Technical Specifications

The XD1G11 integrates galvanic isolation with multi-channel signal processing to maintain accuracy in electrically noisy environments.

Engineering Advantages

• High-Speed Fault Detection: The XD1G11 utilizes intelligent differential algorithms to identify internal winding faults within milliseconds. This rapid response triggers breaker trips before thermal or mechanical damage compromises the generator or transformer core.

• Galvanic Noise Immunity: Industrial power environments suffer from heavy electromagnetic interference. This module employs robust galvanic isolation across its input and output channels, filtering out high-frequency noise and preventing ground loops from corrupting critical sensor data.

• Versatile I/O Architecture: The module functions beyond a simple relay; it processes both digital and analog signals. This allows engineers to consolidate protection logic and general control I/O into a single hardware footprint, simplifying cabinet wiring and reducing total system cost.

• Seamless Network Integration: Integrated CAN and Ethernet ports allow the XD1G11 to communicate natively with Woodward turbine governors and DCS platforms. This enables remote diagnostics and real-time monitoring of protection parameters via standard industrial protocols.

• Extreme Durability: Designed for high-availability systems in marine propulsion and power plants, the XD1G11 withstands continuous operation in harsh industrial atmospheres. It maintains calibrated accuracy throughout its operational temperature range.

FAQs

Q: Can the XD1G11 protect both synchronous and asynchronous motors?

A: Yes. The XD1G11 provides differential protection for various rotating machines. You must configure the CT (Current Transformer) ratios and trip thresholds within the Woodward software to match the specific electrical characteristics of your motor or generator.

Q: How do I verify the communication status of the module?

A: The XD1G11 features integrated LED indicators that display the status of the Woodward control bus. A steady heartbeat or specific flash pattern confirms active CAN/Ethernet communication with the master controller.

Q: Does this module require external power, or is it bus-powered?

A: The XD1G11 typically draws its logic power from the Woodward rack backplane. However, certain field-side I/O channels may require an external 24 VDC supply to energize sensors or drive external relays. Always refer to your specific system wiring diagram.

Q: Is the XD1G11 a suitable replacement for older analog differential relays?

A: Absolutely. The XD1G11 offers significantly better precision, programmable trip curves, and digital logging capabilities compared to legacy analog hardware. It fits into standard Woodward distributed I/O slots for easy upgrades.
