GE IS420UCSCH2A-E-V0.1-ACPU Control Module
GE IS420UCSCH2A-E-V0.1-ACPU
1. Product Overview
The GE IS420UCSCH2A-E-V0.1-A is a dual-core CPU control module integrated into the GE Speedtronic Mark VIe steam turbine control system. As a high-performance processing and control unit of the Mark VIe distributed control system, it is mainly responsible for executing turbine control logic, managing I/O communication, and coordinating system protection functions, delivering high reliability and deterministic performance. Serving as the third-generation digital turbine control system developed by GE, it inherits the classic Triple Modular Redundancy (TMR) technology for steam turbine control.
