This is the web edition of the original ⮫ AC500-S safety user manual, version 1.3.2. This web edition is provided for quick reference only. The original safety user manual must be used to meet functional safety application requirements. |
The AC500-S safety modules are safety-related up to SIL 3 according to IEC 61508, max. SIL 3 according to IEC 62061 and PL e according to ISO 13849-1, as certified by TÜV SÜD Rail GmbH (Germany).
The AC500-S is a safety PLC which operation reliability is significantly improved compared to a non-safety PLC using 1oo2 redundancy in the hardware and additional diagnostic functions in its hardware and software. The embedded safety integrity diagnostic functions are based on the safety standards current at the time of certification⮫ TÜV SÜD Rail Certification Report for AC500-S [1]. These safety integrity tests include test routines, which are run during the whole operating phase, making the AC500-S safety PLC suitable for the safety machinery and process applications up to SIL 3 according to IEC 61508, max. SIL 3 according to IEC 62061 and PL e according to ISO 13849-1.
NOTICE
Please refer to TÜV SÜD Rail Certification Report for AC500-S⮫ [1] for a complete list of standards and further details, like versions of standards, etc.
The proof test interval for the AC500-S safety PLC is set to 20 years.
PFH, PFD, MTTFd, category and DC values from IEC 61508, IEC 62061 and ISO 13849-1 for AC500-S safety modules satisfy SIL 3, max. SIL 3 and PL e requirements⮫ “Safety values”.
