Technical Specifications
Power Supply and Environment
Power supply: 12/24 Vdc (8 to 40 Vdc range)
Burden: < 0.10 VA
Operation temp: -4°F to 158°F (-20°C to 70°C)
Front panel dimensions: 282W x 216H x 96D mm
Setting Range and Outputs
The 8440-2055 provides a wide setting range for current protection. Its relay outputs are fully isolated, ensuring safe switching in noisy environments.
Speed Input and I/O Overview
Speed measurement uses a magnetic or switching pickup with a 50/60 Hz measuring frequency. Furthermore, the 8440-2055 includes both discrete and analog I/Os. All I/Os are configurable. Ten out of twelve alarm outputs can also be customized to match your application.
Protection Coverage
Generator overload or unbalanced load
Engine overspeed or underspeed
Engine speed/frequency mismatch
Mains phase shift or rotation field issues
Moreover, numerous setpoints are configurable. This allows you to fine-tune protection thresholds for different sites, from data centers to industrial plants.
Four Operating Modes
Automatic Mode: The controller starts and stops the genset based on load or mains status.
Manual Mode: Operators control start/stop and load sharing directly.
Stop Mode: The engine shuts down immediately with alarms locked out.
Test Mode: You can simulate runs without connecting to the load.
Therefore, the 8440-2055 adapts to both unattended and operator-supervised installations.
Frequently Asked Questions (FAQ)
1. Can I use the 8440-2055 with a single genset only?
Yes. The 8440-2055 works for single units and multiple units. For parallel operation, it supports up to 32 gensets with the mains.
2. Does the 8440-2055 have a display screen?
No. This model has no built-in HMI. You need a PC with Woodward ToolKit software to configure and monitor the 8440-2055.
3. What happens if the DC supply voltage drops below 8 Vdc?
The 8440-2055 may reset or shut down. Always keep the supply between 8 and 40 Vdc. Use a stabilized power source for best results.
4. How do I update the firmware on the 8440-2055?
Firmware updates are done via ToolKit software over the communication port. Download the latest files from Woodward’s support site first.
5. Is the 8440-2055 suitable for marine applications?
