DS200LDCCH1ARA

About the DS200LDCCH1ARA

• The DS200LDCCH1ARA is a Drive Control/LAN Communications Board by General Electric.
• It's for the Mark V Turbine Control System Series, used in gas, steam, and wind turbine automated drive assemblies.
• Though a legacy series, 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

• 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.
• Includes programmable memory with factory configurations that can be edited via a laptop and serial cable (6 ft or less).
• Has 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.
