EN ISO 13849-1:2006 introduces the performance levels from PL a (lowest) to PL e (highest) and is determined by: • EN ISO 13849 categories (Cat B, Cat 1,….Cat 4) • Diagnostic Coverage (DC) • Mean Time To Dangerous Failure (MTTF d) The first two parameters relate to the control system, meanwhile MTTF d stands for the quality and David Collier of Pilz Automation Technology explains the changes that were introduced in the third edition of BS EN ISO 13849-1, published in December 2015, which is identical to international standard ISO 13849-1:2015 and European harmonised standard EN ISO 13849-1:2015. The HR2S series safety relays provide users increased functionality and flexibility when designing system to meet safety requirements. HR2S safety relays are compact modules designed to allow machine operation only when all safety controls such as Interlock Switches, E-stop switches, Light Curtains, etc. are functioning properly and aren’t reporting hazardous conditions. In October 2006 EN ISO 13849-1 was officially adopted as the successor standard to EN 954-1.

MTTFd (Mean time to dangerous failure) is an expectation of the mean time to dangerous failure on the whole or part of a safety-related system. The MTTFd is

Series MX SAFEMAX valves comply with ISO 13849-1, which refers to the safe design of control systems that perform safety functions. These valves are equipped with an integrated sensor that detects the position of the spool and checks whether the system is rapidly discharged in case of emergency. The single channel valve is a component classified
