      Overview Manuals Principle Primary Applications

      Features:

      • Trusted TMR System 24 Vdc Digital Input Module - 40 Channel
      • Triple Modular Redundant (TMR), fault tolerant (3-2-0) operation
      • It is designed for high-reliability, safety-critical industrial applications requiring SIL 3 certification
      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 T8403 ICS triplex Digital Input Module may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).
      ICS Triplex T8403 Digital Input Module maunal(Datasheets), Link 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.
      This module is widely used in emergency shutdown (ESD) and fire and gas (F&G) systems in high-risk industries:
      Oil & Gas: Monitoring refinery operations, offshore platforms, and pipelines to enhance safety.
      Power Generation: Used for turbine control systems and power distribution monitoring.
      Chemicals: Monitoring constant flow control and reactor safety interlocks.
      Manufacturing: Automating assembly lines and managing intelligent fire-fighting water supply systems.
