Both the GE DS215DMCBG1AZZ03A and DS200DMCBG1AKG are circuit boards of the Mark V series, designed for steam turbine control systems. The DS215DMCBG1AZZ03A, as a driver board, features a densely populated layout with various connectors, jumper switches, and a comprehensive set of integrated circuits. It represents an upgrade over its predecessor (DS200 series) with enhanced hardware and firmware. The DS200DMCBG1AKG functions as a processor board, equipped with multiple pin connectors, LED indicators, and a reset switch. Its functionality can be configured via jumpers. Both boards utilize standard PCB coatings for basic protection, playing pivotal roles in signal processing and transmission within turbine control systems.
Features
High-Density Integrated Design
Equipped with over 55 integrated circuits (ICs), including FPGAs, EPROM storage chips, and oscillator circuits, enabling complex control algorithms and data processing.
Features 5 vertical cable connectors (4 male, 1 female), 3 plug connectors, and 3 piercing connectors for multi-channel signal transmission.
Modular Configurability: 20+ jumper switches allow flexible configuration to adapt to diverse turbine control scenarios (e.g., emergency trip systems, speed regulation). Onboard auxiliary control outputs (e.g., relay drivers) and LED status indicators facilitate real-time monitoring.
Enhanced Protection Design: Utilizes "G3"-grade standard PCB coating to resist dust and mild corrosion in industrial environments.
Integrated metal oxide varistors (MOVs) protect relays, improving surge resistance.
Technological Iteration & Upgrade: Optimized firmware algorithms and hardware architecture compared to the DS200 series, supporting higher-frequency signal processing and faster response times.
