Manufacturer: GE General Electric / GE Gas Power
Part Number: DS200DMCBG1AKG (DOS DUP Main CPU Card, Rev:1A, PCB Rev:G, KG suffix full variant)
Product Type: Rack plug-in dual redundant DOS-based turbine main processor board, core computing master card of Mark V control rack
Matching Platform: GE Speedtronic Mark V electro-hydraulic turbine control system, gas turbine / steam turbine / combined cycle power plant control cabinet
Core Function: Dual redundant real-time DOS operating system turbine control algorithm operation, analog/digital I/O data scheduling, ARCNET internal rack communication, turbine speed/load/temperature closed-loop control, safety protection logic execution, fault self-diagnosis, jumper configurable function definition, local status LED indication, manual reset button for fault recovery
1. Product Overview
DS200DMCBG1AKG is the core dual redundant DOS DUP processor master board of GE Speedtronic Mark V turbine control system, serving as the central computing unit for gas, steam and combined cycle turbine closed-loop control and safety protection.
Adopts dual CPU hot standby redundant architecture running embedded real-time DOS system, independently executing turbine speed regulation, load control, exhaust temperature limit, flame detection, emergency trip protection and interlock logic algorithms. It schedules data interaction between all I/O cards in the Mark V rack via internal ARCNET bus, collects CT/VT analog sampling signals and discrete switch DI/DO signals, and outputs servo valve control commands to regulate turbine operating conditions.
The board carries abundant hardware configuration: 26×40pin multi-signal connectors, 19×2pin auxiliary connectors, nearly 200 configurable jumpers for function matching, dual status LED indicators (CR1/CR2), and a physical reset button for local fault reset without rack power cycle. Jumpers can adjust signal definition, communication address and protection logic parameters; only factory reserved jumpers are prohibited from field modification.
Full conformal coated PCB design with anti-corrosion, anti-moisture and dustproof performance, suitable for long-term stable operation in high EMI power plant cabinet environments. It cannot operate alone and must be matched with Mark V rack backplane, power supply module, analog input board, digital I/O board and communication card to form a complete turbine control unit.
This model belongs to legacy discontinued spare parts for old Mark V turbine units, mainly supplied as refurbished, surplus and remanufactured boards for power plant overhaul and replacement.
