Our Trusted® fault tolerant control system is designed to meet a wide range of safety requirements. This safety instrumented solution features a triple modular redundant (TMR) system that identifies the source of a fault. The system reacts immediately to contain system faults, helping to achieve your safety integrity requirements.
Maximizes Safety and System Availability
Trusted Incorporates a Fault Tolerant Architecture to Minimize System Trips
The Trusted TMR design uses a majority voting process to identify the source of a fault. Random hardware failures will cause one of three control ‘slices’ to react differently to the others. The voting system captures and reports the discrepancies. The Trusted TMR system will react immediately to contain system faults, helping to confirm it meets your safety integrity requirements.
