For many machines, cranes, and vehicles, safety classification PL d (and even the lower level PL c) may be sufficient. Except for some transmitter/receiver combinations, Scanreco transmitters and receivers, are all PL d or PL e classified. The exceptions are combinations where the safety classification is not as important (a warehouse door perhaps, as opposed to manoeuvring a giant autonomous agriculture machine with a radio remote control).
What does PL x and SIL x mean?
There are two different safety classification systems governed by two different organizations:
- International Standard Organization (ISO) and
- International Electrotechnical Committee (IEC).
They follow the similar criteria but use different gradings. Easily explained:
PL – Performance Level (by ISO)
Ranges from PL a (lowest) to PL e (highest)
Covers safety related parts of machine control systems (electric, hydraulic, pneumatic and programmable) and lies under ISO 13849. It covers both function and design related issues.
SIL – Safety Integrity Level (by IEC)
Ranges from SIL 1 (lowest) to SIL 4 (highest)
Covers functional safety of electronic safety related systems and lies under IEC 61508. It does not specify exact design criteria but focuses on safety functions and the product’s life cycle.
