Product Features
- Triple Redundancy Architecture: It adopts a Triple-Redundant design internally to ensure the system can still operate safely in case of a single-point failure.
- Modular Structure: The CPU, I/O, communication, and power modules can all be replaced independently, facilitating on-site maintenance and function expansion.
- High-Precision Control: It supports multiple control algorithms such as closed-loop speed, position, and pressure, meeting the high-demand applications of power generation, compressors, gas turbines, etc.
- Rich Communication Options: It has built-in multiple industrial protocols, making it easy to integrate into DCS, SCADA, or upper-level computer systems.
- Diagnosis and Self-Inspection: It is equipped with real-time fault diagnosis, log recording, and remote monitoring functions to improve operation and maintenance efficiency.
Structure and Composition
- CPU/Control Unit: As the core processor, it executes control algorithms and manages I/O and communication.
- I/O Module: Provides analog input/output, digital input/output, and dedicated sensor interfaces.
- Power Module: Offers voltage stabilization, over-voltage/under-voltage protection, and supports a wide range of input voltages.
- Communication Module: Optional interface cards for RS-485, CAN, Ethernet, etc.
- Chassis/Panel: Complies with industrial protection classes, and is equipped with status indicator lights and a Human-Machine Interface (HMI) port.
Typical Application Fields
- Power plants (gas turbines, steam turbines, diesel generators)
- Oil and gas industry (compressors, pump stations)
- Industrial manufacturing (large motors, variable frequency drives)
- Marine and offshore engineering (propulsion systems, power generation systems)
- Military and aerospace (engines, auxiliary power units)
Installation Key Points
- On-Site Preparation: Ensure the cabinet or installation platform is flat and stable, and provide a power supply and grounding that meet the specifications.
- Wiring: Complete the correct connection of power supply, I/O, and communication cables according to the wiring diagram, and use protective sleeves to prevent electromagnetic interference.
- Chassis Fixing: Fix the module in the cabinet using bolts or buckles to maintain ventilation and heat dissipation.
- Software Configuration: Use the configuration tool provided by Woodward (such as Woodward Configurator) to set parameters, configure communication protocols, and download control strategies.
Maintenance Recommendations
- Regular Inspection: Check the power input, wiring tightness, and the working status of the cooling fan every 6 to 12 months.
- Firmware Upgrade: Timely update the firmware according to the official firmware version released by Woodward to obtain the latest functions and security patches.
- Fault Diagnosis: Use the built-in self-inspection function and log files to locate abnormalities. If necessary, replace the faulty I/O or power module (the modular design facilitates quick replacement).
- Environment Monitoring: Keep the temperature and humidity of the working environment within the rated range to prevent dust and corrosive gases from entering the chassis.
