FUNCTIONAL DESCRIPTION:
The 5432-275 is a high-precision Power Sense I/O Module specifically designed and manufactured for the Woodward MicroNet control system. It acts as the critical interface for monitoring the electrical parameters of a generator and its associated utility bus. By providing real-time data on voltage, current, and frequency, it enables the MicroNet CPU to perform complex functions such as automatic synchronization, load sharing, and generator protection.
ADVANCED ELECTRICAL SENSING
The Power Sense I/O Module is equipped with two sets of 3-phase voltage inputs, one for the generator and one for the bus, along with a set of 3-phase current inputs. This allows the module to calculate essential power data, including real power (kW), reactive power (kVAR), and power factor. The 16-bit processing architecture ensures that these calculations are high-resolution, providing the stability required for precise governing of turbine-driven generators.
SYNCHRONIZATION AND LOAD SHARING
A primary role of the Power Sense I/O Module is to facilitate the safe paralleling of a generator to a live bus. It continuously monitors the phase angle, frequency, and voltage differences between the two sources. This data is fed to the MicroNet synchronization algorithms to adjust the turbine speed and excitation until the "in-phase" condition is met. Once paralleled, the module continues to monitor kW and kVAR to ensure the generator carries its proportional share of the system load.
SYSTEM PROTECTION AND DIAGNOSTICS
The Power Sense module provides a layer of electrical protection. It can detect conditions such as reverse power, overcurrent, and phase imbalance. Integrated diagnostics monitor the health of the internal PT (Potential Transformer) and CT (Current Transformer) sensing circuits. If a loss of signal is detected, the module immediately alerts the central controller, allowing for a safe transition to a backup mode or a controlled system shutdown.

What is the Woodward 5432-275?
The 5432-275 is a Power Sense module for MicroNet systems, used to measure 3-phase voltage and current from a generator and its bus for synchronization and load control.
Can this module handle 480V directly?
No. The inputs are designed for secondary levels (0–150 Vac and 0–5 A). Standard external Potential Transformers (PTs) and Current Transformers (CTs) must be used to step down the high generator voltages to the module's input range.
Does this module support both 50Hz and 60Hz systems?
Yes. The Power Sense I/O Module is designed to operate within a frequency range of 40 to 70 Hz, making it suitable for both international 50Hz and North American 60Hz power standards.
Is the 5432-275 compatible with MicroNet Plus?
Yes, it is fully compatible with both the standard MicroNet and the MicroNet Plus VME-based chassis. Ensure your system's GAP (Graphical Application Programmer) software is updated to support the specific module revision.
