DS200LDCCH1AKA

About the DS200LDCCH1AKA

• The DS200LDCCH1AKA is a drive control and local area network (LAN) communications board developed by General Electric.
• It was designed for GE's Mark V Turbine Control System series of drive boards.
• This card is compatible with GE DIRECTO-MATIC 2000 exciters and drives.
• Onboard microprocessors provide various interfacing capabilities, including LAN communications, drive resets, motor and drive processing, and operator interface.
• The Mark V Series, despite its applications in steam, wind, and gas turbine automated drive assemblies, is considered an obsolete legacy product series due to manufacturing discontinuation.
• However, the Mark V Series is also one of the final General Electric Mark product series to incorporate their patented Speedtronic control system technology.
• The DS200LDCCH1AKA is not the original product for its specific functionality within the Mark V Series; the DS200LDCCH1 parent board lacks its three significant product revisions.

Hardware Tips and Specifications

• Four microprocessors are integrated onto the board to cover I/O and drive control settings:
  • LAN Control Processor (LCP): Accepts and converts five different bus systems.
  • Drive Control Processor (DCP): Controls peripheral I/O devices (e.g., timers, encoders) and converts analog/digital I/O.
  • Motor Control Processor (MCP): Processes I/O communications and motor control circuits.
  • Co-Motor Processor (CMP): Provides additional processing power if the MCP's power is insufficient.
• An alphanumeric keypad is attached for easy access to onboard system diagnostics and settings.
• The board includes numerous voltage limitation components (capacitors, resistors, integrated circuits), each with a factory-printed nomenclature label.
• The base circuit board is protected by a special conformal style of PCB surface coating.
• For diagnostics, the board features several diagnostic testpoints and a singular RESET button.
• It has a less-common communicative LED keypad display and several DN1 bar graph LEDs.
• PROMs (Programmable Read-Only Memory) store onboard software:
  • Six flash PROM components store configuration data.
  • The EEPROM contains field-adjustable parameters.
• Reset options include:
  • A pushable RESET pushbutton for fatal functional faults.
  • Soft resets achievable through programming alteration or a Mark V Series Programmer Module's reset key.
• A stab connection is available for LAN interface board stiffening in high-noise environments.
