Description
Product Overview
The GE DS2020CMB1206CGDDD8E is a specialized control module assembly designed for GE LS2100 Innovation Series static starter equipment and related turbine starting systems. This module is part of the DS2020 family used in load commutated inverter (LCI) applications, where controlled power conversion is required to accelerate large synchronous motors or gas turbine generator shafts during startup sequences. The GE DS2020CMB1206CGDDD8E functions as a hardware assembly within the LCI control architecture, providing electrical interfaces and circuit support for system operation.
The GE DS2020CMB1206CGDDD8E belongs to the GE Mark V / DS200 control hardware ecosystem and is associated with static starter assemblies used in demanding industrial power applications. The module incorporates multiple circuit elements including connector interfaces, resistor network arrays, jumper selections, and capacitor components. These elements support signal routing, configuration functions, and electrical coordination within the larger LCI system.
Installed in turbine starting systems, the GE DS2020CMB1206CGDDD8E works as part of a larger converter arrangement rather than as a standalone PLC-style controller. Its role depends on the complete static starter design, including associated power modules, control cards, firing circuits, and protection hardware. To be completely transparent, replacement selection should include verification of the complete part number, revision level, cabinet location, and installed LCI configuration before commissioning.
For maintenance teams supporting GE turbine assets, this module is typically considered during static starter repair, lifecycle maintenance, and legacy equipment restoration. A correct replacement can help maintain the original control architecture without requiring extensive panel modifications. Before installation, engineers should inspect connectors, mounting hardware, cable assemblies, and surrounding converter components because failures in LCI systems are often related to multiple interacting power and control elements.
The practical value of the GE DS2020CMB1206CGDDD8E comes from supporting continued operation of existing GE starting systems where hardware compatibility is critical. Careful functional testing after installation remains necessary before returning the turbine starting package to normal service.

Frequently Asked Questions (FAQ)
1. What is the GE used for?
The is a control module assembly used in GE Innovation Series static starter systems. It supports the electrical interface and control functions required inside load commutated inverter equipment used for turbine starting applications.
2. Can I hot-swap the GE ?
No. This module belongs to a static starter power conversion system and should be replaced only after proper shutdown and isolation.
Recommended replacement procedure:
- Disconnect and verify system power isolation.
- Record module location and wiring arrangement.
- Remove the existing assembly.
- Install the replacement module.
- Perform startup diagnostics and functional checks.
3. Does the GE support firmware v3.1?
The is a hardware assembly, not a programmable controller CPU. Firmware compatibility is generally not the primary consideration.
Engineers should verify:
- Board revision
- Cabinet configuration
- Associated control boards
- LCI software package compatibility
4. Will replacing the GE erase my turbine control logic?
No. The module does not normally store the primary turbine application logic.
After replacement, technicians should verify:
- LCI communication status
- Control signal paths
- Protection circuits
- Startup sequence operation
5. How can I verify a New Surplus GE ?
Recommended inspection steps:
- Confirm GE part number marking.
- Verify complete ordering code.
- Inspect connectors and PCB condition.
- Check storage environment.
- Compare hardware revision with the installed unit.
6. What failures are commonly associated with DS2020 modules?
Typical issues may include:
- Aging capacitors
- Connector degradation
- Electrical stress from converter faults
- Heat-related component aging
- Damage caused by upstream power section failures
A replacement module should be installed only after identifying the original failure cause.
7. Is the GE suitable for turbine upgrade projects?
The module is primarily intended for maintaining existing GE and related legacy static starter systems. For modernization projects, engineers should evaluate the complete starter architecture, control interface requirements, and available replacement strategy before selecting hardware.
