The GE IS200ICIAH1A is an Innovation I/O Board (ICIA), which is a key Printed Circuit Board (PCB) in General Electric’s high-performance industrial control systems.
It is primarily used within the GE Mark VI Speedtronic Turbine Control System and the GE EX2100 Excitation Control System.
⚙️ Core Function and Role
The IS200ICIAH1A serves as the main I/O interface for specific signal types, bridging the gap between the field devices (sensors and actuators) and the core control processor.
-
Dedicated I/O Interface: The board is designed to process and condition a specific set of input/output signals before they are passed to the central control module (e.g., the $\text{UCSx}$ or $\text{ERAx}$ boards).
-
Signal Conditioning: It likely includes circuitry for signal conditioning, filtering, and isolation to ensure the field signals are clean and reliable for the digital controller.
-
System Integration: It plugs into the main control cabinet backplane and works in conjunction with the Innovation Control Base Card ($\text{ICBD}$) to distribute and collect signals from the external control packs.
-
Connectors: The board features multiple high-density connectors (often 96-pin ports) for connecting to I/O packs or terminal blocks that handle the actual field wiring.
-
Revision: The suffix H1A indicates the base hardware revision of this Innovation I/O Board.
In summary, the IS200ICIAH1A is vital for the acquisition and distribution of control data within the GE Mark VI and EX2100 architectures, ensuring that the controller receives accurate real-time information and can send timely commands to the field.
