Designed for troubleshooting and backward compatibility, both models support reverse engineering capabilities. Specifically, the 9905-797 excels in dead bus closure operations. 

The Woodward 9905-797 is a sophisticated Digital Synchronizer Load Control Module designed to provide precise and reliable control in industrial applications requiring synchronization and load sharing between power sources. This module is engineered to deliver high-performance functionality in environments where maintaining the stability and efficiency of electrical systems is critical. As a product of Woodward, a leader in industrial control technologies, the 9905-797 module combines advanced features with robust design, making it an essential component for ensuring optimal power management in complex systems.

The 9905-797 module is specifically designed to handle two analog inputs and two channels, offering versatility in managing multiple power sources. This capability is crucial for applications that require the synchronization of generators or other power-producing equipment, ensuring that these sources operate in harmony to prevent system imbalances and power disruptions. The ability to manage two channels allows for more complex configurations, providing users with the flexibility to tailor the module’s operation to meet the specific needs of their application.

Operating on a 24 Vdc input voltage, the 9905-797 module is compatible with standard industrial power supplies, ensuring seamless integration into existing systems. The module is designed to handle a maximum operating current of 12 V, which provides sufficient power for its internal operations without imposing excessive demands on the system’s power resources. This efficient power usage is a testament to the module’s design, which emphasizes reliability and performance while minimizing energy consumption.

One of the key features of the 9905-797 is its wide operating temperature range, which extends from -40°C to +85°C. This broad range allows the module to function reliably in a variety of environmental conditions, from extreme cold to intense heat. Whether installed in outdoor settings, harsh industrial environments, or temperature-sensitive applications, the 9905-797 is built to perform consistently and reliably, ensuring continuous operation and minimizing the risk of temperature-related failures.

The module’s signal input impedance is rated at 33K Ohms, providing high resistance to interference and ensuring accurate signal processing. This high impedance is critical for maintaining the integrity of the analog inputs, allowing the module to accurately interpret and respond to input signals without distortion or degradation. This feature is particularly important in environments with high levels of electrical noise, where maintaining signal clarity is essential for reliable operation.

The 9905-797 is equipped with a 24-character LED display, providing clear and concise information about the module’s operational status. This display allows operators to quickly assess the module’s performance and make necessary adjustments, enhancing the overall usability of the system. The LED display is designed for easy readability in various lighting conditions, ensuring that critical information is always accessible.

In addition to its standard operational features, the 9905-797 module includes robust power supply transient protection, rated at 900 Vdc. This protection safeguards the module against voltage spikes and surges, which are common in industrial power systems and can cause significant damage to electronic components. By providing this level of protection, the 9905-797 ensures long-term reliability and durability, reducing the risk of downtime and extending the module’s operational life.

In summary, the Woodward 9905-797 Digital Synchronizer Load Control Module is a high-performance, reliable component designed to manage the synchronization and load control of power sources in industrial settings. With its two analog inputs, two channels, 24 Vdc input voltage, wide operating temperature range, and advanced signal processing capabilities, this module offers the flexibility and precision needed for complex power management applications. The inclusion of a 24-character LED display and robust transient protection further enhances its value, making the 9905-797 an essential tool for ensuring the stability and efficiency of electrical systems in demanding environments.
