Meta Description
Get professional technical specs, lead times, and on-site stocking advice for the GE DS200SDCCG1A Mark V Drive Control Card. Keep your turbine controls running.
Main Body
The GE DS200SDCCG1A is the primary Drive Control Card (SDCC) for EX2000 excitation systems and Mark V turbine control drives. This central processing board executes critical control algorithms, processes system feedback, and governs customer I/O via three onboard 16-bit microprocessors.
In my field deployments of Speedtronic Mark V control frameworks, the most common commissioning oversight is failing to hand-transfer the software configuration parameters from the old card’s EEPROM before physically swapping the hardware. The DS200SDCCG1A operates with three dual-ported RAM-connected microprocessors that divide task loads—specifically motor control, drive control, and co-motor processing—to eliminate processing bottlenecks during complex turbine operations. Auxiliary boards mount directly on top of this host card via integrated pin connectors.
Parameter: Value
Part Number: DS200SDCCG1A
Series: Mark V / EX2000 Speedtronic
Processor Architecture: Three 16-bit microprocessors
RAM Type: Dual-ported shared memory
Onboard Indicators: 10 Diagnostic LED array
Operating Temperature: -30 to 65 °C
Board Dimensions: 6.25 in x 4.25 in
OEM Manual: GEI-100029
Product Condition: New Surplus or Tested Refurbished
Warranty: 12 months Classified as a critical Class A item in ABC analysis, a failure of this primary processor card results in immediate shutdown of the gas or steam turbine. Because standard vendor lead times for a factory-sealed or fully tested surplus unit typically run 4 to 6 weeks, relying on external spot markets during an emergency risks massive financial loss. Plants running critical turbine drives should maintain a buffer stock of 1 unit on-site as an insurance policy.
We can optimize our overall carrying cost by managing these through regional frame agreements with preferred suppliers, avoiding high holding costs while ensuring immediate next-day delivery when a card goes dark.
This legacy card is not recommended for new greenfield control networks, where newer digital controls are standard, but remains essential for active systems requiring strategic hoarding before the secondary market supply dries up completely.
Quick Conclusions
- Keeping 1 on-site spare reduces catastrophic turbine downtime from weeks to a few hours.
- Auxiliary expansion cards must be unmounted from the failed board and reinstalled on the replacement.
- All cable routing must avoid contact with adjacent high-voltage components in the drive cabinet.
- Always confirm the jumper settings on the new board match your old card configuration prior to powering up.
FAQ
- What is the primary function of the 10 diagnostic LEDs?The LEDs display internal fault codes, allowing maintenance teams to diagnose processor or communication failures directly.
- Can I swap the DS200SDCCG1A while the turbine cabinet is powered?No. This board handles sensitive static-prone signals and high-density logic; power must be completely locked out before replacement.
- Does this control card come pre-loaded with drive firmware?No. Configuration parameters and system-specific parameters must be downloaded from a local workstation during commissioning.
