Description
Technical Specifications:
- Brand: Woodward
- Model: 8440-1713D
- Product Type: Digital Speed Controller
- Minimum Order: 1 Piece
Functional Features:
- Flexible Signal Input: Accepts 4-20mA or 1-5Vdc computer control signals for remote speed or load setting.
- Multiple Control Modes: Supports both isochronous regulation (constant speed) and droop regulation (load sharing in parallel operations).
- High-Precision Output: Delivers proportional analog output signals to accurately drive fuel valves and servo motors.
- Advanced Protection: Includes fuel-limited overspeed start and comprehensive engine protection logic.
Application Scenarios:
Ideal for generator sets, compressor stations, pump stations, and marine main engines requiring precise speed and load management.
Performance Parameters:
- Power Supply: 12/24 Vdc
- Operating Temperature: -20°C to 70°C
- Communication: RS-232/485, Modbus, Ethernet, SAE-J1939
Material Composition:
Constructed with industrial-grade electronic components and conformal-coated circuit boards to resist moisture, dust, and chemical exposure.
Structural Features:
Features a built-in HMI with a color LCD and soft keys, protected by multi-level passwords to prevent unauthorized parameter changes. Dimensions are approximately 16 cm × 16 cm × 12 cm.
Working Principle:
Receives real-time speed feedback from magnetic or Hall effect sensors. The microprocessor compares this feedback against the setpoint and executes PID algorithms to adjust the fuel actuator, maintaining exact engine speed under varying loads.
Installation Requirements:
Install in a clean, dry control panel. Shielded cables are strictly required for speed sensor and actuator wiring to prevent signal noise.
Usage Precautions:
Perform a thorough PID tuning and actuator calibration before placing the engine into commercial service. Regularly inspect the actuator linkage for mechanical binding.
