Features:
- Power Port 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 T8243 ICS triplex Power Port may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

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.
System Power Diagnostics: The T8243 is primarily used to monitor the input and output status of power supply racks. It reports critical faults such as out-of-range voltage, over-temperature, or fan failure to the main controller.
Redundant Power Management: In high-availability systems, it supports the management of dual redundant power feeders (Feeder A and Feeder B). It ensures that even if one power supply group or individual power supply fails, the system can seamlessly switch over or alert the operator while maintaining SIL 3 safety level.
Fault Reporting via Relays: This module integrates fault relays for AC feeder and DC output status. These relays provide hard-wired signals to external alarm systems or PLCs to indicate that power supply components require maintenance.
1U Rack Centralized Monitoring: It is mounted on the back of a 1U power supply rack that can accommodate up to three 750W power supply groups. The T8243 aggregates diagnostic data from all installed power supply groups into a single interface.
