Description
Woodward PCU2000ETHD
Technical Specifications
- Brand: Woodward
- Model: PCU2000ETHD
- Product Type: Programmable Turbine Controller
- Communication: Integrated Ethernet (Modbus TCP/IP, OPC)
- I/O Capacity: Scalable via plug-in I/O modules
Functional Features
- Network Integration: Native Ethernet port for high-speed data exchange and remote diagnostics.
- Advanced Control Logic: Supports complex PID, cascade, and ratio control algorithms for precise turbine management.
- Redundancy Support: Compatible with hot-standby configurations for critical power generation applications.
- Event Logging: High-capacity memory for storing operational trends and fault history.
Application Scenarios
Widely deployed in gas turbines, steam turbines, mechanical drives, and cogeneration plants requiring networked control and remote monitoring.
Performance Parameters
- Scan Time: Fast, deterministic execution for high-speed turbine protection and control.
- Network Latency: Minimal delay for real-time operator interface updates.
Material Composition
Constructed with a rugged metal enclosure, industrial-grade microprocessors, and conformal-coated printed circuit boards (PCBs) for environmental protection.
Structural Characteristics
Modular rack-mounted design featuring front-panel status LEDs, an Ethernet port, and a configuration interface.
Working Principle
Continuously acquires data from field sensors, executes the user-defined control program in a cyclic scan, and outputs commands to actuators while simultaneously managing network communication.
Installation Requirements
Mount in a NEMA-rated control panel with adequate ventilation. Use shielded CAT5e/CAT6 cables for Ethernet connections and ensure proper chassis grounding.
Usage Precautions
Always maintain a verified backup of the control logic. Assign static IP addresses and configure network firewalls to protect the controller from unauthorized access.
