Overview

The Woodward 9905-092 Import‑Export Control Module is a microprocessor‑based controller designed to manage power flow between utility grids and generator systems. It provides seamless import/export control, ensuring stable operation when paralleling generators with utility power.

Moreover, it integrates with Woodward’s DSLC (Digital Synchronizer and Load Control) and MSLC (Master Synchronizer and Load Control) systems, enabling complete automation of multi‑generator installations.

In addition, the module supports automatic synchronizing, bumpless load transfer, and reactive power management, making it ideal for industrial facilities, utilities, and marine applications.
