Product Overview
The GE DS3800HMPK1 is a high-performance microprocessor board designed for GE’s Mark IV turbine control systems, serving as the computational backbone for real-time data processing and inter-module coordination. Engineered to manage critical control functions in power generation, oil & gas, and heavy machinery applications, this board processes sensor inputs, executes control algorithms, and interfaces with peripheral modules to ensure precise turbine operation.
Featuring a modular design with retention levers and a 34-pin Augat connector, the GE DS3800HMPK1 enables quick installation and secure connectivity within control racks. Its dual-sided layout includes three red status LEDs and one amber diagnostic LED, providing real-time visual feedback on power integrity, signal quality, and thermal health. The board integrates a single-core microprocessor and EPROM modules for storing control logic, ensuring reliable performance in high-vibration environments typical of industrial settings 1.
As part of GE’s Mark IV ecosystem, the GE DS3800HMPK1 interfaces seamlessly with other Mark IV modules (e.g., DS3800HPIB panel interface boards and DS3800NVCD digital control boards), enhancing system scalability. Its rugged construction includes surge protection and EMI-resistant shielding, making it suitable for electrically noisy environments like refineries and power plants. The board supports dual power inputs (24 V DC ±10% and AC via circuit breakers), ensuring continuous operation in mission-critical scenarios 1.

Key Features and Advantages
Real-Time Control Processing: The GE DS3800HMPK1’s embedded microprocessor executes control algorithms at sub-millisecond speeds, ensuring rapid response to turbine speed fluctuations, fuel flow adjustments, and safety-critical events. Its EPROM-based logic storage allows for easy firmware updates to adapt to evolving operational requirements 1.
Rugged Industrial Design: Shielded connectors and surge protection circuits safeguard against electromagnetic interference (EMI) and voltage spikes, ensuring stable performance in harsh environments. The board’s retention levers and modular design facilitate secure installation and minimize vibration-related failures in high-mechanical-stress settings like gas turbine control rooms 1.
Proactive Diagnostics: Four status LEDs provide instant visual feedback on power integrity, signal quality, and thermal health, enabling technicians to identify and resolve faults before they escalate. This predictive maintenance capability reduces mean time to repair (MTTR) by up to 30%.
Seamless System Integration: As part of GE’s Mark IV platform, the GE DS3800HMPK1 interfaces directly with GE’s DS3800HPIB panel boards and DS3800NVCD control modules, enabling unified control over turbine startup, load balancing, and emergency shutdowns. Its compatibility with legacy systems makes it ideal for retrofitting projects.
Dual Power Supply Redundancy: The board supports both DC (via system power) and AC (via circuit breakers) inputs, ensuring continuous operation even during partial power outages. This redundancy is critical in mission-critical applications where downtime is costly.
Application Areas
The GE DS3800HMPK1 excels in industrial applications requiring reliable microprocessor control:
- Power Generation: Serves as the computational core for gas and steam turbine control systems, managing speed regulation, generator synchronization, and exhaust emissions to optimize energy production and grid stability.
- Oil & Gas: Controls wellhead pressure, pump synchronization, and safety interlocks in offshore platforms and refineries, supporting predictive maintenance and regulatory compliance.
- Heavy Machinery: Monitors rotational speed, detects torque anomalies, and prevents equipment failure in mining crushers, conveyor systems, and industrial drives.
- Water Treatment: Executes control logic for chemical dosing pumps and sensor feedback in wastewater treatment plants, optimizing resource allocation and energy efficiency.
