Product Introduction

The DS200SDCIG1ADA is a high-speed servo interface and signal conditioning board for GE’s Mark V DS200 series, used in Speedtronic turbine control systems. It provides ultra-low signal delay (<10 µs on outputs, <5 µs on feedback) by eliminating or bypassing all filtering stages.

The “ADA” suffix indicates a high-speed (low-latency) variant. Standard SDCIG1 boards have 1 kHz output filtering (160 µs delay) and 100 Hz feedback filtering (1.6 ms delay). The ADA revision removes these filters entirely or provides bypass jumpers. It is designed for high-speed servo applications where filtering delay is unacceptable: fast-acting fuel valves on aeroderivative turbines, high-speed direct-drive valves (bandwidth >200 Hz), and active vibration control systems.

Key Technical Specifications

Key Selling Points & Differntiators

• <10 µs output delay – Standard SDCIG1 has 160 µs (1 kHz filter). ADA is 16x faster. Essential for high-speed valve control.
• <5 µs feedback delay – Standard has 1.6 ms (100 Hz filter). ADA is 320x faster.
• No filtering stages – Filtering capacitors removed or bypassed. No phase lag at high frequencies.
• Full bandwidth (>50 kHz) – Passes high-frequency control signals without attenuation.
• Same protection as standard – Surge protection (TVS diodes) retained. Isolation (1500 VAC) retained.
• Plug-compatible replacement – Same pinout as SDCIG1A. Drops into existing systems.
• QC includes delay measurement – Output and feedback delays verified with oscilloscope.
• 2-year warranty

Frequently Asked Questions (FAQ)

Q: What is the difference between SDCIG1A (standard) and SDCIG1ADA (high speed)?

Q: What is the trade-off for high speed?
A: Noise rejection. The ADA board has no filtering, so high-frequency noise (VFDs, switching power supplies, radio interference) passes through to the servo controller. For high-speed applications, the valve bandwidth is also high (200 Hz+), so noise may be amplified. Ensure clean installation: shielded cables, proper grounding, ferrite beads. We include noise mitigation guide.

Q: Can I switch between filtered and unfiltered modes?
A: Yes. The ADA board has jumper positions for each output and each feedback pair. Default: bypass (unfiltered). Install jumper to enable standard 1 kHz output filter or 100 Hz feedback filter. The board becomes functionally identical to SDCIG1A with filters enabled.

Q: What valves require <10 µs delay?
A: Very few. Most electro-hydraulic servo valves have mechanical response >5 ms. <10 µs delay is irrelevant. Applications requiring ADA:

• Direct-drive valves (Moog DDV, bandwidth 300 Hz)
• Piezoelectric actuators (bandwidth 1 kHz)
• Active magnetic bearings (vibration control at high frequencies)
• Aeroderivative fuel valves (LM2500, LM6000)

Q: What QC tests are specific to the ADA revision?
A: Standard tests plus: output delay measurement (<10 µs with oscilloscope), feedback delay measurement (<5 µs), bandwidth verification (>50 kHz), filter bypass jumper test, noise susceptibility (inject 10 kHz, 1 V p-p, verify no oscillation).

Q: What shipping protection?
A: Anti-static bag, ESD foam cradle, double-wall box. Each board ships individually. High-speed configuration guide included.
