9907-1183
Main features and advantages:
Choosing the WOODWARD 9907-1183 delivers tangible operational benefits that extend beyond basic communication. Its robust isolation ensures that voltage spikes or surges in high-voltage systems—common during switching operations—do not propagate to control networks, reducing the risk of damage to PLCs or SCADA components. This protection translates to lower maintenance costs and fewer unplanned shutdowns, as critical control equipment remains shielded from electrical disturbances.
The module’s support for IEC 61850, the global standard for power system communication, eliminates protocol compatibility issues, reducing engineering overhead during system integration. Engineers no longer need to develop custom translation software, as the WOODWARD 9907-1183 natively handles the data formats required by both control systems and high-voltage devices. Additionally, its dual redundant ports ensure that communication remains uninterrupted even if a network cable fails or a port malfunctions—a key advantage in applications like renewable energy plants, where downtime can result in significant revenue loss. The module’s wide operating temperature range further ensures reliable performance in harsh environments, from unheated outdoor switchyards to temperature-fluctuating industrial facilities.

Application areas:
The WOODWARD9907-1183 is deployed in a range of critical applications where high-voltage communication is paramount. In renewable energy plants—such as solar farms or wind parks—it connects the central control system to high-voltage inverters and grid-tie transformers, enabling real-time monitoring of power output and grid synchronization. Its robust isolation is particularly valuable here, as inverters often generate electromagnetic noise that can disrupt standard communication links.
In power distribution networks, the WOODWARD 9907-1183 facilitates communication between SCADA systems and high-voltage switchgear, allowing operators to remotely monitor breaker status, trip signals, and load currents. This remote visibility reduces the need for on-site inspections, enhancing safety by minimizing exposure to high-voltage equipment.
In large manufacturing facilities with on-site power generation, the module connects the plant’s DCS to high-voltage generators and transformers, ensuring seamless coordination between production processes and power supply. Its ability to operate in extreme temperatures makes it suitable for steel mills, chemical plants, or refineries, where ambient conditions are often harsh.

Installation and maintenance:
Before installing the WOODWARD 9907-1183, verify that the control side power supply delivers a stable 24 V DC within the ±15% tolerance; voltage fluctuations can cause communication errors. Ensure the mounting location provides adequate airflow, as the module dissipates heat during operation—prolonged exposure to ambient temperatures above 65°C may reduce lifespan. Check that the high-voltage side wiring is properly insulated and rated for the system’s voltage (up to 36 kV), and confirm that communication cables are shielded and grounded to minimize noise pickup. It’s critical to validate protocol compatibility with both the control system and high-voltage equipment; Woodward provides a protocol compatibility matrix to streamline this process. Finally, ensure firmware on connected devices is up-to-date to support seamless integration with the9907-1183.
For ongoing maintenance, perform monthly checks of the module’s status LEDs: a steady green light indicates normal operation, while flashing amber signals a communication warning, and red denotes a critical fault requiring immediate attention via Woodward’s diagnostic software. Every six months, inspect electrical connections for corrosion or looseness, focusing on terminal blocks in humid or dusty environments. Test the redundant communication paths quarterly by temporarily disconnecting one port to confirm automatic failover—this ensures redundancy works when needed. Calibration of isolation barriers is recommended every two years, using Woodward’s specialized test equipment to verify continued compliance with safety standards. Finally, update the module’s firmware annually to access the latest security patches and protocol enhancements.
