8440-1884 M digital controller

The 8440-1884 M is a digital controller manufactured by Woodward that belongs to the easYgen-2000 family and features a variety of advanced features such as fuel efficiency optimization and remote control.
The controller is widely used in the field of control and protection of generator sets, suitable for various types of generator sets, such as diesel generator sets, natural gas generator sets, wind turbine sets and so on. It can detect the voltage, current, frequency and power factor of the generator set, and realize the control and regulation of the output voltage, current, frequency and power factor of the generator set. At the same time, the controller also has a variety of protection functions, which can realize the detection and protection of undervoltage, overvoltage, underfrequency, overfrequency, overload, short circuit and other faults of the generator set, ensuring the safe and reliable operation of the generator set.

In addition, the 8440-1884 controller is available in a variety of operating modes such as automatic, stop, manual, load test and no-load test modes. It also has circuit breaker control functions such as monitoring, slip frequency synchronization, phase match synchronization, and on-off control. In terms of load transfer, it can realize interchange, on/off conversion, power parallel, soft load and unload. The controller can also use coolant temperature or a timer to control preheating.

The controller is designed for use in three-phase alternators equipped with Woodward or other compatible speed control and automatic voltage regulators. It provides automatic frequency, phase and voltage matching using analog or discrete output bias signals. In addition, it has data logging capabilities and built-in redundant Ethernet communication ports.
