Features:
- Trusted TMR System Speed Monitor Module
- Triple Modular Redundant (TMR), fault tolerant (3-2-0) operation
- designed specifically for safety-critical speed monitoring in industrial systems that require high integrity and fault tolerance
The Trusted TMR processor is a fault-tolerant design based on a Triple Module Redundancy (TMR) architecture, operating in a synchronous configuration. Figure 1 illustrates the basic structure of the Trusted TMR processor module in a simplified manner.
The module comprises three Processor Fault Isolation Regions (FCRs). Each FCR contains an NXP PowerQUICC® II™ series processor and its associated memory (EPROM, DRAM, Flash ROM, and Flash RAM), memory-mapped I/O, a voter, and glue logic. Each processor FCR employs a 2/3 (2oo3) read permission voting mechanism to vote on the memory systems of the other two processor FCRs to eliminate operational discrepancies.
The T8442C ICS triplex Speed Monitor Module may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
The module's three processors are responsible for storing and executing the application, scanning and updating the I/O module, and detecting system faults, respectively. Each processor executes the application independently but runs synchronously with the other two processors. Each processor has an interface that includes an input voter and difference detection logic.
Steam Turbine Overspeed Protection: Its most important function is to protect steam turbines and gas turbines in power plants and refineries. It can detect if a steam turbine exceeds its safe speed limits and trigger an emergency shutdown (ESD) to prevent catastrophic mechanical failure.
Compressor and Pump Monitoring: Used in the oil and gas industry to monitor large centrifugal compressors and high-pressure pumps on offshore platforms and pipelines.
Rotating Equipment Management: Suitable for any heavy industry (such as chemical or steel mills) where rotating equipment must operate within strict speed parameter ranges to ensure safety and process stability.
