I/O modules

The Woodward 9905-007N is a specialized load control module for industrial generator applications. This unit precisely manages real and reactive power output from generating sets. Moreover, it ensures stable load sharing and frequency regulation within parallel operations.

Core Functionality in Power Management

This module actively controls the generator’s load in response to grid demands or isolated network requirements. It adjusts fuel or steam intake to balance power generation with consumption. Consequently, the system maintains consistent electrical frequency and stable voltage levels.

System Integration and Critical Applications

The Woodward 9905-007N is vital for power plants, marine vessels, and backup generation facilities. It works in concert with other Woodward control products, such as synchronizers and governors. For instance, it pairs with synchronization controls like the 9905-002N after a generator successfully parallels to the bus. This module is part of a comprehensive control ecosystem that may include protective devices like the RMS-TSG-TZ-C Static Trip unit. It also interfaces with system processors like the IS200AEBMG1AFB and monitoring sensors such as the PR6423/128-110.
