Overview

The Woodward 5501-372 Rev B is part of the MicroNet Digital Control System, specifically engineered for Triple Modular Redundant (TMR) configurations. This module provides high-density analog input and output channels, enabling precise signal acquisition and control in high-availability environments such as power generation, oil & gas, and marine automation.

Its triplex architecture ensures continuous operation even if one module fails, enhancing system reliability and uptime. Moreover, the 5501-372 supports voltage and current signal ranges, including 0–5 V and 4–20 mA, and integrates seamlessly with other MicroNet modules. In addition to analog processing, it includes diagnostic features and status indicators for real-time fault detection and maintenance.

Therefore, this module is ideal for turbine governors, compressor stations, and distributed control systems requiring robust analog I/O performance and redundancy.

Technical Data

Typical Applications

• Steam and Gas Turbine Control: Acquires analog signals for fuel, steam, and temperature regulation.

• Compressor Stations: Interfaces with pressure and flow sensors for real-time control.

• Power Generation Systems: Supports analog monitoring and actuation in generator protection and load control.

• Marine Automation: Manages propulsion and auxiliary systems with redundant analog feedback.

• Process Control: Enables high-resolution analog data acquisition in chemical, refining, and water treatment plants.

For instance, in a turbine control cabinet, the 5501-372 can monitor steam pressure and shaft speed while providing analog output to valve actuators. In addition, its triplex design ensures uninterrupted operation even during module failure.
