Features:
- Redundant I/O 16-Ch Digital Input 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 T9802 ICS triplex Redundant I/O 16-Ch Digital Input 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.
T9802 is widely used in the following high-risk industries:
Oil & Gas: Refinery, offshore platform, and pipeline monitoring.
Power Generation: Safety control for nuclear and thermal power plants.
Chemicals: Batch management and safety interlocks for reactive chemicals.
Manufacturing: Heavy industries such as steel smelting and automobile manufacturing.
