Woodward 5437-1124 MicroNet TMR I/O Module

Product Brief Description

The Woodward 5437-1124 is a rack-mounted MicroNet TMR triple modular redundant I/O module, designed for Woodward MicroNet turbine control and protection systems. It acquires field analog and digital signals, performs signal conditioning and voted data processing within TMR architecture. Built for high-reliability power generation applications, this module provides fault-tolerant input/output handling for gas turbines, steam turbines and generator control, with comprehensive onboard diagnostics and gold-plated backplane connectors for long-term stable operation in power plant control cabinets.

Product Functions

• Collect digital and analog field signals including speed, pressure, temperature, valve position and contact status
• Execute triple modular signal voting to mask single hardware faults and avoid unplanned turbine trips
• Signal filtering, isolation and conversion of raw field measurements for the MicroNet main controller
• Output control and trip commands to actuators and protection circuits based on control logic results
• Continuous self-diagnosis for channel faults, wiring breaks, short circuits and internal hardware anomalies
• Communicate with the main processor via backplane bus and support fault alarm and event recording for maintenance

Application Scenarios

• Combined cycle power plant gas turbine and steam turbine MicroNet TMR control systems
• Thermal power station generator control, governor and safety protection cabinets
• Oil & gas turbine-driven compressor and pump control & safety interlock systems
• Captive power plant and industrial cogeneration turbine control racks
• Offshore platform and marine turbo machinery fault-tolerant control applications
