GE IC4988A100AA MODULE

The GE part number IC4988A100AA is a Module. It’s a component of GE’s legacy Mark V Speedtronic turbine control systems. As a generic “Module,” it is a pre-packaged electronic unit that performs a specific, but not explicitly defined, function within the control cabinet. ⚙️

Function and Context

Without a more specific name, it’s not possible to know the exact function of the IC4988A100AA. However, its role within the Mark V system can be broadly understood:

• Digital Control: Unlike the older Mark I and Mark II systems that relied on analog control, the Mark V was a fully digital system that used microprocessors for control and protection logic. This module is an electronic card designed for use in the Mark V’s digital architecture.
• Modular Design: The Mark V system was built with a modular design, where a specific function (e.g., control, protection, or communication) was handled by an individual module. The module plugs into a rack and communicates with other cards via a backplane.
• Component of a Larger System: This module works in conjunction with many other modules to form the complete control and protection system for a turbine. Its function would be to perform a specific task within a control loop, such as a type of input/output (I/O) processing, communication protocol handling, or a specialized control function.

Applications

The IC4988A100AA is a legacy component, so it is primarily used in power generation facilities that still operate GE’s Mark V turbine control systems. It is an essential part of the control panel, ensuring reliable operation of the turbine by performing its specific function within the digital control architecture.
