Part Number: EGS-01
Brand: Woodward (Woodward Industrial Controls)
Product Category: Engine Governor Driver (Electromechanical Actuator Driver)
Product Series: Woodward EGS Series Engine Control Accessories
Core Application: Specifically designed for Woodward engine governor systems, widely applied in diesel/gas engines, generator sets, marine propulsion systems, construction machinery, and industrial power equipment. It is responsible for converting control signals into precise mechanical actuation, regulating engine speed, fuel injection quantity, and valve position, ensuring stable operation, speed synchronization, and load adjustment of engines under various working conditions.
Core Features: High-precision position control with closed-loop feedback; compatible with Woodward digital governors and PLC control systems; integrated speed detection and fault diagnosis functions; wide voltage adaptation for harsh industrial environments; strong anti-interference performance against vibration and electromagnetic interference; modular design for easy installation and maintenance; built-in overcurrent, overheating, and overload protection; support for manual/automatic control switching.
2. Electrical Specifications
Operating Voltage: 24V DC (wide voltage range: 18V DC ~ 32V DC), compliant with Woodward engine control power supply standards
Rated Operating Current: 2A (typical), 5A (peak, during actuation)
Power Consumption: ≤48W (typical), ≤120W (peak)
Control Signal Input: Analog input (0-5V DC, 4-20mA) for position/speed setpoint; Digital input (TTL level) for control mode switching and enable signal
Feedback Signal Output: Analog output (0-5V DC, 4-20mA) for position feedback; Digital output (TTL level) for fault alarm and status indication; Communication Interface: RS-485 (Modbus RTU) for data interaction with upper controller
