Protective devices Safety inspections designated EN ISO 13849-1 and EN 62061 respectively. EN 62061 is applicable only to electrical control systems. Both replace the old standard EN 954-1, which will become obsolete on December 31, 2011, after a 3+2-year allowable transition period. Furthermore, both fall under the basic safety of machinery Structure Category to EN ISO 13849-1 and Typical representation in the - 10 - particular features safety-related block diagram Two-channel, with fault detec-tion .
