ICS Triplex T8442 Product Brief Description

The ICS Triplex T8442 is a Trusted TMR speed monitor module for the T8000 safety instrumented system. It adopts triple modular redundant architecture to monitor shaft speed and acceleration of rotating equipment, executing overspeed and over-acceleration safety trip protection. As an independent fault-tolerant protection subsystem, it achieves SIL3 safety integrity for critical rotating machinery protection.

Product Features

• TMR triple modular redundant design, compliant with SIL3 safety level
• Supports up to 3 groups of rotating machinery speed monitoring and protection
• Real-time speed and acceleration measurement with overspeed trip function
• Works with T8846 speed input FTA for magnetic and active speed sensors
• Independent fault-tolerant control, still operates when main processor fails
• Comprehensive self-diagnostics and hot-swap support for online maintenance

Application Scenarios

• Steam turbine and gas turbine overspeed protection systems
• Compressor, generator and large pump machinery safety protection
• Power plant rotating equipment safety instrumented systems
• Petrochemical and refinery critical rotating machine interlock
• Offshore platform high-speed rotating equipment safety monitoring
