TRAC is a software tool from ABB Engineering Services, for assessing your Safety Instrumented Systems (sometimes known as process trips or interlocks) against the requirements of IEC61511 (Functional Safety - Safety Instrumented Systems for the Process Industry). It provides the user with a tool to efficiently record the assessments of Safety Instrumented Systems, storing the details of the assessments in a central location (accessible by any client on the same network) and providing an audit trail.

TRAC is a proven approach for the assessment of Safety Integrity Levels (SILs) and architectural technical specifications of Safety instrumented Systems, meeting the requirements of IEC61511. It is used by hundreds of users around the world in both small and multinational companies.

• Hazard Assessment using Risk Graph and or LOPA
• Identification of the Target SIL
• Development of the Design SIL of an appropriate Safety Instrumented Function SIF
• Utilisation of component Reliability Data
• Inclusion of voting, common mode and duty factors
• Graphical display for optimising proof testing for both inputs and outputs of the SIF
• Optimised cost
• Allows efficient re-assessment and verification of original assumptions based on Achieved SIL feedback
• Full reporting suite as part of your SIS Safety Case management requirements
