IS420UCPAH2A GE Module Parts Mark VIe Controller with Integral I/O
The GE IS420UCPAH2A is an Integral I/O Controller Platform manufactured by General Electric (GE) for the Mark VIe turbine control system. It is designed to execute application control logic, process field signals, and communicate with external I/O modules through a simplex IONet network.
Compared with the IS420UCPAH1A, the IS420UCPAH2A includes an additional I/O expansion board, providing more analog inputs, analog outputs, and digital I/O channels.
The controller consists of three main hardware components:
- IS400BPPCH2A – Processor Board
- IS400STWCH1A – Base I/O Board
- IS400WEXPH1A – Expansion I/O Board
