Product Introduction

The DS200SDCCG5A is a deca-channel servo drive controller for GE’s Mark V DS200 series, used in Speedtronic turbine control systems. It provides ten independent servo control loops on a single board—the absolute highest channel count servo controller ever produced for Mark V.

The SDCCG5A is essentially ten SDCCG1 controllers on one PCB. It is designed for the most extreme turbine control systems requiring coordination of up to ten valves or actuators: advanced gas turbines with 10 fuel stages, large steam turbines with 10 admission/extraction/bypass/dump valves, or large compressor stations with 10 anti-surge recycle valves. Maximum channel density.

Deca-Channel Features (SDCCG5A)

Key Selling Points & Differentiators

• Ten servo controllers in one slot – Maximum channel density. Saves nine rack slots versus SDCCF1 boards.
• Independent PID per channel – Tune each of the ten 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 ten channels simultaneously – All loops update concurrently at 1 kHz.
• Synchronized output capability – Coordinate multiple valves. Jitter <5 µs.
• QC includes ten-channel simultaneous closed-loop test – All channels tested concurrently.
• 2-year warranty – Covers all ten channels.

Frequently Asked Questions (FAQ)

Q: What is the total backplane current draw?
A: 6.5 A maximum at 5 VDC. This exceeds standard Mark V power supplies. You MUST use an external 5 V supply (15 A minimum). The board will not function in a standard Mark V rack without external power.

Q: What is the total power dissipation?
A: Logic: 5 V x 6.5 A = 32.5 W. Requires forced air cooling (400 LFM minimum). Heatsink included but not sufficient alone.

Q: Can the SDCCG5A fit in a standard Mark V rack?
A: Yes—physically 6U x 8HP. But power and cooling requirements exceed standard rack capabilities. Requires external power supply and forced air cooling kit.

Q: What applications need ten servo channels?
A: Extremely rare. Advanced gas turbines with 10 fuel stages (some aeroderivative installations), large steam turbines with HP, IP, LP, 2 extraction, 2 bypass, 2 dump, 1 admission valves. Consult GE turbine specifications.

Q: What QC tests are specific to the SDCCG5A?
A: Standard tests per channel plus:

• Ten-channel simultaneous step test
• Cross-channel interference (all 45 channel pairs)
• Synchronization test (all ten outputs)
• Thermal imaging at full load with cooling
• Total backplane current (6.5 A max)
• Burn-in: 72 hours at +50°C with forced air cooling

Q: What shipping protection?
A: Anti-static bag, ESD foam cradle, double-wall box with “HEAVY,” “HIGH CURRENT,” “FRAGILE” labels. Each board ships individually. Pallet required. External power supply and cooling kit ship separately. Site visit strongly recommended.
