Engineered for GE Mark V Speedtronic Processing

This board serves as the dedicated ARC processor for turbine control calculations. It provides high-speed computational power for the GE DS200ACNAG1A DS200ACNAG1ACC module. You will find this processor board exclusively in the Mark V turbine control series. Unlike standard CPU boards, this version uses the “ACC” functional revision. It handles complex control algorithms for gas and steam turbines.

Technical Specifications & Physical Dimensions

We designed this ARC board for demanding real-time processing. The table below presents all verified technical specifications.

Functional Architecture and Data Processing

This ARC board communicates directly with the main turbine controller. It uses dual-ported RAM for high-speed data exchange. You can configure the board for various turbine control algorithms. Moreover, the board includes hardware watchdog timers for fault detection. These components reset the processor if software execution fails. Consequently, the system maintains safe turbine operation during rare processor faults.

Installation and Operational Guidelines

The GE DS200ACNAG1A DS200ACNAG1ACC executes one control cycle every 1 millisecond. It consumes 1.5A at 5V DC from the backplane. You must verify firmware revision before installing the board. Always use anti-static handling procedures during replacement. This practice prevents electrostatic damage to sensitive processor components. Furthermore, the board supports background self-diagnostics during normal operation. This feature detects memory errors and processor faults automatically.

Physical Characteristics and Environmental Limits

This ARC board has a high-density, multi-layer PCB design. Its moderate 0.46 kg weight allows for easy field replacement. The layout follows GE’s standard Mark V thermal specifications. Therefore, it fits securely into designated processor slots in the rack. The board includes a heat sink and status LED indicators. In addition, it maintains stable operation between 0°C and 55°C ambient temperature. You can store this unit safely up to 85°C.
