Description
GE DS3800HMPFIE1E Microprocessor Board
Product Overview
The GE DS3800HMPFIE1E is a high-performance microprocessor board engineered for GE’s Mark IV Speedtronic turbine control system, serving as the computational backbone for real-time data processing and inter-module coordination in industrial gas and steam turbine applications. As part of the Mark IV series, this board executes critical control algorithms, processes sensor inputs, and interfaces with peripheral modules to ensure precise turbine operation, making it indispensable for mission-critical environments in power generation, oil & gas, and heavy industry.
Designed with Triple Modular Redundancy (TMR) architecture, the GE DS3800HMPFIE1E uses three independent processors to vote on critical decisions, minimizing downtime and ensuring fault tolerance . This redundancy is particularly vital in applications where system failure could lead to costly disruptions. The board features a modular design with a vertical pin connector and four standoffs for optional daughterboard expansion, enabling scalable configurations to meet evolving operational needs. Its dual-sided layout includes over 50 integrated circuits, including PROM/EPROM modules for storing control logic, and supports RS-485 and Ethernet communication for seamless integration with other Mark IV components like I/O modules and HMIs .
Despite the Mark IV series being legacy technology, the GE DS3800HMPFIE1E remains a cornerstone for maintaining aging industrial infrastructure. Its rugged construction—with surge protection, EMI shielding, and a wide operating temperature range—ensures reliable performance in high-vibration, extreme-temperature environments typical of power plants and refineries .
