Overview

The Woodward 8923‑1633 is a specialized control module that functions as both a programmable logic controller (PLC) and a synchronizer for three‑phase AC generators. Its primary role is to ensure that a generator being connected to a running system matches voltage, frequency, and phase before closing the breaker, preventing damaging inrush currents and voltage fluctuations.

The module integrates seamlessly with Woodward EasyGEN‑3200 generator control systems, offering flexible input/output capabilities and reliable digital control. It is widely used in power generation plants, marine propulsion systems, and industrial automation platforms where precise synchronization and load sharing are critical.
