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 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.
