DS200LDCCH1ARA

About the DS200LDCCH1ARA

The DS200LDCCH1ARA is a Drive Control/LAN Communications Board by General Electric. This board was designed for the Mark V Turbine Control System Series, used in gas, steam, and wind turbine automated drive assemblies.

The Mark V is notable as one of the final GE series to use Speedtronic technology.

This board isn't the original; the DS200LDCCH1 parent board lacks its three significant revisions.

Hardware & Diagnostics

This board features multiple microprocessors for drive, motor, I/O, and LAN control.

Voltage is managed by standard Mark V Series components like transistors, resistors, capacitors, and diodes.

The DS200LDCCH1ARA also includes programmable memory with factory configurations that can be edited via a laptop and serial cable (6 ft or less).

There is a display screen for an optional handheld keypad, allowing minor adjustments and diagnostics.

Eight testpoints are included for diagnostics, such as:

• TP8 Drive Type-Specific Motor Current
• TP25 Positive Power Supply
• TP26 Negative Power Supply
• TP27 & TP31 Common Reference Signal
• TP29 Input Line Frequency
• TP30 Regulated Positive Volt Power Supply
• TP37 Drive Type-Specific Voltage

Its performance and dimensions are altered by two functional (A, R grades) and one artwork (A grade) revision.

A connector for a keypad (with buttons and a two-line display) allows minor configuration changes.

Configuration & Installation

For major configuration changes, use a laptop with editing software.

Before connecting: Remove and verify power to the drive.

Ensure the laptop's serial port is properly configured.
