WOODWARD 9907-167

1. WOODWARD 9907 – 167 505E Series Turbine Control Operator Interface Terminal Module
2. Product DescriptionThe WOODWARD 9907 – 167 is a dual – redundant operator interface terminal specifically developed for the 505E series digital turbine control systems. It is designed for front – panel mounting and serves as a crucial human – machine interaction hub for turbine operation.
3. This module offers a clear overview of the operating status of gas and steam turbines. It allows operators to conveniently monitor turbine performance and adjust relevant parameters through its configured pushbuttons and rotary switches. It is equipped with built – in program upload and download capabilities, facilitating users to update control logic and maintain the module.
   Housed in a NEMA 4 enclosure, the module is dustproof and moisture – proof. It can operate stably in harsh industrial environments such as power plants, oil drilling platforms and chemical factories. Additionally, it has excellent anti – vibration and anti – shock performance and integrates multiple protection mechanisms. When abnormalities like overspeed and overload of the turbine occur, it can cooperate with the main control system to trigger alarms promptly, which is essential for ensuring the safe and efficient operation of turbines and related power equipment.
