IC3600SSVF1C - Servo Valve Feedback Card

SPECIFICATIONS

Part No.: IC3600SSVF1C
Manufacturer: General Electric
Product Type: Servo Valve Feedback Card
Availability: In Stock
Series: VersaMax

Functional Description

IC3600SSVF1C is a Servo Valve Feedback Card developed by GE. It is a part of GE Mark I and II series. Designed to receive and process feedback signals from servo valves that control actuator movements. These feedback signals are compared to control signals issued by the Speedtronic system to ensure accurate and stable positioning. Any deviation between the desired and actual positions is corrected in real-time, enabling precise control of turbine performance and maintaining optimal efficiency and safety.

Features

• The Mark I system was built around a modular card-based design, where various circuit boards performed dedicated functions such as control, feedback, and protection. This architecture made maintenance and troubleshooting much easier, as faulty cards could be quickly replaced without affecting the entire system.
• A critical feature of the Mark I was its fail-safe and redundancy philosophy. It included dual trip paths to ensure that if one protective route failed, the turbine would still be safely shut down through another. In particularly critical areas like overspeed protection, even double or triple redundancy was incorporated to maximize reliability and operator safety.
• The Mark I integrated a comprehensive protection system into its design. It monitored vital turbine conditions such as overspeed, overtemperature, and lube oil pressure. If dangerous conditions were detected, the system would automatically trigger a shutdown to prevent damage or hazardous situations.
• Operators could interact with the turbine through an intuitive interface panel that provided clear visual indicators for various control modes like startup, temperature control, acceleration control, and speed governing. The system also supported both manual and automatic operation, giving operators flexibility depending on the situation.
• Another notable strength of the Mark I was its self-checking capability during turbine startup. Before allowing the turbine to fire, the system would verify that all essential sensors and protective devices were functional. If a fault was detected, such as a missing overspeed sensor or a broken wire, the system would prevent the turbine from starting, ensuring safe operation at all times.
• By controlling key loops such as fuel flow, turbine temperature, acceleration, and speed, the Mark I achieved stable and efficient turbine performance. Its robust and durable design made it highly reliable for continuous use, setting a standard that influenced future generations of Speedtronic control systems.

Frequently Asked Questions

What is IC3600SSVF1C?
It is a Servo Valve Feedback Card developed by GE.

Will the turbine keep running if there's a failure in one protection path?
Yes, in many cases, the turbine will continue to run if a single failure occurs, provided the other protection paths are functional. However, the failure will be annunciated to the operator, prompting inspection and repair.

What is meant by trip routes?
Trip routes are electrical or mechanical pathways through which a shutdown command can be sent. Having multiple trip routes ensures that if one fails, others can still initiate a turbine shutdown.
