Product Introduction

The DS200SDCCG3A is a hexa-channel servo drive controller for GE’s Mark V DS200 series, used in Speedtronic turbine control systems. It provides six independent servo control loops on a single board—for the largest turbine control applications requiring coordination of up to six valves or actuators.

The SDCCG3A is essentially six SDCCG1 controllers on one PCB. It is designed for the most complex turbine systems: heavy-duty gas turbines with multiple fuel stages (pilot, primary, secondary, tertiary), steam turbines with multi-valve admission (HP, IP, LP, extraction, bypass, dump), and large compressor stations with multiple anti-surge recycle valves.

Key Selling Points & Differentiators

• Six servo controllers in one slot – Controls up to six independent valves. Saves five rack slots versus SDCCF1 boards.
• Independent PID per channel – Tune each of the six channels independently.
• Redundant feedback per channel (2 x 4–20 mA) – Each channel accepts two position feedback signals.
• Fast 1 ms update rate on all six channels simultaneously – All loops update concurrently at 1 kHz.
• Synchronized output capability – Coordinate multiple valves (e.g., fuel staging) to move simultaneously. Jitter <5 µs.
• QC includes six-channel simultaneous closed-loop test – All channels tested concurrently.
• Configuration backup available – Extract configuration from your old board(s) into replacement.
• 2-year warranty – Covers all six channels.

Frequently Asked Questions (FAQ)

Q: What is the total backplane current draw?
A: 3.8 A maximum at 5 VDC. Most Mark V power supplies are rated 5–10 A at 5 V. Verify your system has sufficient capacity. We recommend a dedicated power supply for the SDCCG3A in heavily loaded racks.

Q: What are the cabinet requirements?
A: 6U x 8HP (double-width, approx 330 mm deep with cables). Standard Mark V rack fits.

Q: Can I replace six SDCCF1 boards with one SDCCG3A?
A: Yes, but requires significant reconfiguration (20–30 hours). We strongly recommend a factory site visit.

Q: What QC tests are specific to the SDCCG3A?
A: Standard tests per channel plus:

• Six-channel simultaneous step test
• Cross-channel interference (all channel pairs)
• Synchronization test (all six outputs)
• Thermal imaging (all six channels at full load)
• Burn-in: 72 hours at +65°C, all channels running

Q: What shipping protection?
A: Anti-static bag, ESD foam cradle, double-wall box with “HEAVY,” “FRAGILE” labels. Each board ships individually. Configuration extraction service available.
