Product Introduction
GE DS200LDCCH1AKA is a Drive Control / LAN Communication (LDC) board for the GE Speedtronic Mark V control system family. It is used in Mark V turbine and drive control applications where multiple processing functions and LAN communication must be integrated on a single board.
The LDC board contains multiple microprocessors, each assigned to a dedicated function. One microprocessor handles drive control processing, another handles motor control processing, and another provides LAN network control. This architecture allows the board to manage drive-related operations and communicate with other systems over the Mark V LAN.
If the board malfunctions or does not deliver expected performance, a soft reset may be performed by pressing the reset button while the board remains powered. A hard reset (power cycle) should be avoided unless a trip condition or drive fault requires it. Only qualified personnel should perform resets, as live voltage may be present inside the board cabinet.
The DS200LDCCH1AKA belongs to the LDCCH1 family. Related variants such as DS200LDCCH1ALA and DS200LDCCH1ANA are documented within the Mark V ecosystem, but public sources do not fully confirm the exact I/O count, connector pinout, microprocessor type, or LAN protocol for the AKA suffix. The specific configuration should be verified from the physical board label and GE Mark V system documentation before installation.

Note: Public documentation confirms the LDC function, multi-microprocessor architecture, drive/motor/LAN control roles, and reset behavior for the DS200LDCCH1 family. The exact I/O count, connector layout, LAN protocol, and microprocessor type for the AKA suffix should be confirmed from the physical board label and GE Mark V manuals.
Quality Control Process (DYNAMIC GENERATION)
- Visual and label inspection. We check the part number, revision suffix, PCB surface, connectors, LEDs, reset button, and mounting hardware for damage or corrosion.
- Connector and continuity check. All board connectors are verified for correct pin continuity and no short circuits.
- Reset button verification. The reset button is inspected for proper presence and mechanical condition.
- Configuration verification. Any jumpers, markings, or board-specific settings are recorded and compared against the original board or system documentation.
- Final packaging. After passing inspection, the board is anti-static bagged and foam-packed for shipment.
Replacement Pitfall Guide (DYNAMIC GENERATION)
❗ Verify the exact suffix. DS200LDCCH1AKA belongs to the LDCCH1 family; related variants such as DS200LDCCH1ALA and DS200LDCCH1ANA may differ in configuration.
❗ Record LAN and drive settings before removal. Document any LAN address, drive parameters, and connector positions for the replacement board.
❗ Use soft reset when possible. Press the reset button while power is applied rather than performing a hard power cycle, unless a trip condition requires it.
❗ Label all connectors. The LDC board may carry drive control, motor control, and LAN signals; incorrect reconnection can cause drive faults.
❗ Confirm system assignment. Verify that the target Mark V chassis and backplane support this LDC variant before installation.
❗ Observe live-voltage safety. The reset button may require access inside a powered cabinet; only qualified personnel should perform this operation.
❗ Handle as ESD-sensitive equipment. Always use anti-static wrist straps and handling procedures during removal, installation, and storage.
Keep these in mind and you’ll cut 90% of rework time.
