Safety Instrumented Systems

TinoVC DMCC - TÜV Rheinland

The main objective is to provide all engineers involved in safety instrumented systems with elementary and necessary knowledge about functional safety, based on the leading international functional safety standards IEC 61508 and IEC 61511.

A second objective is to give attendants the possibility to obtain the worldwide acknowledged FS Engineer (TÜV Rheinland) certificate upon successful participation in the exam.

IEC 61508 ed2.0, released in April 2010, clearly indicates as a ‘Normative’ requirement, that anybody involved in safety lifecycle activities shall be competent to carry out the activities for which they are accountable.

Take advantage of this course, examination and certificate to prove your clients, peers and management, your competency in the field of Functional Safety. Success in the final examination confirms your functional safety knowledge on your personal name, adding a great value to your professional career and image.

Target Group

Plant and quality managers; System integrators and independent consultants; Control and process engineers; Maintenance and instrumentation engineers; Managers of engineering departments; Risk, reliability, safety and quality engineers; Loss prevention engineers; Sales engineers; Sales managers; Marketing specialists for safety-products, systems and services; Technical staff involved in any part of SIS lifecycle that need or want to develop their competency in Functional Safety.
