Product Introduction

The DS200SDCIG2A is an enhanced dual-channel servo interface and signal conditioning board for GE’s Mark V DS200 series, used in Speedtronic turbine control systems. It provides two independent servo interface channels with improved filtering, removable screw terminals, and better ESD protection.

The “A” revision of the SDCIG2 upgrades the base board with removable terminal blocks (original had fixed terminals), enhanced common-mode filtering on 4–20 mA inputs (60 dB vs 40 dB), improved ESD protection (±15 kV contact), and extended temperature range (−40°C to +70°C). Electrically identical to the base SDCIG2, but significantly easier to install and maintain.

Key Technical Specifications

Key Selling Points & Differentiators (A Revision Specific)

• Removable terminal blocks on all field connections – Original SDCIG2 had fixed terminals. Replace a damaged block without unwiring the entire board.
• Enhanced common-mode filtering (60 dB) – Original had 40 dB. Critical for long feedback cable runs (>500 ft) or near VFDs.
• Improved ESD protection (±15 kV contact) – Meets IEC 61000-4-2 Level 4. Field technicians without wrist straps will not damage the board.
• Extended temperature range (−40°C to +70°C) – Operates in unheated enclosures and cold climates.
• Switchable filtering per channel – Independent configuration per output and per feedback input.
• Torque card included – Laminated card with torque settings.
• QC includes dual-channel simultaneous test with enhanced filtering verification – Both channels tested concurrently.
• 2-year warranty

Frequently Asked Questions (FAQ)

Q: What is the difference between SDCIG2 (base) and SDCIG2A (A revision)?

Q: Can I replace a base SDCIG2 with an SDCIG2A without changing my wiring?
A: Yes—electrically identical. Transfer field wires from old fixed terminals to new removable blocks (remove block, land wires, plug into new board). Allow 2–3 hours for both channels.

Q: How do I configure the filters per channel?
A: Each output has a jumper for 1 kHz filter (ON = enabled). Each feedback pair has a jumper for 100 Hz or 1 kHz filter (3-position jumper). Jumpers accessible with board installed. Default: all filters ON.

Q: What is the output drive capability?
A: 20 mA per channel (same as base SDCIG2). For higher current (100 mA), use SDCIG1AEB.

Q: Does the SDCIG2A have LVDT excitation?
A: No. Pass-through only. Use external LVDT conditioner or SDCCG1AGD for direct LVDT input.

Q: What QC tests are specific to the SDCIG2A?
A: Standard tests per channel plus: removable terminal block torque verification (0.55 Nm), common-mode rejection (60 dB at 60 Hz), ESD test (±15 kV contact), low temperature operation (−40°C), dual-channel simultaneous step test, cross-channel interference (<5 mV), burn-in (72 hours at +65°C).

Q: What shipping protection?
A: Anti-static bag, ESD foam cradle, double-wall box. Each board ships individually. Spare terminal blocks in separate bag. Torque card included. Configuration jumper guide included.
