The GE IS200BLIGH1AAB is a highly specific Printed Circuit Board (PCB) known as the BIC LAN Interface Board (1$\text{BLIG}$).2 It is a key communication module for General Electric’s Mark VI Speedtronic Turbine Control System and its associated Innovation Series Drive applications.3
Its main purpose is to provide the high-speed network interface necessary for the Bridge Interface Controller ($\text{BIC}$) or drive system to communicate with the main turbine control network.
⚙️ Core Functionality and Features
The $\text{BLIG}$ board is an interface and communications component, not a central processing unit. The extended revision code, H1AAB, is critical for ensuring compatibility with the rest of the Mark VI system’s hardware and firmware configuration.
- Communication Interface: The board enables network communication, typically supporting a $10/100 \text{ Mbps}$ Ethernet connection, which is vital for the control system to send high-speed control commands and receive time-critical diagnostic and feedback data from the drive components.
- Module Integration: The 4$\text{BLIG}$ board often serves as a component of a larger module, such as the Auxiliary Genius BUS Interface Module (5$\text{IS215GBIAH}$) or the Auxiliary Profibus-DP Interface Module (6$\text{IS215PBIAH}$).7 In these configurations, it works alongside a secondary communications card (like a Profibus-DP board) to facilitate integration between the drive and the controller over different industrial networks.8
- Revision Coding: The suffix H1AAB details the revision:
- H1: Likely denotes a specific hardware revision or conformal coating.
- AA: Represents two functional revisions.
- B: Represents an artwork configuration revision.
- Diagnostics: The board is equipped with LED indicators on its front panel, typically labeled “OK” and “COMM OK” or “DIAGNOSTIC,” to provide local status on the board’s health and network communication.9
- Mounting: The 10$\text{IS200BLIGH1AAB}$ is designed for insertion into the VME Rack Mounting Assembly within the Mark VI control cabinet.11 It features a larger faceplate compared to some other $\text{IS200}$ series boards.
⚠️ Important Considerations for Replacement
- Exact Revision Match: The H1AAB revision is highly specific. Because this board handles network protocols and data integrity for safety-critical drive control, you must use an exact matching revision when replacing the board to guarantee system compatibility and reliable communication.
- Static Sensitivity: Handle the board using strict Electrostatic Discharge ($\text{ESD}$) procedures due to its sensitive electronic components.
