Functional Description
IC3600SDCA1B1B is a PCB Board developed by GE. It is a part of Mark I and II control system. Although GE has since developed more advanced control systems like the Mark V, Mark VI, and Mark VIe, many facilities around the world still operate turbines controlled by Mark I and II systems. As such, SDCA1B1B remains an important component for maintaining and servicing these legacy system.
Self-Checking and Protective Features of the System
- The turbine control system is specifically designed to be self-checking, ensuring that any critical failure is detected promptly to maintain both operational reliability and equipment safety.
- During startup procedures, the system automatically verifies the integrity and functionality of essential protective components such as:
- Flame detectors (to confirm proper combustion),
- Overspeed protection systems (to prevent turbine overspeed conditions),
- Overtemperature protection systems (to avoid thermal damage).
- If the system detects a failure in any one of the redundant protective components during startup, the startup sequence will be immediately aborted. This early detection prevents unsafe conditions from developing during operation.
- During normal running conditions, if a failure of one redundant protective channel occurs, the system will issue an alarm to notify operators of the problem. However, the unit will continue running because redundancy ensures that at least one protective channel remains functional. This approach enhances high running reliability, minimizing unnecessary shutdowns due to single-point failures.
- If a failure of both protective channels is detected while running, the system will initiate an immediate and safe shutdown of the turbine. This dual-channel protection philosophy ensures that safety is never compromised, even in the rare case of a total system failure.
- Beyond turbine-specific protections, the system also addresses the protection of the driven load (the equipment connected to the turbine), which may have its own set of protective requirements, such as:
- Vibration monitoring (to detect mechanical imbalances or failures),
- Low lubricating oil pressure detection (to prevent bearing damage),
- Electrical relaying for generator-driven systems (to safeguard electrical equipment),
- High gas compressor temperature monitoring for compressor-driven applications (to avoid thermal damage to compressors).
- Furthermore, the control system itself is protected against internal failures. For example, in the event of a power supply failure within the control system, the turbine will be brought down in a safe and controlled shutdown. This ensures that the loss of control infrastructure does not result in uncontrolled turbine behavior or equipment damage.

FREQUENTLY ASKED QUESTIONS
What is IC3600SDCA1B1B?
It is a PCB Board developed by GE.
What happens if a protective component fails during startup?
If any redundant protective component fails during startup, the system will immediately abort the startup sequence to prevent unsafe operating conditions.
What happens if a protective component fails during normal operation?
If one of the redundant protective channels fails during normal operation, an alarm is issued to alert the operators. The turbine continues running safely, as the remaining functional channel, and this ensures high reliability without unnecessary shutdowns.
