Product Overview:

The DS200LDCCH1AMA is a Drive Control and LAN Communications Board developed by General Electric for its Mark V Turbine Control System Series. As part of GE’s legacy Speedtronic-based control systems, this board integrates motor control, device I/O coordination, and LAN signal processing, and is compatible with DIRECTO-MATIC 2000 drives.

Although the DS200LDCCH1AMA is not the original LDCC board in the Mark V lineup, it is an enhanced revision of the DS200LDCCH1 base model, featuring three functional updates that improve reliability and performance.

Key Functions:

• Provides control over motor operations, device I/O, and communication interfaces

• Facilitates signal processing and coordination between the turbine drive and external systems

• Designed for gas, steam, and wind turbine applications

Hardware Features:

The DS200LDCCH1AMA includes several specialized components to support high-speed, fault-tolerant operations:

Microprocessor Architecture:

• DCP (Drive Control Processor):
  Manages analog/digital I/O signals entering the board

• LCP (LAN Control Processor):
  Filters and processes LAN communication signals

• MCP (Motor Control Processor):
  Handles primary digital motor control functions

• CMP (Co-Motor Processor):
  Assists MCP with additional processing when needed

Additional Hardware Elements:

• Attachable alphanumeric keypad for diagnostics and configuration

• Manually-operated RESET button for hardware-level resets

• Programmable soft reset option (requires software or specialized key)

• Automatic hardware watchdog for fault detection and emergency system trips

• Flash PROMs – Field-upgradable via PC

• Manual jumpers (Berg-type) – Used to configure hardware settings

Installation & Usage Notes:

• Designed to replace several earlier models (including DS200SDCC and DS200SLCC)

• Compatible with various GE turbine control systems and drive platforms

• Ensure jumper settings and PROM configurations match your system requirements

• For full diagnostic functions and installation guidance, refer to GE manual GEI-100216

Conclusion:

The GE DS200LDCCH1AMA board is a critical component in Mark V legacy systems, offering integrated control, high-speed LAN communication, and diagnostics in a single unit. With four onboard processors, configurable flash memory, and reset capabilities, it ensures reliable operation in demanding industrial environments.
