WOODWARD 9907-164 Digital Microprocessor-Based Steam Turbine Controller

Product Description

The WOODWARD 9907-164 is a high-performance digital microprocessor-based controller designed for precise control and monitoring of steam turbines, gas turbines, and turbine-driven generators. As part of Woodward’s 505/505E governor control series, it ensures optimal operation through advanced microprocessor technology, supporting speed control, load regulation, and synchronization in industrial applications.

Key Features and Technical Specifications

1. Control and Monitoring

   • Supports speed control, load regulation, and synchronization in isochronous mode for parallel operation of multiple units.

   • 16 contact inputs (4 dedicated and 12 programmable) and 6 programmable 4-20mA current inputs for flexible signal processing.

   • Two-line, 24-character display for real-time monitoring of critical parameters such as speed, temperature, pressure, and power.

2. Safety and Protection

   • Built-in self-diagnosis for detecting overspeed, overheating, and overload conditions.

   • Critical speed avoidance, valve limiters, and emergency shutdown to prevent equipment damage.

3. Communication and Integration

   • Supports RS-232, Ethernet (Modbus), and CANbus for seamless integration with DCS, PLC, and SCADA systems.

   • 30-key multifunctional keypad for on-site programming and parameter adjustment.

4. Physical and Environmental Specifications

   • Dimensions: 15.2cm × 5.1cm × 20.3cm

   • Weight: 0.7kg

   • Power Supply: +24V DC, 1A

   • Operating Temperature: -20°C to +60°C

   • Protection Rating: IP56 (dustproof and water-resistant)

   • Certifications: CE, UL, compliant with Class I, Division 2 hazardous environments (with optional enclosure).

Advantages and Benefits
