The GE IS200ICIAH2A is an Innovation I/O (Input/Output) Board and a component of the General Electric Mark VI Speedtronic Turbine Control System.
The board is a specific revision or group of the base ICIA (Innovation I/O) module, designed to facilitate the interface between the main turbine control processor and the various field devices in a power generation environment.
⚙️ Key Details and Function
-
System Series: It belongs to the Mark VI IS200 product line, part of GE’s long-running Speedtronic series of gas/steam turbine management systems.
-
Function: Its primary role is to manage the I/O signals, acting as an intermediary to:
-
Receive and condition signals from sensors (e.g., pressure, temperature, position) connected via terminal boards.
-
Transmit control commands to actuators (e.g., valves, relays) to regulate turbine operation.
-
-
Form Factor: The board uses a VME (VersaModule Eurocard) mounting type, indicating it plugs directly into the backplane of a Mark VI VME rack system.
-
Protection: The IS200ICIAH2A is manufactured with conformal coating to protect its circuitry from challenging industrial environments, including exposure to moisture, dust, and electrical noise.
-
Revision: The “H2A” in the part number indicates it is a Group 2 board, and in the case of the IS200ICIAH2A, the artwork is an ‘A’ level revision, distinguishing it from other ICIA board revisions like the H1A group.
💾 Comparison with H1A Group
The main difference between the IS200ICIAH1A group and the IS200ICIAH2A group typically lies in the design revision (Group 1 vs. Group 2), which may involve minor changes to the board’s layout, component choices, or manufacturing process to enhance performance or address obsolescence. Both boards perform the same core function as the Innovation I/O controller in the Mark VI system.
