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.
