WOODWARD 5466-253 Analog Combo TMR – Triple Modular Redundancy Analog I/O Module
Imagine a gas turbine running at full load when its analog input module silently fails — no alarm, no graceful shutdown, just a cascade of erroneous signals feeding the control loop. Within seconds, the governor loses its reference, fuel metering goes unchecked, and the entire unit trips offline. In critical power generation and industrial turbine applications, a single point of failure in the analog signal chain is not a theoretical risk — it is a documented cause of unplanned outages costing hundreds of thousands of dollars per hour. The WOODWARD 5466-253 Analog Combo TMR module exists precisely to eliminate that vulnerability, delivering fault-tolerant analog I/O with Triple Modular Redundancy architecture that keeps your control system running even when individual channels degrade.
The 5466-253 occupies a pivotal position within Woodward’s TMR (Triple Modular Redundancy) control platform — a system architecture trusted by turbine OEMs, power utilities, and EPC contractors across six continents. Unlike simplex or dual-redundant analog modules, the TMR design employs three independent signal paths with majority-vote logic, meaning the system continues to output a correct, validated analog value even if one of the three channels develops a fault. This module is specifically engineered for the most demanding continuous-process environments: gas turbines, steam turbines, compressor trains, and large-scale power generation assets where availability targets exceed 99.99%.

Key Features & Benefits
- Triple Modular Redundancy: Three independent analog signal paths with majority-vote arbitration — a single channel fault does not interrupt control output.
- Combo I/O Design: Integrates both analog input and analog output functions in a single module, reducing chassis slot consumption and simplifying wiring.
- Continuous Self-Diagnostics: On-board diagnostics continuously compare the three signal paths, flagging discrepancies before they escalate to system faults.
- Hot-Swap Capable: Designed for replacement under power in compatible TMR chassis configurations, minimizing maintenance downtime.
- High Signal Integrity: Precision analog conditioning ensures accurate representation of process variables — critical for governor control and protective relay interfaces.
- Proven Platform Reliability: Part of Woodward’s field-proven TMR architecture deployed in thousands of turbine control applications worldwide.
Industry & Equipment Applications
- Gas Turbine Control: Fuel metering valve position feedback, inlet guide vane control, exhaust temperature monitoring.
- Steam Turbine Governing: Speed/load analog reference signals, extraction pressure control loops.
- Compressor Train Automation: Anti-surge control analog I/O, suction/discharge pressure signal processing.
- Power Generation & Utilities: Combined-cycle plant DCS integration, generator excitation analog interfaces.
- Oil & Gas Processing: Offshore platform turbine drivers, LNG compressor control systems.
- Marine Propulsion: Ship propulsion turbine control systems requiring SIL-rated redundancy.
