At SIL4, we assist with the difficult, time consuming and costly tasks required to deliver safety critical products to the market. We have over 30 years of experience in designing and delivering demanding safety critical systems that acceptably manage risk and comply with more pervasive safety standards such as IEC61508, IEC60601, EN50126, MIL-STD-882D and DO-178B/254. Our Electrical Engineering consulting services include solutions for industrial and manufacturing computer embedded systems.

 

SIL4 can enable your Safety Critical Application in the following ways:

• Assess the safety implications of projects, and determine the measures necessary to meet safety needs. Including architectures review and recommendations, system and circuit design and implementation.
• Cover all phases of the life of a safety-critical system from its conception and specification, design and verification through to its certification, installation, service and decommissioning.
• PHA – Preliminary Hazard Analysis; SHA – System Hazard Analysis;
• SSHA / FMEA – Sub-system Hazard Analysis / Failure Modes and Effects Analysis and FTA – Fault Tree Analysis
• OSHA – Operation and Support Hazard Analysis
• FMEA – All types and levels: From System FMEA and Sub-system FMEA, to Design FMEA, Process FMEA and Software FMEA to assure completeness and level of safety requirements. And recommended architecture / design approaches to assess and bound the necessary level of safety assurance and arrive at the most effective, efficient and robust approach possible. We will assist you from concept through certification, if needed.
• FMECA – Failure Modes, Effects and Criticality Analysis
• FMEDA – Failure Modes, Effects and Diagnostics Analysis which combines standard FMEA techniques with extensions to identify real-time diagnostic techniques.
• Calculating required SIL-Levels
• SFF – Safe Failure Fraction the fraction of the overall failure rate of a device that results in either a safe failure or a detected unsafe failure.
• PFD –Probability of Failure on Demand which is the measure of safety integrity for the SIF. It is the probability that
  the safety instrumented function will fail in a manner which will render it incapable of performing its intended safety function.
• Intrinsic Safety Design – Design architecture, testing and compliance.
• Turnkey embedded HW and SW design to implement Safety Integrity Levels (SIL) from SIL0 to SIL4.
• Provide scalable, safety critical embedded computing and I/O platforms to accelerate your application/product development.
