Communication Interface CANopen, RS232, optional Modbus RTU, connect to upper-level SCADA / unit main control

Operating Temperature Range -40℃～+70℃, applicable to ship / oilfield wide-temperature working conditions

Installation DIN35 rail clip installation, plastic shell modular

Core Functions

High-precision PID closed-loop speed regulation

Collect engine MPU speed signal, compare with set speed, output current to regulate throttle actuator; steady-state speed control accuracy ≤ ±0.25%, excellent dynamic speed stability under sudden load addition and removal.

Load sharing of generator sets

In parallel operation conditions, receive bus power signal, multiple units automatically divide kW active power, compatible with multi-unit parallel vehicle power station.

Safety Protection Logic

Built-in overspeed shutdown, under-speed alarm, speed break signal protection, passive contact output fault signal to unit alarm circuit.

Remote parameter setting

Serial port connected to debugging software, online modification of speed, gain, dead zone, slope ascending and descending speed parameters.

Applicable Scenarios

Fixed diesel / gas generator sets: factory self-contained power station, data center backup power supply, distributed cogeneration;

Marine auxiliary generator sets: engine room power control of ocean-going ships (DNV ship classification certification of the same series);

Internal combustion engine generator sets in oil and gas fields: gas engine compressor matching speed regulation;

General models of the same series: 8440-14XX, 8440-15XX, 8440-19XX, full series pin compatibility replacement. Woodward 8440-1409 Speed Controller Module
