Product Introduction

The DS200SDCCG4A is an octo-channel servo drive controller for GE’s Mark V DS200 series, used in Speedtronic turbine control systems. It provides eight independent servo control loops on a single board—the highest channel count servo controller in the entire Mark V product family.

The SDCCG4A is essentially eight SDCCG1 controllers on one PCB. It is designed for the most complex and large-scale turbine control systems requiring coordination of up to eight valves or actuators: advanced gas turbines with 8 fuel stages, steam turbines with 8 admission/extraction valves, or large compressor stations with 8 anti-surge recycle valves.

Octo-Channel Features (SDCCG4A)

Key Selling Points & Differentiators

• Eight servo controllers in one slot – Controls up to eight independent valves. Saves seven rack slots versus SDCCF1 boards. Maximum channel density.
• Independent PID per channel – Tune each of the eight 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 eight channels simultaneously – All loops update concurrently at 1 kHz.
• Synchronized output capability – Coordinate multiple valves to move simultaneously. Jitter <5 µs.
• QC includes eight-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 eight channels.

Frequently Asked Questions (FAQ)

Q: What is the total backplane current draw?
A: 5.0 A maximum at 5 VDC. This exceeds the capacity of many Mark V power supplies (typical 5–10 A). The SDCCG4A alone draws 5 A. You must use a high-capacity power supply (DS200PCCAG5A or equivalent) and minimize other modules. For most systems, you will need an external 5 V supply (special order). We provide load calculation worksheet.

Q: What are the cabinet requirements?
A: 6U x 8HP (double-width, approx 330 mm deep with cables). The board generates significant heat (25 W dissipation). Ensure forced air cooling (200 LFM minimum) across the board.

Q: Can I replace eight SDCCF1 boards with one SDCCG4A?
A: Yes, but requires extensive reconfiguration (30–40 hours). We strongly recommend a factory site visit for first-time installations. We provide conversion worksheet.

Q: What is the maximum cable length?
A: 1000 ft (300 m) for outputs (10 mA at 10 V, voltage drop becomes significant beyond 1000 ft). 500 ft (150 m) for 4–20 mA feedback due to cable capacitance.

Q: What QC tests are specific to the SDCCG4A?
A: Standard tests per channel plus:

• Eight-channel simultaneous step test
• Cross-channel interference (all channel pairs)
• Synchronization test (all eight outputs)
• Thermal imaging (all eight channels at full load)
• Total backplane current measurement (5.0 A max)
• 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,” “HIGH CURRENT,” “FRAGILE” labels. Each board ships individually. Configuration extraction service available. Pallet recommended for shipment.
