Side terminals

I. Product basic information

Brand model: Woodward (USA) 8440-1831, belongs to the easYgen3200-5 series of unit controllers

Origin: Original production from the USA

Net weight: ≈ 950g; Dimensions: 280×130×60mm (embedded on the panel for installation)

Power supply: DC 12/24V, wide range of working voltage 8-40VDC, maximum power consumption of the entire machine 14W

Core hardware parameters

Display: 4.5×3.5-inch monochrome LCD screen + side soft buttons, local parameter settings, data viewing, fault alarm display

Analog quantity (FlexIn universal input ×3 channels): compatible with 4-20mA, 0-5V, VDO resistance type oil temperature/oil pressure sensors, no need for additional signal isolation module

Switching quantity IO: 10 non-polar digital inputs + 11 isolated relay outputs (control starter, closing and opening, stop electromagnet valve)

Power collection: CT current 0.5A secondary, PT voltage 100-400VAC, suitable for 50/60Hz (sampling 40-85Hz)

Communication interface: CANopen (unit parallel operation) + Modbus-RTU (remote transmission DCS/SCADA), load distribution among multiple machines is achieved through CAN bus communication

Core functions (for power generation)

Single machine control: diesel/gasoline unit automatic start/stop, closed-loop speed regulation, oil pressure/oil temperature/overcurrent/overvoltage comprehensive protection, fault shutdown alarm

ATS mains power switching (AMF): automatic startup of the unit when mains power is lost, automatic tripping and shutdown when mains power is restored, automatic switching between dual power sources

Multi-unit parallel grid connection: synchronization of multiple units, automatic distribution of active/ reactive load, grid disconnection control, main configuration for power plants/backup power stations

Remote monitoring: upload voltage, current, power, oil temperature, speed, fault code to the upper-level central control system

Application scenarios

Backup diesel/gasoline power units for industrial and mining, mobile power stations for oil fields, main and auxiliary power units for ships, backup power supply for data centers UPS, distributed biogas power stations
