encoder(SR)<\/em>, being sensors as part of a PDS(SR)<\/em>. This document can also be referred to and used for Encoder(SR)<\/em> in any other safety-related application, for example safety-related position monitoring. This document is applicable where functional safety<\/em> of an encoder<\/em> is claimed and the Encoder(SR)<\/em> is operating mainly in the high demand or continuous mode. The requirements of IEC 61800-5-2:2016 for PDS(SR)<\/em> apply to Encoder(SR)<\/em> as applicable. This document includes additional or different requirements for Encoder(SR)<\/em>. It sets out safety-related considerations of Encoder(SR)<\/em> in terms of the framework of IEC 61508 (all parts), and introduces requirements for Encoder(SR)<\/em> 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)<\/em> in relation to the safety performance of safety sub-function<\/em>(s) of an Encoder(SR)<\/em>.<\/p>\n
