Product Overview

• Part No: SDK-C0147, 12004-101-00, SBS04M17C
• Brand: ALSTOM (subsequently GE Grid Solutions)

• Category: SBS Serial Bus Station Control ModuleSDK-C0147 12004-101-00 SBS04M17C is a standard Eurocard draw-out serial bus controller developed for ALSTOM legacy turbine control platforms. It acts as a station master unit for SBS serial bus architecture, managing data communication between main controllers and distributed I/O sub-modules. The module processes real-time field signals, executes data forwarding, signal conditioning and communication protocol conversion. Equipped with multi-channel serial interfaces and on-board self-diagnosis circuits, it maintains stable data transmission under heavy electromagnetic interference in power plant control cubicles. It is a discontinued original spare part widely used for maintenance and retrofit of thermal power turbine governing systems.
