Functional Overview (Datasheet)
The DS200LDCCH1ALA functions as the “brain” of the drive assembly, coordinating between field inputs and control logic.
- Process Coordination: The four onboard microprocessors divide tasks to prevent latency. While the MCP handles the standard motor control algorithms, the CMP provides extra “headroom” for complex mathematical calculations without interrupting the core control loop.
- Networking and I/O: The board achieves connectivity through various bus systems. If utilizing Genius, CPL, or C-Bus systems, the board typically requires an additional terminal board interface (such as the DS200ADCI).
- System Protection: Integrated software and hardware watchdogs monitor the board’s health. The onboard diagnostic LEDs allow technicians to quickly identify faults in the LAN or drive control logic.
- Drive Integration: It is designed for seamless integration with EX2000 series exciters and DC2000 drive controllers, facilitating precise speed and torque regulation for industrial turbine applications.

Technical Description
The “ALA” suffix in the part number denotes specific hardware and software revisions:
- A: Parent board revision.
- L: Software/Firmware configuration.
- A: Subsequent hardware minor revision.
The board features several physical components critical for installation:
- I/O Connectors: Multiple pin headers for connecting to the backplane and peripheral interface boards.
- Configuration Jumpers: Used to set hardware-specific parameters such as clock speeds, bus addresses, and signal levels.
- Test Points: Gold-plated test points are available for oscilloscope or multimeter probing during commissioning.
Country of Origin
- Manufacturing Location: United States (USA).
Installation Guidelines
- Static Safety: The board contains sensitive CMOS components. It must be handled in an ESD-safe environment using a grounded wrist strap.
- Software Compatibility: Before replacing an existing board, ensure that the firmware revision (EPROM chips) matches the configuration of the turbine or drive system to avoid “Configuration Mismatch” errors.
- Mounting: The board should be securely slotted into the chassis with all screws tightened to ensure proper grounding through the standoffs.
