DS200SLCCG1AGH Product Description

Description

The DS200SLCCG1AGH is a dual-protocol LAN communication card developed by General Electric (GE) for the Speedtronic Mark V turbine control system—a cornerstone platform for managing gas, steam, and combined-cycle turbines in power generation, oil & gas, and heavy industrial sectors. It serves as the “data synchronization hub” for real-time communication between the Mark V’s core control modules (e.g., CPU, drive cards) and external systems (SCADA, operator workstations, or auxiliary drives), while supporting legacy industrial networks to ensure compatibility with aging infrastructure.

Distinguished from single-protocol cards, DS200SLCCG1AGH integrates dedicated circuits for both DLAN (Drive Local Area Network) and ARCNET (Attached Resource Computer Network), addressing the challenges of mixed-network environments where newer Ethernet-based systems coexist with legacy ARCNET equipment. Its modular design includes a LAN Control Processor (LCP) and dual-port RAM for seamless data synchronization, while isolated communication channels shield signals from electromagnetic interference (EMI) common in turbine halls. As a ruggedized Field-Replaceable Unit (FRU), it ensures reliability in extreme industrial conditions and simplifies maintenance with hot-swappable functionality.

Application Scenarios

A 400MW combined-cycle power plant in Louisiana faced recurring communication failures due to EMI interference and protocol fragmentation. Legacy single-protocol cards caused 1–2 monthly “data dropout” events, delaying turbine load adjustments and leading to $120,000 in annual downtime costs. Additionally, separate DLAN and ARCNET networks required redundant maintenance, tying up $35,000 in spare parts inventory.

After upgrading to DS200SLCCG1AGH, its dual-protocol support consolidated networks into a unified system, eliminating data dropouts entirely. The card’s 1500V AC isolated circuits reduced EMI-induced corruption by 98%, cutting false alarms by 90%. In Q1 2025, real-time data transmission detected a 1.2Hz 异常振动 in the steam turbine’s generator bearing 15 minutes before failure, enabling a planned shutdown and avoiding $450,000 in repair costs. Over 12 months, the plant avoided $1.3 million in downtime losses and reduced network maintenance labor by 70%.

Technical Principles and Innovative Values

Dual-Protocol Network IntegrationUnlike legacy single-protocol cards (e.g., DS200SLCCG3ADC), DS200SLCCG1AGH natively supports both DLAN and ARCNET, eliminating the need for external protocol converters. This reduces data latency from 500ms to <50ms, enabling real-time synchronization between legacy drives and modern SCADA systems. A refinery in California used this feature to optimize fuel valve adjustments, improving combustion efficiency by 1.5%.

Isolated Communication CircuitsThe card’s 1500V AC isolation ensures robust signal integrity in high-noise environments. A coal-fired plant in Pennsylvania reported a 99% reduction in “communication timeout” faults after upgrading, as EMI from nearby motors no longer corrupted data between the Mark V CPU and drive control cards.

Local Configuration via KeypadLegacy cards required laptop-based software for setup, but DS200SLCCG1AGH supports an attachable 16-key keypad for on-site parameter adjustment (e.g., network baud rate, node IDs). A hydroelectric plant in Colorado cut network configuration time from 2 hours to 20 minutes during maintenance outages, saving $30,000 annually in labor costs.

Hot-Swappable Rugged DesignAs an FRU, the card can be replaced without shutting down the turbine control system. A natural gas plant in Wyoming swapped a faulty unit in 10 minutes during peak operation, avoiding a $90,000 unplanned shutdown. Its rugged construction (IP54-rated) also withstands harsh conditions, with a 5-year mean time between failures (MTBF) in offshore applications.

Application Cases and Industry Value

Combined-Cycle Power Plant (Louisiana, U.S.)The 400MW plant’s fragmented networks caused data dropouts and high maintenance costs. After installing DS200SLCCG1AGH, its dual-protocol support and EMI isolation eliminated downtime, and predictive vibration monitoring avoided a $450,000 bearing failure. Over 12 months, turbine availability rose from 92% to 98.5%, adding $720,000 in annual generation value.

Petrochemical Refinery (Texas, U.S.)A refinery’s 250MW process steam turbine relied on ARCNET-only cards incompatible with a new DLAN-based emissions monitoring system. DS200SLCCG1AGH enabled seamless data sharing between the Mark V system and EPA-mandated sensors, ensuring compliance without a $250,000 network overhaul. Its wide temperature tolerance (65°C operation) also extended service life to 60 months, compared to 24 months for legacy cards.
