Features:
- 24V DC Power Supply module
- Triple Modular Redundant (TMR), fault tolerant (3-2-0) operation
- Hardware Implemented Fault Tolerant (HIFT) architecture
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 T8235 ICS triplex 24V DC Power Supply 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 three processors in this module are responsible for storing and executing applications, scanning and updating I/O modules, and detecting system faults. Each processor executes applications independently but operates synchronously with the other two processors. Each processor has an interface that includes an input voter, discrepancy detection logic.
Trusted TMR System Power Supply: As a 24V DC power module, it is designed for safety-sensitive environments with extremely high requirements for stability and precise power supply. It provides the necessary voltage for the core logic and communication of the trusted controller.
Slot Protection (Power Shield): The T8235 is commonly used as a power shield, covering unused slots in trusted power racks. This application is critical for:
Prevention of Contamination: Sealing empty slots to prevent dust, debris, or moisture from entering the power rack assembly.
System Integrity: Maintaining the physical protection and thermal characteristics of the 1U power rack.
Safety Instrumented Systems (SIS): Due to its robust design, it is used in critical safety functions, including:
Emergency Shutdown (ESD) systems.
Fire and Gas (F&G) detection loops.
Burner management systems (BMS) in petrochemical and power plants.
