Functional safety in mobile machines

Functional safety in mobile machines

More and more safety-critical functions are being incorporated today in mechanical engineering, automation, electrical engineering and process technology. Programmable systems are being used increasingly in this field.

Functional safety is the portion of total system safety which depends on the correct function of safety-critical systems for minimizing risk. This includes electrical, electronic and programmable electronic systems (E/E/PES).

These systems must carry out their intended functions (safety functions) within defined error conditions and with defined high probability. The aim is to achieve and maintain a safe system condition.

The technical requirements with regard to functional safety are derived from the standards IEC 61508 and EN 13849. For this, HYDAC provides controllers and software certified to IEC 61508, SIL 2 / 3 and EN 13849, PL d.

HYDAC offers sensors for pressure,;position, and distance for applications with increased functional safety, and can provide support and advice to the customer, as required,through the entire product development cycle – from design and simulation,right through to the application software, commissioning and series production.
