- TMR 24/48 Vdc Digital Output Module
- The T8461 I/O Complex Equipment Definition includes eight I/O boards
- Trusted TMR 24V DC/48V DC Output Module - 40 Channel
The Trusted TMR processor is a fault-tolerant design based on a Triple Module Redundancy (TMR) architecture, operating in a synchronous configuration.
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 T8461 ICS triplex Digital Output 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.
- Safety-Critical Controls: Primarily used in Emergency Shutdown (ESD), Fire and Gas (F&G) systems, and Burner Management Systems (BMS) to provide reliable command execution.
- Field Device Management: Connects and controls up to 40 digital field devices, such as solenoid valves, motors, actuators, and relays.
- Process Safety and Interlocks: Widely used in safety interlocks and process control in high-risk industries: Petrochemical/Oil & Gas: Controls critical valves and monitors compressors.
- Power Generation: Manages generator status and drives substation equipment.
- Pharmaceutical/Biotechnology: Handles safety interlocks and critical equipment in automated batch processing.
- Water Treatment: Controls emergency shutdowns of large water pumps and disinfection systems.
