Description
Woodward 9907-165
Product Overview
The Woodward 9907-165 is a Digital Turbine Control Unit from the 505E series, designed for precise regulation of industrial steam turbines, particularly in applications requiring controlled extraction/admission pressure control. It integrates a 32-bit microprocessor with configurable software to manage critical parameters like speed, pressure, and load, making it suitable for power generation, oil & gas, and process industries. The module supports dual Modbus communication ports (ASCII/RTU) and features an optional NEMA 4X enclosure for harsh environments 89.
Key functions include:
- Speed control (0–100% range) with ±0.1% accuracy (implied by Woodward’s 505E series standards)
- Extraction/admission pressure regulation for steam turbines
- Auto-start sequencing and critical speed avoidance
- 2-out-of-3 trip logic for fail-safe operation
- Real-time diagnostics via a 2-line LED display and 30-key keypad
The 9907-165 interfaces with actuators, sensors, and auxiliary equipment through 16 digital inputs, 8 relay outputs, and 6 programmable analog I/O channels (4–20 mA/0–10 V), ensuring flexibility in complex control loops. Its -25°C to +65°C operating temperature range and IP65-rated enclosure (with NEMA 4X option) enable reliable performance in high-vibration or corrosive settings 12.

Key Features and Advantages
High-Precision Control: The 9907-165 delivers ±0.1% speed control accuracy, using adaptive algorithms to minimize overshoot during load transitions. Its dual-loop PID control supports both speed and pressure regulation simultaneously, critical for applications like extraction steam turbines .
Harsh Environment Resilience: With an IP66-rated enclosure (NEMA 4X), the module withstands salt mist, dust, and water ingress typical of offshore platforms or chemical plants. Conformal coating and surge protection (MOVs) further enhance reliability in high-EMI environments 14.
Flexible Integration: Seamless compatibility with Woodward’s 505E ecosystem allows integration with load sharing modules (e.g., 9907-173) and synchronizers (e.g., 9905-946), enabling grid synchronization and load balancing across multiple turbines. Its Modbus connectivity facilitates integration with DCS/PLC systems for centralized monitoring 26.
Safety-Critical Design: Certified to IEC 61508 SIL 2, the 9907-165 includes 2-out-of-3 trip logic to prevent false trips, along with first-out fault indication and real-time event logging. Emergency shutdown (ESD) inputs ensure rapid deactivation in hazardous conditions .
Predictive Maintenance: Built-in self-diagnostics monitor sensor health, communication integrity, and thermal performance. Integration with Woodward’s ProAct analytics platform enables condition-based maintenance, reducing mean time to repair (MTTR) by up to 30% 24.
