Product Overview

The DS200LDCCH1ANA is a Drive Control and LAN Communications Board developed by General Electric for use in the Mark V Turbine Control System Series. This legacy board supports critical drive, motor, and communication functions in gas, steam, and wind turbine automation systems.

Though the DS200LDCCH1ANA builds upon the original DS200LDCCH1 base board, it features three key revisions that enhance performance and functionality. These revisions impact physical dimensions and electrical specifications.

The Mark V is one of the last GE Speedtronic control systems to incorporate the company’s patented turbine automation technology, which dates back to the Mark I platform in the late 1960s.

Key Features & Functional Capabilities

• Supports drive control, motor processing, LAN signal management, and I/O coordination

• Designed for integration within GE’s DIRECTO-MATIC 2000 drives and Mark V systems

• Backwards-compatible with earlier revisions (excluding latest updates)

Microprocessor Configuration

The board includes four dedicated microprocessors, each with a specific role:

• Drive Control Processor (DCP) – Handles drive signal logic

• Motor Control Processor (MCP) – Manages motor operation signals

• Co-Motor Processor (CMP) – Assists MCP with additional processing when required

• LAN Control Processor (LCP) – Filters and processes LAN communications

Hardware Details

• Protective conformal coating on PCB for environmental resistance

• Integrated diodes, resistors, and capacitors for voltage regulation

• Six flash PROMs (U7–U21) store configuration data (field-reprogrammable)

• Includes a stab connector for high-noise applications

• Voltage insulation components enhance system protection

Reset & Diagnostics Procedures

Soft Reset (Recommended):

• Press and hold the Reset button on the board for approximately 5 seconds

• Safely clears faults while maintaining power

• Should only be performed by qualified personnel due to electrical hazard risk

Hard Reset (Not Recommended Unless Necessary):

• Triggered via full power interruption

• Used only during drive malfunction or trip condition

⚠️ Important:
The DS200LDCCH1ANA’s three product revisions may impact system compatibility and installation fit. Always confirm your system's firmware and hardware requirements prior to replacement.

Conclusion

The GE DS200LDCCH1ANA offers enhanced drive and LAN communication capabilities for legacy Mark V systems. Its robust hardware, configurable memory, and layered processing architecture make it a reliable solution for demanding turbine control applications.
