About the DS200LDCCH1ALA

The DS200LDCCH1ALA is a drive control and local area network (LAN) communications card manufactured by General Electric. It is part of the Mark V Turbine Control System series, designed specifically for use in wind, gas, and steam turbine automated drive assemblies.

While the Mark V Series is now obsolete and discontinued due to functional obsolescence identified by the manufacturer, it remains highly sought after as one of the final GE product series to incorporate the patented Speedtronic control system technology—originally introduced with the Mark I Series in the late 1960s.

The DS200LDCCH1ALA is an updated revision of the original DS200LDCCH1 parent board, featuring three significant product revisions that improve its functionality.

Hardware Features and Specifications

This board is designed for installation in GE's DIRECTO-MATIC 2000 series drives and exciters, providing a range of device, motor, and I/O control functions.

It includes four onboard microprocessors:

• Drive Control Processor (DCP): Handles filtering of digital and analog I/O signals.

• LAN Control Processor (LCP): Manages LAN communication systems connected to the drive.

• Motor Control Processor (MCP): Performs initial processing of digital I/O communications.

• Co-Motor Processor (CMP): Provides additional processing power when MCP capacity is exceeded.

An attachable alphanumeric keypad is included to facilitate system diagnostics and configuration.

Bus System Compatibility

The DS200LDCCH1ALA supports I/O processing through the following bus systems:

• DLAN+ LAN Protocol Bus System

• DLAN (Smaller and Early Larger Drives) LAN Protocol

• Genius Interface Board Bus System

• CPL Interface Board Serial Link Bus System

• C-Bus Interface Board Differential Bus System

Note: For Genius, CPL, and C-Bus systems, an additional optional terminal board (DS200ADCI Board) is required.

Additional Features

• A RESET button is provided to clear functional faults and support diagnostics.

• The PCB is protected with a conformal coating for enhanced durability.

Shipping and Support

• Products purchased from AX Control are shipped in a protective static-resistant plastic bag.

• Customers are advised to review the manufacturer’s installation parameters carefully before removing the board.

• A comprehensive wiring and installation guide is included in the series manual and datasheet.

• Original technical support for the Mark V series was provided by General Electric.
