GE IS200CSLAH4A HSSL Expander Card

The GE IS200CSLAH4A is a High-Speed Serial Link (HSSL) Expander Card manufactured by General Electric (GE) for the Mark VI Speedtronic Turbine Control System and its related auxiliary systems, such as the EX2100 Excitation Control Regulator System.

⚙️ Function and Role

This module is a crucial component for high-speed communication and expansion within the industrial control rack.

• HSSL Communication: The board’s primary function is to expand the High-Speed Serial Link (HSSL) communication interface. This enables efficient and reliable data transfer between control system components, which is essential for the precise, timely control of gas and steam turbine operations.
• Expander Card: It acts as an I/O Expander Card that works in conjunction with the main control processor board (such as the main control processor board in the EX2100 system).
• System Context: In redundant control systems (Triple Modular Redundant, or TMR), an IS200CSLAH4A board is typically used on each of the Control (C), Module 1 (M1), and Module 2 (M2) modules to maintain parallel, high-speed communication across all controllers.
• Technology: It is a double-sided printed circuit board (PCB) that utilizes components like HFBR-5961xxZ transceivers for Fast Ethernet or fiber optic communication, enabling high-speed data exchange.

System Integration

The IS200CSLAH4A is part of the extensive IS200 product line and is vital for systems that require integration between turbine control, excitation control (EX2100), Human-Machine Interfaces (HMIs), and static starter control systems.
