Modern industrial control systems demand seamless and high-speed communication between modules. Whether it’s a power plant turbine control system or a complex manufacturing line, real-time data transfer is essential for synchronized operation and efficiency. One key component that enables robust internal communication is the Serial Link Expansion Board. Designed to enhance inter-module connectivity, these boards make it possible to scale and customize control systems with ease. Among them, the IS200CSLAH1A Compact PCI Serial Link Expansion Board stands out as a reliable and high-performance solution, specifically engineered for GE Mark VI and VIe turbine control platforms.
What Is a Serial Link Expansion Board?
A Serial Link Expansion Board is a hardware module that enables additional serial communication pathways within a control system. Unlike standard communication interfaces, these boards use high-speed serial buses to facilitate direct connections between controllers, processors, and peripheral modules.
The IS200CSLAH1A is based on the CompactPCI (cPCI) standard—an industrial-grade bus interface derived from the traditional PCI used in computers but adapted for more rugged environments. CompactPCI supports hot-swapping, better mechanical durability, and high data bandwidth, making it ideal for mission-critical control systems.
These boards essentially allow systems to expand their communication capabilities without overhauling existing infrastructure, maintaining modularity while improving performance.
Purpose of IS200CSLAH1A in GE Systems
The IS200CSLAH1A is a specialized Serial Link Expansion Board used in GE’s Mark VIe control systems, often deployed in turbine control, power generation, and large industrial automation environments. Its primary function is to facilitate serial communication between different boards or processing units within a CompactPCI-based architecture.
It serves as a bridge for data exchange, especially in setups where multiple processors need to coordinate in real time. By using serial communication, the board minimizes latency and ensures fast, synchronized operations across distributed components.
Additionally, the board supports reliable, low-noise communication, which is critical in electrically noisy environments like those found in power plants or compressor stations.

FAQ
What does the IS200CSLAH1A actually do in a GE Mark VIe system?
The IS200CSLAH1A is a CompactPCI Serial Link Expansion Board designed to support high-speed serial communication between different modules in a GE Mark VIe turbine control system. It acts as a data bridge, enabling processors, I/O modules, and controllers to exchange real-time information efficiently. Without this board, the overall system would suffer from communication bottlenecks or limited expansion capabilities. It is especially important in applications that require coordinated control and synchronization—such as turbine startup, shutdown, and load adjustments—where precision timing is essential.
2. How does a Serial Link Expansion Board differ from a standard communication interface?
While standard communication interfaces (like Ethernet or RS-232) are typically used for broader data exchange between systems or external devices, Serial Link Expansion Boards are focused on internal communication between modules within the same control system. They use high-speed serial protocols that are optimized for low-latency, high-reliability data exchange, often over shorter distances and through backplane or direct connections. The IS200CSLAH1A specifically uses a CompactPCI (cPCI) bus, which supports modular designs and facilitates fast, secure inter-module communication without the delays and interference that may affect traditional interfaces.
3. Is the IS200CSLAH1A compatible with non-GE systems?
The IS200CSLAH1A is specifically designed for GE Mark VIe systems, and its full functionality is optimized for GE’s proprietary control infrastructure. While the board adheres to the CompactPCI hardware standard, which may be physically compatible with other cPCI-based platforms, it is not recommended to use the IS200CSLAH1A in non-GE environments due to potential firmware dependencies and compatibility issues. GE systems often require tightly integrated hardware and software components for diagnostics, configuration, and fault detection. Therefore, this board is best utilized within the intended GE ecosystem for optimal performance and system integrity.
4. What are common signs that the IS200CSLAH1A needs servicing or replacement?
Some common signs that the IS200CSLAH1A may need servicing include:
-
Loss of data communication between modules
-
Flashing or non-responsive status LEDs
-
System alarms triggered by communication faults
-
Unusual heating or signs of physical damage on connectors
-
Inconsistent system behavior, particularly during operations that require high-speed module coordination
If these symptoms appear, it’s crucial to run a diagnostic scan using GE’s control software tools. In some cases, reseating the board or checking for loose connectors can resolve issues. If hardware failure is confirmed, replacing the board with a verified spare is recommended.
5. Where is the IS200CSLAH1A most commonly used, and why is it ideal for those settings?
The IS200CSLAH1A is most commonly used in power generation plants, particularly in systems controlling gas and steam turbines managed by GE’s Mark VIe platform.
